As an Al Mn alloy, 3A21 is the most widely used antirust aluminum with low strength (only slightly higher than industrial pure aluminum) and cannot be heat treated and strengthened. Therefore, cold processing is often used to improve its mechanical properties; It has high plasticity in annealing state, and is good in semi cold hardening, low plasticity, good corrosion resistance, good weldability and poor cutting performance.
