3A21 aluminum plate sheet belongs to Al-Mn aluminum alloy, is a kind of widely used anti rust aluminum, the intensity is not high (only slightly higher than that of pure aluminum), can be strengthened by heat treatment, so we often use cold processing methods to improve its mechanical properties; in the annealed state it has high plasticity, in the semi cold hardening plastic is good, when the low plasticity of cold hardening, good corrosion resistance, good weldability, poor machinability.

Performance advantage
1, 3A21 aluminum plate sheet is a typical antirust aluminum, with excellent corrosion resistance, can adapt to the humid environment;
2, good weldability, good tensile strength, elongation is 25% better than 3003 aluminum plate;
3, smooth surface, good plasticity, pressure resistance;
