5052 aluminum plate is Al-Mg alloy aluminum plate, magnesium is the main alloy element in 5052 alloy aluminum plate, is one of the most widely used antirust aluminum. This alloy has high strength, especially with fatigue strength: high plasticity and corrosion resistance, can not be heat treatment strengthening, in the semi-cold hardening plasticity is good, cold hardening plasticity is low, good corrosion resistance, good weldability, poor cutting performance, polishing。
