3A21 O Aluminum Coil

3a21 O aluminum Coil is Al-Mn alloy, 3A21 aluminum Coil is a widely used rust-proof aluminum, low strength, can not be strengthened by heat treatment, so cold working method is often used to improve its mechanical properties; In the annealing state has high plasticity, in the semi-cold hardening plasticity is good, cold hardening plasticity is low, good corrosion resistance, good weldability, bad machinability.
