7A09 Aluminum Bar is a high strength alloy from the 7000 series aluminium family, known for its excellent mechanical properties and suitability for demanding structural applications. After appropriate heat treatment (especially T6 and T651 tempers), this alloy exhibits superior tensile strength, high yield strength, good low temperature performance, and enhanced fatigue resistance, making it ideal for aerospace and other high performance fields.

This aluminum bar can be produced in various shapes (round, square, flat, and rectangular) and custom dimensions to meet specific fabrication and engineering needs. The material demonstrates good plasticity after solution treatment, although welding performance is limited and stress corrosion resistance may require protective coating or two stage aging.
Typical applications include aerospace structural components, aircraft frames, landing gear parts, industrial mechanical parts, automotive components, tooling, and high strength fabrication projects.
