3A21 Aluminum Alloy Coil
3A21 aluminum coil is Al-Mn alloy.3A21 aluminum coil is a widely used anti-rust aluminum. Its strength is not high and it can not be heat treatment strengthening, so cold processing method is often used to improve its mechanical properties.  It has high plasticity in annealing state, good plasticity in semi-cold hardening, low plasticity in cold hardening, good corrosion resistance, good weldability, poor machinability.
