About Alloy 2A12
Alloy 2A12 or 2A11 aluminium sheet is a 2 series Al-Cu alloy, which mainly contains the alloy component Cu, and belongs to the heat-treated alloy sheet. Therefore, the 2A12 aluminium alloy strengthened by heat treatment has high strength. Besides, 2A12 aluminium sheet has excellent machinability and good spot welding property, but when gas welding and argon arc welding, there is a tendency to form intergranular cracks. And the corrosion resistance is not high, need to carry out surface treatment or aluminium coating to improve its corrosion resistance. Now, 2A12 aluminium sheet is mainly used for making various parts and components with high load (but not including stamping parts and forgings). CHAL 2A12 aluminium processing technology is in the leading level in the industry.
We 30 years focus on the development and production of 2A12 aluminum plate, product processing technology far beyond the national standards, we produce 2A12 aluminum plate can be used for rivets, missile components, truck hub, screw components, and so on, with the original factory warranty, you can rest assured purchase!
Features:
Corrosion resistance is not high, often use anodic oxidation and coating method or the surface coated with aluminum layer to improve the corrosion resistance.
