2A12 aluminum plate is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity in annealing, rigid quenching and hot state, good spot welding, and tends to form intergranular cracks when gas welding and argon arc welding are used; The machinability of the alloy after quenching and cold work hardening is good. It is widely used to make various high load parts and components (but excluding stamping parts and forgings), such as skeleton parts, skin, spacer frame, wing rib, wing beam, rivet and other working parts below 150 ℃.
