3A21 Aluminum Sheet
3A21 aluminum sheet is an Al-Mn series alloy. it is the most 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. Good plasticity during semi-cold work hardening, low plasticity during cold working.
