3A21 aluminum plate is an Al-Mn series alloy. 3A21 aluminum plate is a widely used anti-rust aluminum. Its strength is not high and cannot be strengthened by heat treatment. Therefore, cold working methods are often used to improve its mechanical properties. It has good plasticity when cold work hardening, low plasticity when cold work hardening, good corrosion resistance, good weldability and poor machinability.
