The Introduction of 2A12 Aluminum Sheet Plate

2A12 Aluminum sheet plate is a high-strength hard aluminum alloy in the aluminum-copper-magnesium system, which can be strengthened by heat treatment. Its composition is reasonable and its comprehensive performance is good. The spot welding of 2A12 aluminum plate has good weldability, and there is a tendency to form intergranular cracks when gas welding and argon arc welding are used. The machinability of 2A12 aluminum plate is still good after cold work hardening. The corrosion resistance of 2A12 aluminum plate is not high, and anodic oxidation treatment and painting method or aluminum coating are often used on the surface to improve the corrosion resistance.Click to Order
