Alloy	Alloy series	Main features
2A50	Al-Cu-Mn	Heat-treated reinforced alloy, Al-Cu-Mg alloy. It has good plasticity in thermal state and high strength and plasticity in T6 state. It is widely applied to various large, medium and small forgings, such as aircraft frame, joint, bracket, rocker arm and so on, which are used for forging medium aviation industry. The electric arc welding and gas welding alloy contact welding performance is poor, the performance is acceptable, excellent performance of friction stir welding.
