1. Prodsuct Introdsuction
2A50 Aluminum forgings forged prodsuct parts
2A50 is a high strength forged Al-Cu-Mg-Si alloy, which can be strengthened by heat treatment. In a hot state, it has high plasticity and is easy to forge and stamp. After solution treatment and artificial aging, it has high strength and good process plasticity, but it has an extrusion effect, and its longitudinal and transverse properties are different. The corrosion resistance of the alloy is good, but there is a tendency of intergranular corrosion. The resistance spot welding and seam welding have good weldability, while the arc welding and gas welding have poor performance. Its cutting performance is good.

3.Prodsuct Features
Because of its good casting properties, 2A50 aluminum alloy is suitable for prodsucing large cross-section ingots. It is used as the blank of large hot-forged parts, such as partition frame, bracket, and rocker arm of aircraft. It is also used to manufacture medium and small forgings and die forgings with complex shape and medium strength.
The time interval between solution quenching and aging strengthening of 2A50 aluminum alloy should be less than 6 h, the overburning temperature should be 545 ℃, and the forging temperature should be 470-370 ℃.
