2A12 T351 aluminum plate sheet is a typical Al-Cu-Mg hard aluminum alloy with reasonable composition and good overall performance. It is the hardest aluminum alloy used in the largest amount. Better heat resistance, higher strength than 7075 aluminum alloy. The T-state and O-state have good forming properties and the heat treatment effect is outstanding. It is easy to produce cracks during welding and can be welded by special techniques.
