2A12 aluminum alloy is a high-strength duralumin, which can be strengthened by heat treatment, with medium plasticity in annealing, rigid quenching and thermal state, good spot welding weldability, and tendency to form intergranular cracks when welded with gas welding and argon arc welding; The machinability of the alloy after quenching and cold work hardening is still good, but it is not good when annealed.
