3003 aluminum coil is a non-heat-treated alloy, and its mechanical properties can be improved by conventional cold processing. It is an AL-Mn alloy, which is the most widely used rust-proof aluminum. The strength of this alloy is not high (slightly higher than that of industrial pure aluminum), and it can not be strengthened by heat treatment. Therefore, cold working method is adopted to improve its mechanical properties: it has high plasticity in annealed state, good plasticity in semi-cold hardening, low plasticity in cold hardening, good corrosion resistance, good weldability and poor machinability.
3003 aluminum coils are also widely applied to ships/vessels, vehicles, automobile and inserter welding assemblies, fireproof pressure vessels, refrigeration equipment, television tower, drilling equipment, transport and communication facilities, missile elements, plate armors and so on.
3003 aluminium coil has excellent elongation and tensile strength and processing performance is good, stamping, stretch forming high performance.
