3003 O Aluminum Coil


3003 O aluminum coil is AL-Mn alloy, which is widely used as a kind of rust-proof aluminum. It cannot be strengthened by heat treatment, so cold working method is adopted to improve its mechanical properties. In the annealing state has a high plasticity, in the semi-cold hardening plasticity is good, cold hardening plasticity is low, good corrosion resistance, good weldability, bad machinability.Can be applied to wine bottle caps, beverage bottle caps, cosmetic caps, etc.
