December 16, 2024Aluminum is one of the most commonly used materials for machining today. In fact, the CNC machining process for aluminum is second only to steel in terms of frequency of use.
In its high-purity form, the chemical element aluminum is soft, ductile, non-magnetic, and has a silvery-white appearance. However, this element is not used only in its pure form. Aluminum is often alloyed with various elements, such as manganese, copper, and magnesium, to form a variety of aluminum alloys with significantly improved properties. The most common machined aluminum alloys and their grades in different standards can be found here.
Advantages of using aluminum for CNC machined parts
While there are countless aluminum alloys with varying degrees of characteristics, there are some basic characteristics that apply to basically all aluminum alloys.
Workability
Aluminum can be quickly shaped, fabricated, and machined by a variety of different processes. Aluminum can be cut quickly and easily by machine tools because it is soft, easy to cut, inexpensive, and requires less effort than steel. These characteristics are great advantages for both machinists and customers ordering parts. Furthermore, aluminum’s superior machinability means that it is less likely to deform during machining. Given that it allows CNC machines to achieve a higher degree of resistance, their accuracy will be higher.
Strength of Aluminum
Aluminum is about one-third the density of steel, making it relatively lighter in mass. Despite its light weight, aluminum is very strong. This combination of strength and weight is called the specific strength of the material. Aluminum’s high specific strength makes it suitable for parts needed in many industries, such as the automotive and aerospace industries.
Corrosion resistant
Aluminum resists scratching and corrosion in conventional marine and atmospheric environments. This property can also be enhanced by anodizing. It is important to note that the corrosion resistance of different grades of aluminum varies. The most regular and common CNC machined grades instead have the strongest resistance.
Low Temperature Performance
Most materials lose some of their quality properties below freezing. For example, carbon steel and rubber become brittle at low temperatures. Aluminum, on the contrary, retains its softness, ductility and strength at very low temperatures.
Conductivity
The electrical conductivity of pure aluminum is about 37.7 million Siemens/meter at room temperature . Although aluminum alloys are less conductive than pure aluminum, they are sufficient for applications in electronic components. On the other hand, if the desirable properties of a machined part are not electrical conductivity, aluminum would not be a suitable material for it.
Recyclability
Since the CNC machining process is a subtractive manufacturing process, it generates a large amount of chips, also known as scrap. Aluminum is highly recyclable and requires relatively little energy, effort and cost to recycle. This makes it a favorite among those who want to recoup expenses or reduce material waste. It also makes aluminum a more environmentally friendly material to process.
Anodizing possibilities
Anodizing, a surface machining process, improves the material’s resistance to wear and corrosion, which is extremely easy to achieve with aluminum. This process also makes it easier to color machined aluminum parts.
CNC machining process for aluminum
Aluminum is machined through some of the existing CNC machining processes. Some of these processes are listed below.
CNC Turning
In a CNC turning operation, the workpiece rotates while the single-point cutting tool remains stationary along the axis. Both the workpiece and the tool will rely on the machine tool to perform feed movements against each other to achieve material removal.
CNC Milling
CNC milling is the most common process used when machining aluminum parts. These processes involve the rotation of a multi-point cut along an axis, while the workpiece remains stationary along the axis. The cutting action and subsequent material removal is realized by a feed motion, either of the workpiece or of the cutting tool or a combination of both. This action can be carried out along multiple axes.
Notching
Recess machining, known as recess milling, is a form of CNC milling used to machine a hollow recess in a part.
End face machining
Face machining involves the use of face turning or face milling to create a flat cross-section on the surface of a workpiece.
CNC drilling
CNC drilling is the process of punching a hole in a workpiece. In this process, a multipoint rotary cutting tool of a specific size is perpendicular to the surface to be drilled and moves in a straight line to effectively punch the hole.
Tools for machining aluminum
In the choice of CNC machining tools for aluminum, there are so many influencing elements.
Tool Design
The different styles of a tool’s shape affect its efficiency in machining aluminum. One of them is the number of grooves in the tool. In order to avoid difficulties in discharging chips at high speeds, a cutting tool for CNC machining of aluminum should have 2-3 grooves. Too many notches means narrower chip discharge passages, which can lead to large chip jams from aluminum alloys. When cutting forces are low and chip removal is critical to the process, you should use a tool with 2 notches. If you want to achieve the perfect balance of chip removal and tool strength, you should use a 3-notch tool.
Helix angle
The helix angle is the angle formed between the center axis of the tool and the straight line cut along the cutting edge. It is an important feature of cutting tools. Although a larger helix angle clears part chips more quickly, it increases friction and heat during the cutting process. In high-speed CNC machining of aluminum, this can result in chips fusing to the surface of the tool. On the other hand, a smaller helix angle generates less heat and may not be as effective at removing chips. For machining aluminum, a 35- or 40-degree helix angle is suitable for roughing, while a 45-degree helix angle is best for finishing.
Clearance angle
The clearance angle is another important factor for a tool to function properly. Too much angle can cause the tool to drill into the workpiece and make a gurgling sound. On the other hand, too little of an angle can cause friction between the tool and the workpiece. The best clearance angle for CNC machining of aluminum is between 6 and 10 degrees.
Material of the tool
Tungsten carbide is the material of choice for use as a cutting tool for CNC machining of aluminum. Because aluminum is a soft cut, it is important that the tools used to cut aluminum are not hard, yet retain the ability to cut sharp edges. Carbide cutting tools have this ability, mainly by two points: alloy grain size and binder ratio. Although a larger grain size makes the material harder, a smaller grain size ensures that the material is more resilient and impact resistant, which are the properties we really need. Smaller grains allow cobalt to achieve a fine grain structure and material strength.
However, cobalt and aluminum react at high temperatures to form aluminum chip tumors on the tool surface. The key to minimizing this reaction is to use carbide tools with the right amount of cobalt (2 to 20%) while still maintaining the required strength. Carbide tools can usually withstand the high speeds of CNC machining of aluminum better than steel tools. In addition to the material of the tool, coatings are an important factor in cutting efficiency. Zirconium dinitride, titanium diboride and diamond-like coatings are all suitable tool coatings for CNC machining of aluminum.
Feed and speed
The cutting speed is the speed at which the cutting tool is rotating. Aluminum can withstand very high cutting speeds, so the cutting speed of aluminum alloys depends on the limits of the machine tool used. This speed should be as fast as the actual speed at which the aluminum is CNC machined, as this reduces the possibility of chip-rule formation, saves time, reduces part temperatures, improves chip breakage and improves finishing finishes. The exact speed used varies depending on the aluminum alloy and tool diameter.
The feed rate is the distance the workpiece or tool moves for each revolution of the tool. The choice of feed is dependent on the degree of finish, strength and stiffness of the workpiece desired. Rough cutting requires a feed rate of 0.15-2.03 mm/rev, while finish cutting requires a rate of 0.05-0.15 mm/rev.
Cutting fluid
Even if aluminum is a good machinable, never cut it in a dry state, as this will encourage the formation of chip tumors. Suitable cutting fluids for CNC machining of aluminum are oil-based emulsions and mineral oils. Avoid cutting fluids that contain chlorine or reactive sulfur, which can stain aluminum.
Post-Processing Flow
After finishing machining an aluminum part, there are specific processes you can perform to enhance its physical, mechanical, and aesthetic properties. The most widely used processes are listed below.
Pearlized and sandblasted finishes
Pearlizing is a finishing process with a decorative effect. The process consists of a high-pressure air gun spraying small glass beads onto the machined part, effectively cleaning the material and ensuring that the surface of the part is smooth and flat and that the aluminum can have a smooth or matte finish. The main operating parameters of the bead finishing process are the size of the glass beads and the amount of high or low air pressure used. This process is only suitable if the dimensional tolerances of the part are not critical. Other processes, including polishing and lacquering, are also available in addition to bead-blasting, i.e. cleaning the material with a high-pressure stream of sand.
Protective layer
This process covers the use of other materials such as zinc, nickel, and chrome plating to overcoat aluminum parts. This is done to perfect the machining of the part and may be possible through an electrochemical reaction process.
Anodic oxidation
Anodizing is an electrochemical process in which an aluminum part is immersed in a dilute sulfuric acid solution and a voltage is applied to both the positive and negative terminals. This process effectively transforms the exposed surface of the part into a hard, non-reactive aluminum oxide coating. Both the density and thickness of the resulting coating depend on the consistency of the solution, the length of the oxidation, and the current. You can also use anodizing to color parts.
Powder Coating
The powder coating process consists of coating the parts with colored polymer powder using an electrostatic spray gun. The parts are then stored at a temperature of 200 degrees Celsius. Powder coating improves strength and resistance to abrasion, corrosion and impact.
Hot treatment
Parts made of heat-treatable aluminum alloys receive heat treatment to improve their mechanical properties.
CNC Machining of Aluminum Parts in Industry
As mentioned above, aluminum alloys possess many desirable properties. Therefore, CNC machining of aluminum parts is indispensable in many industries, as follows:
Aerospace: Given the high specific strength of aluminum alloys, many aircraft components are made from machined aluminum.
Automotive: Similar to the aerospace industry, many components in the automotive industry, such as driveshafts and other components, are made of aluminum.
Electrical: CNC machined aluminum parts are often used as electronic components in household appliances due to their high electrical conductivity.
Food/Pharmaceuticals: Aluminum parts do not react with most organic substances, so they play an important role in the food and pharmaceutical industries.
Sports: Aluminum is often used to make sports equipment such as baseball bats and sports whistles.
Cryogenic: Aluminum retains its mechanical properties at temperatures below freezing, making it popular for low-temperature applications.

December 9, 2024Aluminum Processing Industry Overview
According to the different processing techniques, aluminum processing products can be divided into two major categories;
One is the use of fusion casting – extrusion process production of aluminum profiles:
Aluminum rods extruded into aluminum profiles using the hot extrusion process; hot extrusion is the earliest of several extrusion processes used in the extrusion molding technology, it is in the hot forging temperature with the help of the material plasticity good characteristics of the metal for a variety of extrusion molding. At present, hot extrusion is mainly used in the manufacture of ordinary cross-section of long parts, profiles, tubes, bars and various machine parts. Hot extrusion can not only form good plasticity, relatively low strength of non-ferrous metals and their alloys, low, medium carbon steel, etc., but also can be formed into high strength high carbon, high alloy steel, such as structural special, stainless steel, high-speed tool steel and heat-resistant steel, etc.. As the billet must be heated to hot forging temperature for extrusion, often accompanied by more serious oxidation and decarburization and other heating defects, affecting the dimensional accuracy and surface roughness of the extruded parts. In general, machine parts hot extrusion molding, and then use cutting and other machining to improve the dimensional accuracy and surface quality of the parts.
Melting process flow:
Furnace loading → melting → stirring complete melting → add scrap → melting → add scrap → complete melting → sprinkle covering agent and slagging agent → slagging → stirring → sampling, pre-furnace analysis → add Al-Si (Sl-Cu, Cr additives), Mg ingot → stirring → sampling, post-furnace analysis → composition adjustment → refining → slagging re-covering → resting
The other is aluminum sheet and strip and aluminum foil produced using the hot rolling – cold rolling process. Among them, aluminum profiles are mainly used in construction and industrial fields, while aluminum sheet and foil are mainly used in home appliances, food and beverage, and battery fields:
Continuous casting slab or initial rolling slab as raw material, heated by a step heating furnace, high-pressure water dephosphorization into the roughing mill, roughing material by cutting the head, tail, and then into the finishing mill, the implementation of computer-controlled rolling, final rolling that is, after laminar cooling (computer-controlled cooling rate) and coiling machine coiling, become straight hair rolls. The head and tail of the straight hair coil is often tongue and fishtail shape, thickness, width accuracy is poor, there are often wave-shaped edge, folded edge, tower and other defects. Its volume weight is heavy, the inner diameter of the steel coil is 760mm. (General pipe making industry like to use.) The straight hair coil by cutting head, tail, cutting edge and more than one straightening, leveling and other finishing line processing, and then cut plate or re-roll, that is to become: hot rolled aluminum plate, flat hot rolled aluminum coil, longitudinal cut strip and other products. If the hot rolled finishing coils are pickled to remove oxidized skin and coated with oil, they will become hot rolled pickled coils.
With hot rolled aluminum coil as raw material, after pickling to remove the oxide skin for cold rolling, the finished product is rolled hard coil, due to continuous cold deformation caused by cold hardening of rolled hard coil strength, hardness, toughness and plastic index decline, stamping performance deterioration, can only be used for simple deformation of the parts. Rolled hard coil can be used as raw materials for hot-dip galvanizing plant, because the hot-dip galvanizing unit are set with annealing line. Rolled hard coil weight is generally 6 ~ 13.5 tons, aluminum coil inner diameter of 610mm. general cold rolled plate, coil should be continuous annealing (CAPL unit) or hood furnace for de-annealing treatment to eliminate cold hardening and rolling stress, to achieve the mechanical properties specified in the standard index. Cold rolled aluminum plate surface quality, appearance, dimensional accuracy are better than hot rolled plate.

December 5, 2024Aluminum is a non-ferrous metal in the largest amount of use, the most widely used metal materials, and its scope of application is still expanding. The use of aluminum production of aluminum products is a wide variety, countless, according to statistics has more than 700,000 kinds, from the building decoration industry to the transportation industry and aerospace and other industries have different needs. Introduce the processing of aluminum products and how to avoid processing deformation.
The superiority and characteristics of aluminum are as follows:
1.Low density. The density of aluminum is about 2.7g/cm3. it is only 1/3 of the density of iron or copper.
2. High plasticity. Aluminum has good ductility and can be made into various supplies by extrusion, stretching and other pressure processing means.
3. Corrosion resistance. Aluminum is a highly negatively charged metal, in natural conditions or anodic oxidation of the surface will generate a protective oxide film, with much better corrosion resistance than steel.
4. Easy to strengthen. The strength of pure aluminum is not high, but its strength can be improved by anodic oxidation.
5. Easy surface treatment. Surface treatment can further improve or change the surface properties of aluminum. Aluminum anodic oxidation process is quite mature, stable operation, has been widely used in the processing of aluminum products.
6. Good conductivity, easy to recycle.
Stamping of aluminum products
1.Cold Punch
Material used: Aluminum pellets. Using an extruder table and die for one-time molding, it is suitable for column-shaped products or product shapes that are difficult to achieve with the stretching process, such as oval, square, and rectangular products.
The tonnage of the machine used is related to the cross-sectional area of the product, the gap between the upper die punch and the lower die tungsten steel is the wall thickness of the product, and the vertical gap between the upper die punch and the lower die tungsten steel to the lower dead center at the completion of the press fit is the top thickness of the product.
Advantages: shorter molding cycle, lower development cost compared to stretching molds.
Disadvantages: Longer production process, large fluctuation of product size during the process, high labor cost.
2.Stretching
Use material aluminum skin. Using continuous mold machine table and molds for multiple deformation to make it reach the demand of shape, suitable for non-cylindrical body (products with curved aluminum).
Advantages: more complex and multiple deformation products in the production process of dimensional control is stable, the product surface is more polished.
Disadvantages: high cost of molds, relatively long development cycle, high requirements for the selection and accuracy of the machine.
Surface treatment of aluminum products
1. Sandblasting (shot blasting)
The process of cleaning and roughening metal surfaces using the impact of a high-speed sand stream.
This method of surface treatment of aluminum parts enables the surface of the workpiece to obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece can be improved, therefore improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, prolonging the durability of the coating film, and also contributing to the leveling and decoration of the coating. This process we often see in Apple’s various products.
2.Polishing
The use of mechanical, chemical or electrochemical effects, so that the surface roughness of the workpiece to reduce, in order to obtain a bright, flat surface processing methods. Polishing process is mainly divided into: mechanical polishing, chemical polishing, electrolytic polishing. Aluminum parts using mechanical polishing + electrolytic polishing can be close to the stainless steel mirror effect, the process, giving people a high-grade simple, fashionable future feeling.
3.Drawing
Metal drawing is the manufacturing process of repeatedly scraping lines out of aluminum sheets with sandpaper. Wire drawing can be divided into straight wire drawing, messy wire drawing, spinning wire drawing, thread drawing. The brushed metal process can clearly show each and every fine silk trace, thus making the metal matte with a fine hairline luster, and the product is both fashionable and technological sense.
4.High light cutting
The use of engraving machine will be diamond knife reinforced in the high-speed rotation (general speed of 20,000 rpm) of the engraving machine spindle to cut parts, in the product surface to produce localized highlights area. The brightness of the cutting highlights is affected by the speed of the milling drill, the faster the drill speed, the brighter the cutting highlights, and vice versa, the darker and prone to knife lines. Highlight highlight cutting in the use of cell phones in particular, such as iphone5, in recent years part of the high-end TV metal bezel using a high-gloss milling process, coupled with anodized and brushed process makes the TV set overall full of fashion sense and sharp sense of science and technology.
5.Anodic oxidation
Anodic oxidation refers to the electrochemical oxidation of metals or alloys. Aluminum and its alloys form a layer of oxidized film on aluminum products (anode) due to the action of applied current under the corresponding electrolyte and specific process conditions. Anodic oxidation can not only solve the defects of aluminum surface hardness and abrasion resistance, but also prolong the service life of aluminum and enhance the aesthetics, which has become an indispensable part of aluminum surface treatment, and it is the most widely used and very successful process at present.
6.Double color anode
Two-color anodizing refers to anodizing a product and giving different colors to specific areas. The two-color anodizing process is less used in the TV industry because of the complexity and high cost of the process; however, the contrast between the two colors better reflects the high-end and unique appearance of the product.
Process measures and operating techniques to reduce aluminum machining distortion
Aluminum parts processing deformation of many reasons, and materials, part shape, production conditions and so on have a relationship. There are mainly the following aspects: deformation caused by internal stress in the blank, cutting force, cutting heat caused by deformation, deformation caused by clamping force.
1.Reduce the internal stress of Mao Pei
Internal stresses in the blank can be partially eliminated by natural or artificial aging and vibration treatment. Pre-machining is also an effective process. For fat head and ears of the blank, due to the large margin, so the deformation after processing is also large. If pre-processing off the excess part of the blank, reduce the allowance of each part, not only can reduce the processing deformation of the later process, and pre-processing after placing for a period of time, but also can release part of the internal stress.
2.Improve the cutting ability of the tool
The material and geometric parameters of the tool have an important influence on the cutting force and cutting heat, and the correct selection of the tool is essential to reduce the deformation of the part machining.
(1) Reasonable selection of tool geometry parameters.
①Front angle: under the condition of maintaining the strength of the cutting edge, the front angle is appropriately chosen to be larger, on the one hand, it can sharpen the edge, and on the other hand, it can reduce the cutting deformation, make the chip removal smooth, and then reduce the cutting force and cutting temperature. Do not use negative front angle tool.
② rear angle: the rear angle size of the rear face wear and processing surface quality has a direct impact. Cutting thickness is an important condition for selecting the rear angle. Rough milling, due to large feed, heavy cutting load, heat generation, requiring good tool cooling conditions, therefore, the rear angle should be selected smaller. Precision milling, the requirements of sharp edges, reduce the friction between the rear face and the machined surface, reduce elastic deformation, therefore, the rear angle should be selected larger.
③ Helix angle: In order to make milling smooth and reduce milling force, the helix angle should be chosen as large as possible.
④ Main deflection angle: Appropriate reduction of the main deflection angle can improve the heat dissipation conditions, so that the average temperature of the machining area decreases.
(2) Improvement of tool structure.
① Reduce the number of teeth of milling cutter and increase the chip space. Due to the greater plasticity of aluminum materials, cutting deformation in the processing of large, need a larger chip space, so the bottom radius of the chip slot should be larger, fewer milling cutter teeth is good.
②Precision grinding cutter teeth. Roughness value of the cutting edge of the teeth to be less than Ra = 0.4 um. In the use of new knives before, should use a fine oil stone in front of the teeth, behind the knife gently ground a few times to eliminate the edge of the teeth of the knife when the residual burrs and slight serration pattern. In this way, not only can reduce the cutting heat and cutting deformation is relatively small.
③ Strictly control the standard of tool wear. After the tool wear, the surface roughness of the workpiece increases, the cutting temperature rises, and the deformation of the workpiece increases. Therefore, in addition to the selection of wear-resistant tool materials, tool wear standard should not be greater than 0.2mm, otherwise it is easy to produce chip tumors. When cutting, the temperature of the workpiece should generally not exceed 100 ℃ to prevent deformation.
3、Improve workpiece clamping method
For thin-walled aluminum workpieces with poor rigidity, the following clamping methods can be used to reduce deformation:
① For thin-walled bushing parts, if the three-jaw self-centering chuck or collet chuck is used to clamp from the radial direction, the workpiece is bound to be deformed once it is loosened after machining. At this point, you should use the rigidity of the better axial end face compression method. Positioned in the hole of the part, a threaded self-contained through the center of the shaft, set into the parts of the hole, with a cover plate on the end of the compression face and then backed with a nut tight. Processing of the outer circle can be avoided when the clamping deformation, thus obtaining satisfactory machining accuracy.
② thin-walled sheet workpiece machining, it is best to use vacuum suction cups, in order to obtain a uniform distribution of clamping force, and then a smaller amount of cutting to process, can be very good to prevent deformation of the workpiece.
In addition, the filling method can also be used. In order to increase the rigidity of the process of thin-walled workpieces, the workpiece can be filled with medium inside the workpiece to reduce the clamping and cutting process of the workpiece up to deformation. For example, to the workpiece filled with 3% to 6% potassium nitrate urea melt, after processing, the workpiece will be immersed in water or alcohol, the filler can be dissolved and poured out.
4、Reasonable arrangement of work processes
High-speed cutting, due to the large machining allowance and intermittent cutting, so the milling process often produces vibration, affecting the machining accuracy and surface roughness. Therefore, the CNC high-speed cutting machining process can generally be divided into: roughing – semi-finishing – clear angle machining – finishing and other processes. For parts with high accuracy requirements, it is sometimes necessary to carry out a second semi-finishing process, followed by finishing. After rough machining, the parts can be naturally cooled to eliminate the internal stresses generated by rough machining and reduce deformation. The margin left after rough machining should be larger than the amount of deformation, generally 1 ~ 2 mm. finishing, parts finishing surface to maintain a uniform machining margin, generally 0.2 ~ 0.5 mm is appropriate, so that the tool is in a smooth state in the machining process, you can greatly reduce the cutting deformation, to obtain a good surface finish quality, to ensure the accuracy of the product.
Operational techniques to reduce machining distortion
Aluminum parts material parts deformed during processing, in addition to the above reasons, in practice, the operation method is also very important.
1.For the machining of large parts, in order to make it in the process of machining have better heat dissipation conditions, to avoid heat concentration, processing, it is appropriate to use symmetric processing. If there is a 90mm thick plate needs to be processed to 60mm, if milling a good side immediately after milling the other side, a machining to the final size, then the flatness of 5mm; if the repeated feed symmetric machining, each side of the two times to the final size of the machining, can ensure that the flatness of 0.3mm.
2. If there are more than one cavity on the plate parts, processing, should not be used a cavity a cavity sequence of processing methods, which is likely to cause uneven force and deformation of the parts. The use of multi-layer processing, each layer as far as possible at the same time processing to all the cavities, and then process the next level, so that the parts are uniformly stressed, reducing deformation.
3.By changing the cutting amount to reduce the cutting force, cutting heat. In the three elements of the cutting amount, the back draft has a great impact on the cutting force. If the machining allowance is too large, the cutting force is too large, not only will make the parts deformed, but also affect the rigidity of the machine tool spindle, reduce the durability of the tool. If you reduce the amount of back draft, and will make a big difference in productivity. However, in CNC machining are high-speed milling, can overcome this challenge. In reducing the amount of back draft at the same time, as long as the corresponding increase in feed, increase the speed of the machine tool, you can reduce the cutting force, while ensuring the machining efficiency.
4.The order of tool walking should also be careful. Roughing emphasizes the improvement of processing efficiency, the pursuit of the removal rate per unit of time, generally can be used inverse milling. That is, the fastest speed, the shortest time to excise the excess material on the surface of the blank, the basic formation of the geometric contour required for finishing. And finishing emphasizes the high precision and quality, it is appropriate to use downstream milling. Because the cutting thickness of the cutter teeth gradually decreases from the maximum to zero, the degree of work hardening is greatly reduced, while reducing the degree of deformation of the parts.
5.Thin-walled workpieces in the processing of deformation due to clamping, even if the finishing process is difficult to avoid. In order to minimize the deformation of the workpiece, you can reach the final size in the finishing process before the pressurized pieces of loose, so that the workpiece is free to return to its original state, and then slightly pressed to just be able to clamp the workpiece shall prevail (entirely by feel), so that you can get the desired processing results. In short, the action point of the clamping force is best in the bearing surface, the clamping force should act in the direction of good rigidity of the workpiece, under the premise of ensuring that the workpiece does not loosen, the smaller the clamping force the better.
6. In the processing of parts with cavity, processing cavity try not to let the milling cutter like a drill directly down into the parts, resulting in the milling cutter chip space is not enough, chip removal is not smooth, resulting in parts overheating, expansion, as well as chipping, tool breakage and other unfavorable phenomena. To use the same size as the milling cutter or a larger drill bit to drill down the hole, and then use the milling cutter milling. Alternatively, CAM software can be used to produce a spiral undercut program. […]Read more…

March 19, 20251. What is aluminum alloy?
Aluminum alloy is the most widely used type of nonferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries.
Pure aluminum is divided into two categories: smelting products and pressure-processed products. The former is represented by the chemical composition Al, and the latter is represented by the Chinese pinyin LV (aluminum, industrial use). Aluminum alloys can be divided into two categories according to the processing method: deformation aluminum alloys and casting aluminum alloys.
Characteristics, advantages and disadvantages of aluminum alloy
Compared with commonly used steel materials, aluminum has the following important characteristics and advantages. Based on these characteristics and advantages, aluminum and its alloys are widely used in many fields.
Advantages of Aluminum
1. Aluminum is 3 times lighter than iron.
2. Aluminum has good electrical and thermal conductivity, and is resistant to oxidation. Its thermal conductivity is 16.79 times higher than that of stainless steel, saving fuel and time.
3. Aluminum is a metal with excellent thermal conductivity. It does not rust and is resistant to many forms of corrosion, so products made of aluminum tend to have a much longer service life than products made of other metals, and it also helps reduce the negative impact on the environment.
4. Due to the properties of aluminum products, they are easy to recycle and do not lose their natural properties during the recycling process, which is conducive to environmental protection cycles.
Disadvantages of Aluminum
1.Aluminum has a relatively low hardness and poor wear resistance.
2.The volume shrinkage of aluminum during solidification is relatively large, about 6.6%
3.The linear expansion coefficient of aluminum is relatively high
4.The melting point of aluminum is relatively low, and the use temperature of aluminum and aluminum alloys cannot exceed 200 °C, so its high-temperature use is limited. The elastic modulus of aluminum is only 1/3 of that of steel.
5.The electrode potential of aluminum is very negative, so when aluminum comes into contact with dissimilar metals, it is easy to act as an anode and produce severe galvanic corrosion.
2.Aluminum Alloy Development History
It was not until 1825 that humans first produced a few milligrams of aluminum powder. Aluminum was discovered late, and aluminum smelting technology matured even later. Whether as a metal element discovered by humans or as a structural material, aluminum and its alloys are inferior to other metals. However, the emergence of aluminum and aluminum alloys has greatly promoted the development of industrial civilization, especially aerospace technology and industry.
3.The road to change for aluminum alloys
Aluminum alloy is the most widely used type of non-ferrous metal structural material in industry. It has been widely used in aviation, aerospace, automobiles, consumer electronics, machinery manufacturing, shipbuilding and chemical industries. The following will introduce the transformation of aluminum alloy from the fields of aviation, aerospace, automobiles, consumer electronics, etc.
Aerospace “Aluminum” Analysis of the Development Stages of Aviation Aluminum Alloys
Aviation aluminum is a kind of ultra-high strength deformable aluminum alloy, which is currently widely used in the aviation industry. It has good mechanical and processing properties, good plasticity after solution treatment, good heat treatment strengthening effect, generally has high strength and good toughness below 150°C (or even higher), and is an ideal structural material. In addition, aviation aluminum is light in weight and has a significant lightweight effect. It has replaced steel and occupies a dominant position in current aviation materials. Aviation equipment has high requirements for aluminum and is an important high-end application market for aluminum.
Advantages of Aluminum for Aviation
Application advantages: Aluminum alloy will also be the main structural material for domestic large aircraft development due to its high specific strength, good forming and processing performance.
Application parts: wing skin, wing long stringer, upper and lower edge strips of wing beam, web, fuselage long stringer, seat slide rail, keel beam, side frame, fuselage skin, lower fuselage wall panel, main floor stringer, etc.
Application proportion: A380-800 Airbus aluminum alloy material accounts for the largest proportion, reaching 61%, A350-900XWB Airbus aluminum alloy material accounts for 20%, Boeing 787-8 Airbus aluminum alloy material accounts for 15%-20%.
Commonly used aluminum alloy series
The aluminum alloys used in large aircraft structures in various countries around the world today are mainly high-strength 2××× series (2024, 2224, 2324, 2424, 2524, etc.) and ultra-high-strength 7××× series (7075, 7475, 7050, 7150, 7055, 7085).
Development direction of aluminum for aviation
The future research focus of aluminum alloys will be mainly on the following aspects: aluminum-lithium alloys, aluminum-based composite materials and superplastic forming aluminum alloys.
Aluminum-lithium alloy
Aluminum-lithium alloy is a multi-component aluminum alloy containing lithium. Lithium is the lightest metal element. For every 1% increase in lithium in aluminum alloy, the density can be reduced by 3% and the modulus can be increased by 5%. In addition to the advantages of light weight, high modulus and high strength, aluminum-lithium alloy also has excellent fatigue resistance and good low-temperature toughness. Its strength is comparable to that of 2024, 7075 and other aluminum alloys. In view of this, aluminum-lithium alloy has been deeply loved by the aerospace industry. As a new type of aerospace structural material, it has become a hot spot for developed countries such as the United States, Britain, France and Russia to compete for research and development.
Aluminum-based composite materials
Aluminum-based composite materials have attracted widespread attention due to their many advantages, such as low density, high specific strength and specific stiffness, large specific elastic modulus, good electrical and thermal conductivity, high temperature resistance, oxidation resistance, corrosion resistance, and flexible preparation process.
For a long time, aluminum-based composite materials have been used in a variety of ways, such as complex preparation process, strict requirements on environment and equipment, and high cost.
Superplastic forming of aluminum alloys
Superplastic forming of aluminum alloy is achieved by deformation heat treatment to obtain ultrafine grains less than 10μm. These ultrafine grain alloys can obtain superplasticity above the semi-melting point and at low strain rate conditions, and can be formed into light-weight, low-cost, and complex-shaped components that are difficult to obtain by traditional methods. They also have many advantages such as low forming pressure, high mold life, and one-time precision forming.
Analysis of “Aluminum” in Consumer Electronics Development Stages of Aluminum Alloys in Consumer Electronics
Aluminum alloy is the most common nonferrous metal product. Among them, the ones that are most closely related to us are aluminum products for consumer electronic appliances. Aluminum alloy is mainly reflected in consumer electronic products in the form of casings, frames, radiators and aluminum tubes.
Market Analysis of Aluminum for Consumer Electronics
At present, the scale of the consumer electronics market has entered a stable development stage. In mature markets, second-time purchases have become the mainstream. Consumers and consumer electronics companies are paying more and more attention to the appearance design and material technology of products.
The White Paper on Aluminum Use in China’s Consumer Electronics Industry (2016) shows that the sample companies used nearly 20,000 tons of aluminum in the finished products sold in the domestic consumer goods market in 2016, a year-on-year increase of nearly 35%, much higher than the growth rate of the consumer electronics market in the same period.
It is estimated that in 2016, the domestic demand for aluminum in the four consumer electronics fields of mobile phones, tablets, mobile power supplies, and televisions will be about 120,000 tons, and it is expected to increase to nearly 20 tons in 2018.
Aluminum Rising Star for Consumer Electronics – 7075 Alloy
The “bending gate” of iPhone 6 plus broke the hearts of a generation of Apple fans. In order to solve the problem of low bending resistance of iPhone 6 plus, the aluminum industry suggested that Apple use the ultra-high-strength aluminum alloy 7075 plates used in the aerospace industry to process the body. Both iPhone 6S and iPhone 6S plus were manufactured using 7075 alloy plates produced by Alcoa, achieving the expected good results. The bending resistance was greatly improved, and the problem of bending due to a fall disappeared, and deformation did not occur.
7075 Alloy Introduction
The 7075 alloy was developed by the American Aluminum Company for World War II aircraft and was used to manufacture large bombers and fighters. It was finalized in 1944 and the grade before July 1954 was 75S. In July 1954, it was registered with the American Aluminum Association and changed to a unified four-digit grade 7075.
For example, the front fuselage long stringer, passenger observation window frame, middle fuselage long stringer, keel beam edge strip, keel beam web, floor turning beam, middle and rear fuselage long stringer and cargo door frame, nose long stringer and edge strip, cabin door frame, etc. of the C919 aircraft are all made of different 7075 alloy materials. It can be said that without the support of 7075 aluminum alloy, such a high-value, lighter, more comfortable and faster large passenger aircraft cannot be built.
Application of 7075 alloy in mobile phone industry
The new iPhone is not the only smart phone that uses this super-strong material in the world’s mobile phone body. The ultra-thin bodies of Samsung’s Note5 and S6 edge+ benefit from the use of 7075 alloy. Due to the excellent performance of 7075 alloy, the stability of the bodies of the two smart phones has reached an unprecedented new height. Since then, there has been no bending or damage.
Mobile phones and electronic products: The shortcomings of aluminum shells need to be fully addressed
There are many kinds of electronic products, and the aluminum materials used are also varied, with styles that vary greatly. Although the amount of a single product is not much, the output of electronic products is large, in the millions, tens of millions, and even hundreds of millions, and the replacement is very fast. Aluminum is widely used in the manufacture of mobile phone bodies and electronic product shells. Now it is almost impossible to find electronic products that do not use aluminum.
At present and in the future, the trend of thinner and lighter mobile phones is an unstoppable trend, which requires stronger and better body materials to support it. In the future, more domestic mobile phones will definitely use 7xxx series alloy thick plates as body materials, but the plates used now are all produced by Alcoa, and the import price is as high as 70,000 yuan/t, which is about 3.9 times the price of 3xxx series alloys. In addition to the fact that the production process of 7075 alloy is much more complicated than that of other alloys, foreign companies have also seen that China cannot currently produce aluminum alloy thick plates of this type of mobile phone grade, and rare goods are in great demand.
Therefore, China must get rid of this dilemma as soon as possible and make up for this shortcoming. China’s aluminum processing equipment is fully capable of producing this kind of aluminum plate. In fact, as early as 1957, Harbin Aluminum Processing (code-0-Factory, now Northeast Light Alloy Co., Ltd.) successfully trial-produced aviation-grade B95 (Soviet brand, equivalent to 7075) alloy materials with the help of Soviet experts.
Of course, the processing technology of 7xxx alloy mobile phone body alloy plates, including CNC cutting and anodizing coloring, is much more difficult than 6xxx series alloy plates. Whether these problems can be solved smoothly will be the key to whether the alloy plates can be promoted and applied in domestic mobile phones.
“Aluminum” in the automotive industry: Analysis of the development stages of aluminum alloys for automobiles
The development of energy-saving and environmentally friendly cars is an urgent need to ease the contradiction of fuel supply and reduce exhaust emissions. It is also an inevitable choice for the sustainable and healthy development of my country’s automobile industry in the future. As a common key technology for energy-saving cars and new energy vehicles, automobile lightweighting has also been widely promoted and applied.
The development of the world’s automobile industry faces three major themes: energy saving, environmental protection and safety. According to the test verification of relevant research institutions, a 10% weight reduction of gasoline passenger cars can reduce fuel consumption by 3.3%, and a 15% weight reduction can reduce fuel consumption by 5% accordingly.
Lightweighting of the body is an inevitable choice for new energy vehicles to increase the “range” by increasing the number of battery packs. With the rapid development and popularization of new energy vehicles, lightweighting of the body has also received more and more attention. Advanced high-strength steel, aluminum-magnesium light metal, carbon fiber and other composite materials have become the three main directions of lightweight development.
Application of aluminum alloy in automobiles
Aluminum alloys are widely used in automobiles. Power and transmission systems, body and interior and exterior systems, heat exchange systems, wheels, etc. all have parts made of aluminum alloy materials.
With the development of lightweight automobiles, the rapid growth of aluminum alloy applications in the future will mainly focus on body structural parts such as panels and body-in-white. The proportion of all-aluminum bodies will increase from the current 4% to 18%, with an average annual compound growth rate of more than 16%.
By 2025, the proportion of models with all-aluminum bodies will reach 30%, the total amount of aluminum used in global car bodies will reach 8.7 million tons, and the aluminum industry for car bodies will experience explosive growth.
New directions in the research, development and application of automotive aluminum
With the increasing degree of automobile aluminumization, it is required to develop new aluminum alloys for different purposes and new aluminum materials of different specifications and varieties. This will greatly promote the development of aluminum alloys and their processing technology, and promote the application of aluminum materials in the automobile industry. It can be foreseen that aluminum materials will partially replace steel and become the basic material of the automobile industry. The expansion of automobile aluminumization in the future will inevitably rely on the balance between the demand for aluminum materials and the production cost. Reducing the cost of aluminum materials and improving production efficiency are the future directions of efforts:
1. Research and development of new aluminum alloy body materials
2. Research and development of anti-collision guards and rigid door structural parts
3. Research and development trends of rotating parts
4. Research and development of new aluminum alloy heat exchange materials
5. Research and development of weldable medium-strength aluminum alloy plates for commercial vehicle fuel tanks and air compressor cylinders
6. Research and development of forged aluminum alloy wheels and structural parts

March 6, 2025Today, aluminum has rapidly developed into an indispensable material in the lives of every Chinese. Aluminum alloy doors and windows, aluminum alloy furniture, bathroom appliances, cooking utensils, household appliances in Chinese homes, all means of transportation used for travel, such as bicycles, electric vehicles, motorcycles, cars, high-speed trains, airplanes, ships, computers and mobile phones used in daily work and life, etc., all use aluminum to varying degrees, and the application of aluminum is constantly expanding.
It is precisely because of the huge demand for aluminum among 1.38 billion Chinese that my country’s aluminum industry has leaped to the top of the world in just over 20 years (the rapid development of my country’s aluminum industry began in 1991). At present, China’s demand for bauxite, production and consumption of alumina, production and consumption of electrolytic aluminum, and production and consumption of aluminum materials have all leapt to the top in the world, and have exceeded the total production and consumption of all developed countries. At the same time, it has also created world alumina and electrolytic aluminum production giants such as Weiqiao, and created world aluminum alloy rod production giants such as Innovation. Reform and opening up have provided broad space for the development of my country’s aluminum industry.
The technology and equipment achievements accumulated by foreign aluminum companies that have worked hard in the aluminum industry for more than 120 years have given wings to the development of China’s aluminum industry, which has enabled China’s aluminum industry to complete the journey that foreign aluminum industries have taken more than 120 years to complete in just over 20 years.
1.Discovery and utilization of bauxite
Bauxite is the best raw material for producing aluminum, accounting for more than 90% of the world’s total bauxite production. Bauxite was first discovered by French geologists in 1821. To produce aluminum from bauxite, alumina must first be produced, and then aluminum is produced by electrolysis. Bauxite mining began in France in 1873, and the production of alumina from bauxite began in 1894, using the Bayer process. By 1900, there was a small amount of bauxite mining in countries such as France, Italy and the United States, with an annual output of only 90,000 tons.
With the development of modern industry, aluminum as a metal and alloy has been applied to aviation and military industries, and then expanded to civilian industries. Since then, the aluminum industry has developed rapidly. By 2016, the world’s electrolytic aluminum production has reached more than 57 million tons, and the mined bauxite in 2016 increased to 262 million tons. According to the data of the U.S. Bureau of Mines in 2017, the world’s bauxite reserves are 28 billion tons. The bauxite resources given by the earth to mankind provide raw materials for the world and China’s aluminum industry.
2.Bayer process for producing alumina
The Bayer process is a widely used industrial method for producing alumina from bauxite. It was invented by Austrian engineer Bayer in 1887. Currently, 95% of the world’s alumina companies use the Bayer process to produce alumina.
3.Hall-Heroult process for producing electrolytic aluminum
In 1886, American Hall and Frenchman Heroux independently invented the cryolite-alumina molten salt electrolysis method to produce aluminum. So far, all the aluminum in the world is produced by electrolysis.
4.Aluminum alloy melting
Melting is a method of alloying metals. It is a process that changes the physical state of metals by heating, so that the base metal and alloying components are melted into a uniform melt according to the required ratio, and meet the internal purity, casting temperature and other specific requirements. The quality of the melt has a decisive influence on the processing performance and final use performance of aluminum materials. If the quality of the melt is inherently insufficient, it will bring potential dangers to the use of the product. Therefore, melting is a key process that plays a dominant role in the quality of processed products.
5.Aluminum melt processing technology
Inclusions and hydrogen content in metals have significant adverse effects on the strength, fatigue resistance, corrosion resistance, stress corrosion cracking performance and processing performance of materials. Effectively controlling the hydrogen content and oxidized inclusion content of the melt to improve the quality of cast bars and rolled plates has become a common goal pursued by metallurgy, casting and materials industries in various countries. At present, electromagnetic stirring, refining in the furnace, online deterioration outside the furnace, online degassing and online filtration methods are widely used to reduce the hydrogen content and inclusion content in the aluminum alloy melt and improve the mechanical properties and appearance quality of the ingot.
6.Direct water-cooled ingot
Aluminum Corporation of America invented the technology of direct water-cooled casting, which was adopted by all Aluminum plants in the 1930s. In the 1950s, ingots cast by direct water-cooled casting could be used to manufacture large products required by the aerospace, shipbuilding and transportation industries. With the advancement of direct water-cooled casting technology and equipment, the size of ingots has been continuously increased. Currently, slabs can weigh up to 45 tons and the diameter of aluminum bars for extrusion can reach 1.2 meters.
7.Aluminum machining and die casting
Aluminum processing is to process aluminum billets into materials by plastic processing methods. The main methods include rolling, extrusion, stretching and forging. Among aluminum and aluminum alloy processed materials, rolled materials (plates, strips, bars, foils) and extruded materials (tubes, bars, profiles, wires) are the most widely used and have the largest output. According to statistics, the annual output of these two types of materials accounts for about 58% and 39% of the world’s total annual output of aluminum (on average), respectively. The rest of the aluminum processed materials, such as forged products, only account for a few percent of the total aluminum output.
Pressure casting, also known as die casting, is a casting method that pours molten alloy liquid into a pressure chamber, fills the cavity of a steel mold at high speed, and solidifies the alloy liquid under pressure to form a casting. Die casting machines, die casting alloys and die casting molds are the three major elements of die casting production, and none of them can be missing. The so-called die casting process is to organically combine these three major elements to produce qualified castings with good appearance and internal quality and dimensions that meet the requirements of drawings or agreements in a stable, rhythmic and efficient manner.
8.Heat treatable aluminum alloy
In 1908, German scientists discovered the aging strengthening phenomenon of aluminum-copper-magnesium alloys, which greatly improved the strength of aluminum alloys and expanded the application areas of aluminum alloys.
New alloys are constantly being developed by various countries. At present, there are 680 deformed aluminum alloys registered by the Aluminum Association of America. Among them, the most used is the 6063 aluminum alloy in the aluminum-magnesium-silicon system registered by the American Aluminum Company in 1954.
9.Aluminum surface treatment technology
In the past sixty years, the surface treatment technology of aluminum products has developed rapidly. After surface treatment, aluminum alloy products give people a very beautiful and exquisite appearance. Chemical conversion film treatment is one of our most common surface treatment technologies. Anodizing, composite anodizing, micro-arc oxidation, electrophoretic painting, etc. are all chemical conversion film treatments. Chemical conversion film treatment is more mature and stable than other surface treatment technologies. But now more composite technology is used. Composite technology is to combine the advantages of various technologies and avoid their disadvantages. Such as arc glow technology, ion beam combined sputtering technology, etc., ion beam combined sputtering technology combines magnetron sputtering with ion implantation, ion sputtering has the advantages of fast speed, low temperature, good bonding strength, etc. There is also a combination of laser and sputtering.
10.Environmental protection technology in the aluminum industry
The main pollutants in the aluminum industry include red mud produced during the production of alumina, fluorine-containing waste gas from electrolysis, flue gas from carbon calcination and roasting, waste from electrolytic cell overhaul, waste water and waste oil from aluminum processing, and other industrial wastes. These waste slag, waste gas, and waste water have always been the focus of environmental monitoring, and are related to occupational health and safety and social, ecological, and economic sustainable development.
In order to enable the aluminum industry to continue to develop in the direction of green and low carbonization, corresponding environmental protection and energy-saving equipment has been continuously developed, striving to improve the overall environmental protection level of the aluminum industry from various aspects such as environmental protection, intelligence, and integrated control.
While enjoying the technological and equipment achievements of the world’s aluminum industry, every aluminum-related company at home and abroad has also made contributions of varying sizes to the development of the aluminum industry.

February 6, 2025Extrusion process
Aluminum extrusion (or aluminum extrusion molding) is defined as the aluminum billet placed in the die cavity (or extrusion cylinder) to apply strong pressure, forcing the aluminum billet to produce directional plastic deformation, extrusion from the extrusion die holes, so as to obtain the required cross-section shape, size and mechanical properties of the parts or semi-finished products of the plastic processing methods. Its working principle is similar to “squeezing toothpaste”. This metal molding method has the following significant advantages.
1.Long-lasting
Aluminum’s resistance to corrosion, erosion and weathering is one of its most significant advantages. Aluminum naturally rusts and resists corrosion without additional treatment. This is due to the presence of a thin, naturally occurring protective film of aluminum oxide on its surface. By anodizing, its resistance to corrosion becomes even stronger. For example, in outdoor environments, anodizing can be performed to 25 microns, which increases corrosion resistance and improves surface finish. In addition, aluminum requires no maintenance and in most cases can be used without fear of corrosion.
2.lightweight and sturdy
Aluminum is over 33% lighter than steel while retaining most of its strength. Most aluminum alloys have a tensile strength range of about 70-700 MPa and are two-thirds less dense than steel. Product design engineers don’t have to worry about the strength of extruded aluminum parts, and it can be used as a structural component in the construction industry as well as in the automotive industry, making it an excellent alternative to other metal materials. The automotive industry is making significant use of aluminum alloys in order to lighten weight and reduce energy consumption.
3.Good thermal conductivity
Aluminum has very similar thermal conductivity to copper, but is much lighter in weight. Aluminum is an excellent conductor of heat, and the contours of the aluminum extrusion are designed to maximize the surface area for thermal conductivity and the formation of thermal pathways. A typical example is a computer CPU cooler, where aluminum is used to carry heat away from the CPU.
4.Stylish appearance
Extruded aluminum can be painted, plated, polished, and anodized, giving engineers a wider range of appearance options than other materials.
5.Wide range of applications
Basically any cross-section shape can be formed by aluminum extrusion, so aluminum extrusion has a wide range of applications and engineers can design different cross sections to meet the requirements of different application environments.
6.Convenient for secondary processing
Aluminum extrusions can be easily formed, cut, drilled, machined, stamped, bent and welded to suit specific purposes.
7.Short cycle time and low cost for mold processing
Aluminum extrusion has simple tooling and short, inexpensive processing cycles. This is AEC’s comparison of aluminum extrusion and other metal forming processes for reference only.
8.Shock and deformation absorption
In construction, aluminum extrusions resist deformation caused by weather and building movement. In transportation, they absorb impact energy. Aluminum extrusions maintain strength and flexibility under load and rebound from impact.
9.Environmentally friendly
Aluminum is an environmentally friendly material, easy to recycle. In short, aluminum is the metal of the future with its irreplaceable advantages. It is not only environmentally friendly, lightweight, naturally corrosion-resistant and strong, but also conducts heat and electricity well.
Extruder construction
1.Extruder structure of the main three major parts
The extruder structure is mainly composed of three main parts: mechanical part, hydraulic part and electrical part. The mechanical part consists of base, pre-stressed frame tension column, front beam, movable beam, X-type guided extrusion cylinder seat, extrusion shaft, ingot supplying mechanism, residue separation shear, sliding die holder and so on. Hydraulic system mainly consists of main cylinder, side cylinder, locking cylinder, piercing cylinder, large-capacity axial piston variable pump, electro-hydraulic ratio servo valve (or electro-hydraulic proportional control valve), position sensor, oil pipe, oil tank and various hydraulic switches. The electrical part is mainly composed of power supply cabinet, operation desk, PLC programmable controller, upper industrial control machine and display screen.
2.Extruders are categorized into single-acting and double-acting extruders according to their structure
The single-action aluminum extruder extrudes by advancing the main cylinder and pressing the aluminum bar toward the die through the extrusion cake, thus forming the shape. The round tubes extruded by single-action extruder have seams, which can only be detected with instruments. Double-action extruder, hydraulic oil through the filling valve to fill the main hydraulic cylinder, pushing the main plunger forward ( the front of the main plunger is connected to the moving beam, moving beam mounted on the extrusion shaft ), to realize the extrusion action . The main plunger is also the perforating cylinder. When piercing, the piercing plunger moves forward (the piercing needle is installed at the front end) to realize the piercing action. Since the main plunger and perforating plunger can operate independently of each other, they are two actions, so they are called double-action extruders.
3.According to the form of extrusion, it is divided into forward extruder, reverse extruder and forward and reverse extruder
Forward extrusion is relatively simple and corresponds to the direct transfer of the extrusion force to the billet. The direction of metal flow is the same as the direction of advancement of the extrusion rod, which is the basic characteristic of this extrusion method. Compared with forward extrusion, thanks to the special material flow characteristics of reverse extrusion (no friction between the bar and the inner wall of the extrusion cylinder), the material flow is more homogeneous, so the extrusion speed is faster, because the bar tends to be longer, so the pressure balance is thinner, which means higher production efficiency. At the same time, reverse extrusion products along the longitudinal direction of the temperature rise is very small, the average temperature is also low, in product quality can ensure good dimensional accuracy. Reverse extrusion and its short-stroke design can be equipped with or without a piercing device. Therefore, reverse extrusion is currently the most efficient form of extrusion for pipe and bar production.
Extruder Selection
(1) Choose according to the characteristics of the extruded alloy. For example, extruding 6063-T5 industrial aluminum profiles, you can choose positive single-action horizontal extruder; extruding soft alloy tubes, you can choose positive double-action horizontal extruder.
(2) In the production of high-precision industrial profiles, the choice of high-performance, low-consumption, high-efficiency automated extruder. For example, the industry’s mainstream short-stroke, high-speed front loading extruder, has many advantages. For example, the stacked tensioning post / outer sleeve design and the finite element optimized machine body ensure a longer service life. At the same time, the main components such as the front beam, the extrusion cylinder and the master cylinder have a higher frame rigidity. The front loading ensures that the barrel can be loaded by moving it forward with no friction between the bar and the barrel, and the symmetrical upsetting improves the venting effect of the barrel.
(3) Selection according to the specific extrusion capacity. The size of the extrusion capacity should be calculated, according to their own production conditions, technical level, equipment conditions and sales conditions as the basis for calculating the annual production time, the amount of work per hour and other parameters to calculate the annual production capacity of the extruder, because the size of the output and the size of the cross-section to determine the choice of which extruder, different alloy compositions required for the extrusion capacity is also not the same, the extrusion pressure of the ordinary aluminum extruder is 250MPa ~ 400MPa, the extrusion pressure is 250MPa ~ 400MPa, the extrusion pressure is 250MPa ~ 400MPa. The extrusion pressure required for ordinary aluminum profiles is 250MPa~400MPa, the extrusion pressure required for hollow aluminum profiles is 450MPa~1000MPa, and the extrusion pressure required for pure aluminum extrusion is smaller, 150MPa~250MPa. The extrusion methods are also very different, and the extrusion pressure required for forward extrusion is 1/3 larger than that required for reverse extrusion.
(4) According to the actual financial situation of the user and product positioning to choose. If the enterprise production of aluminum products for low-grade, you can choose domestic extruder; if it is positioned as a high-grade products, we must choose to import the extruder. Regardless of which grade of extruder, according to their own actual conditions to determine, if only the production of low-grade aluminum products, there is no need to choose foreign imports of extruders, on the one hand, the amount of investment is larger, on the other hand, for the maintenance of the later is also a very difficult thing, after all, all aspects of the cost will be increased, but also affects the progress of the production, to be able to live within their means, all-round considerations.
(5) in accordance with the manufacturer’s pre-planning and design, as far as possible, the use of standard equipment, equipment to save space, personnel savings, shorten the preparation cycle of production technology. For example, you can choose a new type of compact extruder, this new concept will be forged front beam of the extruder installed at one end of the extruder, the other end is forged main column cylinder, equipped with a balancing tank, to achieve a new hydraulic concept. With this concept, the position of the main tank becomes more flexible, thus making it unnecessary to mount it above the rear beam. This construction optimizes the geometry of the cast frame, resulting in a very compact extruder structure.
(6) Whether the extrusion press manufacturer can provide colleges and universities, strong technical support, staff training, technical support, so that the customer in the latter part of the production of smooth and worry-free. Strong after-sales service network is also a top priority when choosing, only perfect after-sales service, is a strong backing for manufacturing.
Future Technology Trends
1. Further increase in equipment squeezing force
When equipment has more extrusion force, it means further breakthroughs in the limitations of the current aluminum extrusion process, which opens up a wider world for the creation of new aluminum products and even the manufacture of new materials. In addition, higher extrusion pressures result in more efficient extrusion cycles, which in turn increase the existing capacity and mean better economy. In order to achieve this, the rigidity and structural design of the extruder frame needs to be continuously improved to withstand the stronger extrusion pre-stress. The latest technology from overseas is the 160 MN extruder from SMS, which uses a CF frame that is not only compact, but also optimizes the geometry of the cast frame, thus significantly improving the frame structure and component stiffness of the machine. In addition, the machine utilizes laminated tensioning columns (with external pressure sleeve), a cascade design that provides a lower notch factor than conventional screw-retained tensioning columns. At the same time, precise adjustment by means of separate hydraulic cylinders achieves greater stiffness and pre-stress handling. This design offers many advantages such as no wear, long life, no adjustments, low friction, very high impact resistance (overload), etc.
2.Energy and Operational Efficiency
(1) Energy efficiency. In order to further improve the economy, the optimization of energy-saving technologies for each part of the extrusion equipment will be the key in the future. The following is only an example of energy saving in the pumping station of the extruder. For example, the Italian company Danieli relies on its self-developed ESED4.0 intelligent pumping station energy-saving system, which has become the most advanced energy-saving management program in the industry. The system through the quantitative pump with variable frequency drive technology, so that during the extrusion process, only the required number of pumps to start, and then realize the precise control and the number of working pumps ratios, which will only open the number of hydraulic pumps required in the current extrusion speed, thus reducing the additional and unnecessary report of the pump group loss. At the same time, the system offers significant efficiency gains, such as a 30% increase in pump displacement through variable frequency drive of the dosing pumps. In short, the system’s economy can be reflected in the following two aspects: (1) investment: 10% reduction in hydraulic costs, 20% reduction in piping, the main pump low noise. ②Operation: Reduced overall maintenance costs and shorter non-extrusion cycle.
(2) Improvement of operation efficiency and more intelligent equipment operation. In terms of the theme of creating economical equipment, we will have to consider further improving the operating efficiency of the extruder in the future.

January 22, 2025Elimination of tax rebates on aluminum exports. It is not an exaggeration to say that China’s announcement made the world tremble.
On November 15, the Ministry of Finance and the State Administration of Taxation issued an announcement that since December 1 this year, the export tax rebate for aluminum and other products will be abolished, and the aluminum products involved almost cover the main aluminum profiles, aluminum sheet and strip foils, aluminum bars and rods and other aluminum products.
As of now, China is the undisputed absolute hegemon of the global aluminum industry, and China’s aluminum exports reached 5.287 million tons in 2023, accounting for about 35% of the total global trade.
In terms of production, China’s absolute dominance is even more terrifying, in which primary aluminum production accounts for 59% of the world, aluminum production accounts for about 66%, electrolytic aluminum accounts for 60%, and smelted aluminum is also close to 60%.
According to statistics from the United States Geological Survey (USGS), China’s smelting aluminum production in 2023 will be ten times that of the second-ranked India, and the total production of other countries in the world is only 70% of China’s.
As an extremely important basic resource, aluminum products play a key role in industries such as construction, rail transit, automobiles, and cables. Due to the super status of Chinese aluminum products in the world, countries around the world can hardly bypass China when using aluminum products.
Even though the United States has imposed various trade measures such as anti-dumping duties, countervailing duties and tariffs on my country in recent years, it remains the world’s largest buyer of Chinese aluminum products and the world’s largest importer of aluminum to this day.
The aluminum industry chain, especially electrolytic aluminum, is a “power-eating behemoth” with a huge appetite, which seriously restricts the development of the aluminum industry in other countries and regions. Based on my country’s aluminum exports last year, at least 740GW of electricity was consumed. By the end of September this year, my country’s total photovoltaic installed capacity had reached this figure.
Due to geopolitical conflicts and the pursuit of reducing carbon emissions by mainstream countries around the world, the power supply is insufficient and the energy crisis has emerged. The electricity left for electrolytic aluminum will only become less and less. China’s reduction in aluminum exports will mean a large number of chain reactions for countries around the world, and a subsequent reassessment of China’s industrial capabilities.
1.Electricity-Eating Monster
Aluminum was once more precious than gold.
Aluminum was a very rare metal more than a hundred years ago due to the difficulty of refining. In order to show his lofty status, Napoleon III specially made an aluminum crown, and only he could use exclusive aluminum tableware, and others could not. Only gold or silver cutlery may be used.
Aluminum itself is the most abundant metal element in the earth’s crust. It was not until 1889 that Austrian scientist Bayer invented a method of extracting aluminum oxide from bauxite, and then invented the electrolytic production method, which officially opened the prelude to the large-scale industrialization of aluminum. Currently, almost all aluminum companies in the world use the “Bayer process”.
The efficiency of aluminum smelting has been greatly improved, but the disadvantage of electrolytic aluminum is that it consumes huge amounts of electricity, making it a “power-consuming monster.” It takes 13,600 kw/h of direct current (nearly 14,000 degrees) to produce one ton of electrolytic aluminum. Once upon a time, my country had to use more than 7% of its annual electricity to produce electrolytic aluminum. This was just one link in the electrolytic aluminum industry. The electricity consumption of the entire industry chain was an extremely huge number.
In 2023, the national production of 41.513 million tons of electrolytic aluminum, this calculation, power consumption of up to 564.6 billion kWh of electricity, equivalent to 5646GW, last year’s aluminum exports of 5.287 million tons of power consumption close to 740GW.
To know, at the end of last year, China’s cumulative installed capacity of photovoltaic power generation is less than 610GW, the global cumulative capacity of 1546GW. to June this year, China’s photovoltaic cumulative total of 713.5GW, as of the end of September, only to reach 770GW, that is to say, just China’s exports of aluminum will need to be powered by all of the photovoltaic in China.
At the end of last year, Europe’s cumulative installed capacity of photovoltaic climbed to 263GW, the United States 162GW, India has just exceeded 60GW. relying only on photovoltaic clean energy, the gap is very huge.
Aluminum electrolysis at the same time is still a high-emission industry, smelting process carbon emissions had accounted for about 5% of China’s total carbon emissions, second only to steel and cement. Such a huge amount of carbon emissions is unaffordable for any country pursuing a green energy transition.
In November 2018, the European Union proposed to achieve carbon neutrality by 2050, and has since further established a target of 55% emission reduction (compared to 1990) for member states by 2030; the United States plans to reduce greenhouse gas emissions to half of the 2005 level by 2030, and to achieve “net-zero” emissions by 2050. “emissions by 2050.
Of course, this goal may become recurring as new administrations come to power.
That’s why India, the world’s second-largest aluminum producer, is the world’s third-largest carbon emitter after China and the United States. In order to realize the completion of 500GW of clean energy in 2030, India is frantically mounting photovoltaic projects, and in the first half of 2024, its photovoltaic new installations of 14.9GW, a year-on-year surge of 282%, a record high for the same period in history.
And China is the world’s top PV country, with a complete whole industry chain absolute advantage, India 80% of PV components rely on Chinese manufacturing.
Have no choice, there is news that even India’s second largest aluminum group Indian Aluminum Industries has begun planning to enter the field of solar modules. The company also at the end of last year, plans to invest 80 billion rupees to establish a battery foil manufacturing plant.
Therefore, China’s tightening of aluminum exports this announcement, so that the world vibration, will pay more attention to China’s industrial capacity, whether it is traditional industrial products or photovoltaic, wind power and other new energy products.
2.The world can’t do without Aluminum China
Countries around the world are basically dependent on Chinese aluminum products.
Based on its huge scale advantage, Chinese aluminum products are making inroads into the world.
Especially the United States. Even though it has introduced various trade restrictions, it is still the largest buyer of Chinese aluminum products.
As early as 2018, the United States initiated a 301 tariff review of China, involving 33 sub-divisions of aluminum products; in October 2023, the U.S. Department of Commerce announced that it had imposed a preliminary anti-dumping duty of 167.16% on China’s ordinary aluminum alloy plates, 59.31% on China’s aluminum profiles, and a countervailing duty rate of up to 137.65% on Chinese companies involved in the case;
September 13 this year, the United States and decided to China’s exports of electric vehicle batteries, key minerals, steel, aluminum, masks and other products, the tariff rate will be raised to 25%.
The rounds of tax increases, almost all of the aluminum is covered. It can be said that the United States of China’s aluminum products for a full range of non-discriminatory “comprehensive blow”. But because the United States is extremely dependent on aluminum imports, to 2023, the United States is still China’s largest export market for aluminum products, exports to the United States totaled 694,000 tons, exports of 3.79 billion U.S. dollars.
Due to the continued increase in demand from the automotive lightweight, rail transportation and other industries, Goldman Sachs expects the global aluminum market will also see a shortfall of 7.24 million tons this year.
However, due to the constraints of zero carbon emission targets, China’s electrolytic aluminum has been close to the ceiling of compliance capacity. Some brokerage calculations, electrolytic aluminum compliance capacity limit value of 44.67 million tons, the expansion of space has been little.
According to the previous departments to clean up and rectify the electrolytic aluminum illegal and irregular special action provisions, where the electrolysis process contains the project, must be implemented electrolytic aluminum capacity replacement, that is, “the construction of electrolytic tanks, must be replaced”.
Overseas, in Russia played “cut off” king bomb, Norway Hydro decided to close Slovakia aluminum smelter, Germany’s large aluminum rolling company Speira announced a cut of its German smelter half of the production capacity of Europe’s largest aluminum smelter France Dunkirk Aluminum also said that the production reduction of 22%.
By incomplete statistics, the overseas capacity closure in 2022-2023 is as high as 1.581 million tons, superimposed on the impact of dual-carbon policy and energy issues, further production cuts are more likely.
In fact, the main force of new overseas production capacity or Chinese enterprises, Huaqing Aluminum, Huayou Holdings, Nanshan Aluminum, Shandong Weiqiao / China Liqin and other overseas investment and construction of up to 6,050,000 tons of production capacity scale, the new production capacity of aluminum enterprises in other countries is only 714,000 tons, but also face a lot of uncertainty.
In order to bypass the trade sanctions in Europe and the United States and other countries, China’s aluminum companies also accelerated overseas production, especially Indonesia landed a number of projects, superimposed on the rebound in aluminum prices, the domestic aluminum company performance, Nanshan Aluminum industry in the first three quarters to achieve a net profit of 3.49 billion yuan, an increase of 62.94%; Aluminum Corporation of China in the first three quarters of the ho earned 9.017 billion yuan, an increase of 68.46%; China Hongqiao first half of the storm earned 9.155 billion yuan, a jump of 2.7%. billion yuan, a year-on-year surge of 2.7 times.
At present, the world’s top fifteen electrolytic aluminum producers, China alone accounted for seven seats, respectively, Chinalco, Hongqiao, Xinfa, Guodian Investment, Oriental Hope, Jiujiang Steel and Shenhuo, production accounted for 37% of the global total.
And Alcoa (Alcoa) due to soaring energy and other costs, sustained losses since 2022, after the permanent closure of the Intalco aluminum smelter located in Washington State, production has withdrawn from the world’s top ten.
The crisis of the United States and European aluminum companies, the United States of America’s dependence on Chinese aluminum products will further deepen.
3.The bottom line of industrial scale
The global aluminum industry landscape is solid.
The huge scale of the aluminum industry allows China to hold ample trade leverage, allied with the South in one hand and exported to developed countries in the other.
China’s aluminum manufacturing capacity dominates the world, but its upstream resources rely heavily on overseas imports. China’s bauxite and alumina reserves account for only 2% of the world’s total, and currently around 70% of bauxite needs to be imported.
The world’s bauxite is concentrated in Guinea, Vietnam, Australia, Brazil, Indonesia and other countries, which together account for 65% of the world’s reserves. In particular, Guinea is world-famous for its high-grade, large-scale bauxite resources. It has been the main source of global bauxite growth in recent years and is currently the largest source of minerals for my country.
In October this year, Chinalco’s mining volume in Guinea hit a record high for a single month, and the amount of ore shipped back to China hit the best level in the same period in history; Tianshan Aluminum recently stated that the company’s bauxite project in Guinea has entered the production and mining stage and will soon be shipped to China. , the cost of bauxite raw materials can be greatly reduced in the future.
Judging from the distribution of source countries of my country’s imported bauxite in recent years, my country’s dependence on Guinea has increased rapidly. In the first nine months of this year, 74.5% of the bauxite came from Guinea, and its dependence on Australia has decreased significantly.
Another core country is Indonesia. In June 2023, Indonesia issued a bauxite export ban policy, requiring local resources to be tied to local alumina production capacity, landing projects domestically, creating more jobs and national income. Therefore, China’s aluminum Many companies have set up factories directly in Indonesia to reap the cost benefits brought by the local low-priced bauxite.
Jinjiang Group has planned a 6 million ton alumina production capacity in Indonesia in five phases. The first phase of 1 million tonnes was put into construction in April this year. The 2 million tonnes alumina project of Tianshan Aluminum, the world’s second largest alumina producer, was listed as Indonesia’s national strategic project; Nanshan Aluminum is also promoting a 2 million ton alumina expansion project and a 250,000 ton electrolytic aluminum project; Shandong Innovation Group also plans to build a 2 million ton alumina project in Indonesia.
Under the impetus of Chinese enterprises, advanced smelting technology, complete industrial chain have stationed in Indonesia, formed the upstream bauxite, alumina and electrolytic aluminum production in Indonesia, the domestic focus on aviation panels, automotive panels, and other high barriers, high value-added products development pattern.
Made in China to help, rough estimates, Indonesia’s alumina production capacity this year may exceed 50 million tons, is expected to increase to 80 million tons in 2026, become a global alumina production power, more China’s midstream and downstream aluminum products strategic back.
Currently, the economic development of the world’s countries is extremely unbalanced, many southern countries have rich reserves of upstream resources, but lack of mining, smelting and processing technology and market capacity. China is the combination of manufacturing capacity, advanced technology and the resources of the southern countries, mutual benefit and win-win; on the other hand, by virtue of the crushing supply advantage, so that the developed countries have to purchase.
The global aluminum industry pattern is the best embodiment of this pattern.
4.Conclusion
China is the only country in the world that has all the industrial categories, complete, prosperous and powerful, is the distinctive label of China’s industrial manufacturing resonates globally.
Compared with the comprehensive, complete, people generally overlooked, it is the huge scale advantage, so that China’s industrial products – including such as electrolytic aluminum, such as primary industrial products, can be in the price relative to global competitors have enough advantage. In Europe and the United States erected trade barriers against China at the moment, the value of scale, is the Chinese products continue to expand in the global killer app.
Based on the huge scale of manufacturing, China can, on the one hand, work in solidarity with developing countries to purchase resources; on the other hand, it can manufacture high-level, cost-effective industrial products for global distribution. And in the energy side, and formed a photovoltaic, wind power and other clean energy industry chain advantages, leading the global industrial civilization forward, but also from the side to enhance the barriers to industrial production.
Even in the global energy low-carbon transformation of domestic, other countries have to buy China’s new energy products.
It is no exaggeration to say that in the context of increased global economic turmoil, no country dares not think about the consequences of China’s restrictions on the export of certain industrial products. Starting with various rare earth and aluminum products, the world will have a clearer understanding of this. […]Read more…
