3A21 aluminum alloy belongs to both hard aluminum alloy and forged aluminum alloy from the composition point of view. Compared with 23A21, it has higher strength and better thermal strength due to its higher copper content. However, its plasticity in hot state is not as good as 3A21. 3A21 aluminum alloy has good machinability, good contact welding, spot welding and roll welding performance, poor arc welding and gas welding performance; it can be strengthened by heat treatment and has extrusion effect; it has low corrosion resistance and tends to be corroded during artificial aging.
