3A21 aluminum alloy is an Al-Mn alloy. 3A21 aluminum alloy is the most widely used anti-rust aluminum. Its strength is not high (only slightly higher than industrial pure aluminum) 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 in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability, and poor machinability.

Rust-proof aluminum, good corrosion resistance, good weldability
3A21 aluminum alloy is an Al-Mn series alloy. 3A21 aluminum alloy is the most widely used anti-rust aluminum. Its strength is not high (only slightly higher than industrial pure aluminum) 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 in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability, and poor machinability.
