1. 소개 3A21 자료

      3A21 is an Al-Mn-based alloy, which is an excellent rust military aluminum alloy material. 3A21 aluminum plate is a widely used anti-rust aluminum with low strength (only slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, cold processing methods are often used to improve its mechanical properties. It has high plasticity in annealed state, and it is still good when hardened semi-cooled work, low plasticity during hardening, good corrosion resistance, good welding, and poor cutting performance.
