Product introduction
Anti-rust aluminum, good corrosion resistance, good weldability
3A21 aluminum plate is Al-Mn alloy, 3A21 aluminum plate is the most widely used rust-proof aluminum, the strength is not high (only slightly higher than industrial pure aluminum), can not be heat-treated and strengthened, so cold processing method is often used to improve its mechanical properties; It has high plasticity in the annealed state, good plasticity in semi-cold hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability and poor machinability.
Typical use
3A21 aluminum plate stock is mainly used for high plasticity and good weldability, such as aerospace, military equipment, fixtures, automobiles, transportation, propellant tanks, welding of skins, end frames, brackets, etc. Parts, as well as conduits that work in corrosive media.
