3A21 O Aluminum Composition

3A21 Aluminum sheet is an Al-Mn series alloy. 3A21 aluminum sheet 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 high plasticity in the annealed state. The plasticity is good during semi-cold work hardening, and the plasticity is low during cold work hardening, with good corrosion resistance, good weldability and poor machinability.
