3003 aluminum coil
3003 aluminum coil is AL-Mn series alloy, which is the most widely used anti-rust aluminum. It cannot be strengthened by heat treatment. Therefore, cold working method is used to improve its mechanical properties; it has high plasticity in the annealed state and is hardened in semi-cold work. When the plasticity is still good, the plasticity is low when cold work hardening, the corrosion resistance is good, the weldability is good, and the machinability is poor.
