3003
3003 is an AL-Mn alloy, which is the most widely used anti-rust aluminum. The strength of this alloy is not high (slightly higher than industrial strength).
Industrial pure aluminum) cannot be strengthened by heat treatment, so cold working methods are used to improve its mechanical properties: in the annealed state it has a very high The plasticity is good in semi-cold work hardening, but low in cold work hardening. It has good corrosion resistance, good weldability, and can be cut.Poor cutting performance.
