Q1: What are the main differences between 5000 and 6000 series aluminum plates?

A1: 5000 series plates (like 5052) are alloyed primarily with magnesium, offering excellent corrosion resistance, superior weldability, and moderate strength, making them ideal for marine or chemical environments. 6000 series plates (like 6061) are alloyed with silicon and magnesium, are heat-treatable, and offer much higher yield strength along with excellent CNC machining characteristics.

Q2: Can you ensure high flatness and minimal internal stress for precision machining blanks?

A2: Yes. For high-end tooling and indexing plate applications, we provide specialized stress-relieved plates (such as 6061-T651). These blanks undergo stretching and precision leveling processes after heat treatment to eliminate internal stresses, ensuring the material will not warp or twist during intensive CNC milling.

Q3: What cutting methods do you use to supply precise cut-to-size blanks?

A3: Depending on your exact thickness, tolerance, and edge finish requirements, we offer precise high-speed circular sawing, water-jet cutting (best for heat-sensitive specs), or CNC laser cutting to deliver near-net shapes ready for immediate factory fabrication.

Q4: How do you prevent surface scratching on thick aluminum plates during shipping?

A4: Maintaining surface quality is standard procedure. We can apply heavy-duty protective PE or PVC film on one or both sides of the plate upon request. For global B2B transit, plates are securely interleaved with wood elements, banded with strong steel straps, and anchored onto heavy-duty wooden pallets to prevent moving or friction marks.
