2017A aluminium alloy is a heat treatable and wrought aluminium product which includes the significant addition of copper as an added alloying element.It is a short-chipped alloy, which is suitable for treatment. The alloy has a low corrosion resistance, and it is not suitable for welding because of the high content of copper. It is not suitable for decorative anodising.The material offers an attractive combination of high strength with excellent fatigue resistance. 2017A offers good corrosion resistance though traditional welding is not possible as the corrosion resistance characteristics would be affected. Welding is possible using resistance welding techniques. With superior strength, ductility and formability, 2017A aluminium is commonly used in engineering applications.
This alloy is used, due to its high strength and good workability, in the aerospace industry and in defense and aviation technology.
Commercial applications for this engineering material include:
- Aerospace components
- Automotive components
- Fasteners
- Rivets
- High strength components
- Structural components
