3A21 aluminum plate is al Mn alloy. 3A21 aluminum plate is a widely used antirust aluminum with low strength and can not be strengthened by heat treatment. Therefore, cold working method is often used to improve its mechanical properties; It has high plasticity in annealing state, good plasticity in semi cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability and poor machinability.
3004 aluminum sheet also belongs to a series of Al Mn alloy. Its strength is higher than that of 3003 aluminum sheet, and its formability, solubility and corrosion resistance are good. Parts with higher strength than 3003 alloy are required.
3003 aluminum plate is a typical al Mn alloy, which has good formability, very good corrosion resistance and weldability. It is often used to make power battery shell, cooker, food storage device, tank and bin on transportation equipment, sheet metal pressure vessel and pipeline in lightweight vehicles.
