Product Description

2A14 is a high strength forged Al-Cu-Mg-Si alloy, which can be heat-strengthened. From the point of view of chemical composition and properties, it can belong to hard aluminium alloy and forged aluminium alloy. It differs from 2A50 forged aluminium alloy in that the copper content of the alloy is more than double that of 2A50 alloy. The strength of the alloy after solution treatment and artificial aging is higher than that of 2A50, but its corrosion resistance is general and worse than that of 2A50. There is a tendency of intergranular corrosion and stress corrosion under artificial aging. The plasticity of the alloy is moderate, and the plasticity is not as good as that of 2A50 under hot condition. It has extrusion effect, indicating that the longitudinal and transverse properties of the alloy are different. It has good weldability and is suitable for resistance spot welding and seam welding. Its machinability is good.

2A14 aluminium alloy is used to manufacture free forgings and die forgings under high loads, as well as large frames, bridges, large shells, truck components, etc. However, due to the difficulty of hot pressing, the application range of the alloy is limited.
