  3 a21 aluminum plate for Al - Mn alloy, 3 a21 aluminum sheet is a kind of widely used antirust aluminium, strength is not high (only slightly higher than the industrial pure aluminum), can't heat treatment to strengthen, reason often use cold working methods to improve its mechanical properties; In the annealed state with high plasticity, in a cold work hardening plasticity is good, when the cold work hardening plasticity is low, good corrosion resistance, good weldability, cutting performance is bad.
