A better understanding of 3003 aluminum coil

3003 aluminum coil is a metal product that is subjected to flying shear after being rolled and drawn by a casting and rolling machine. Widely used in electronics, packaging, construction, machinery and other industries.

3003 is an AL-Mn alloy, which is the most widely used anti-rust aluminum, so the chemical properties of 3003 alloy aluminum coil are excellent. In terms of corrosion resistance, 3003 alloy aluminum coil is very good, which can be close to that of industrial pure aluminum. Corrosion resistance, good corrosion resistance to atmosphere, fresh water, sea water, food, organic acid, gasoline, neutral inorganic salt solution, etc., and good corrosion resistance in dilute acid.

3003 aluminum coil cannot be strengthened by heat treatment, so the cold working method is used to improve its mechanical properties: it has high plasticity in the annealed state, good plasticity in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, and good weldability , Poor machinability.
