National standard spot quality grade 2a12CZ aluminum plate parameter guidance

& National standard spot quality grade C aluminum plate parameter guidance

Aluminum alloy characteristics and usage standards: replace the old B, characteristics and scope of application: Aluminum alloy is a kind of high-strength hard aluminum and cannot be strengthened by heat treatment. Aluminum alloy spot welding has good weldability, but there is a tendency to form intergranular cracks when using gas welding and argon arc welding. The machinability of aluminum alloy after cold work hardening is still good. The corrosion resistance is not high, and anodizing and painting methods are often used, or an aluminum layer is added to the surface to improve corrosion resistance. Purpose: It is mainly used to make various high-load parts and components (but not including stampings and forgings) such as aircraft skeleton parts, skins, partitions, ribs, spars, rivets and other working parts below ℃.
