5052 aluminum coil also called AL - Mg alloy aluminum, magnesium is the main alloy elements in 5052 aluminum alloy, is one of the most widely used antirust aluminum, the alloy pocess high strength, especially the fatigue strength, plasticity and high corrosion resistance, cannot heat treatment to strengthen, in a cold work hardening plasticity is good, when the cold work hardening plasticity is low, good corrosion resistance, good weld ability, cutting performance is bad, can be polished.
