5052 aluminum sheet is AL-Mg alloy aluminum sheet, is the most widely used antirust aluminum. The strength of the alloy is high, especially the fatigue strength. It has high plasticity and corrosion resistance, heat treatment can not be strengthened, in the semi cold hardening of the plastic is still good. When cold hardening, it has low plasticity, good corrosion resistance and good weldability. Cutting performance is poor, and can be polished.
