2A12 aluminum alloy is a kind of high-strength hard aluminum, which can be strengthened by heat treatment; 2A12 aluminum alloy has good spot weldability, and there is a tendency to form intergranular cracks when gas welding and argon arc welding. 2A12 aluminum alloy has good machinability after cold work hardening. Corrosion resistance is not high, often using anodic oxidation treatment and painting methods or adding aluminum coating on the surface to improve corrosion resistance.
