3A21 Aluminum Plate

Product description：3A21 aluminum plate is an Al- Mn alloy, it is a widely used anti-rust aluminum, the strength is not high, and it can’t be heat-treated and strengthened, so cold processing method is commonly used to improve its mechanical properties; it has high plasticity in the annealed state and low plasticity, good corrosion resistance, good weldability and poor machinability in cold work hardening.
