7A09 Aluminium Sheet

7A09 aluminium sheet is Al-Zn-Mg-Cu alloy, which is an ultra-high-strength deformed aluminium alloy that has been used in the aircraft industry in the late 1940s and is still widely used in the aviation industry. Through proper T6 aging treatment, the material can reach its peak strength and has good resistance to exfoliation and corrosion. The composition ratio of 7A09 is higher than that of 7A04 aluminium sheet. The static fatigue, notch sensitivity, and stress corrosion resistance of the sheet are better than 7A04. 7A09 aluminium sheet is used in the aerospace industry with high strength, good weight reduction, and improved aircraft safety.

Specifications of 7A09 Aluminium Sheet

Chemical Composition of 7A09 Aluminium Sheet

The Features of 7A09 Aluminum Sheet

1. The heat treatment strengthening effect is particularly good, with high strength below 150 ℃, and particularly good low-temperature strength.

2. High ratio strength, good fracture toughness and thermal conductivity.

3. The plasticity after solution treatment is good. The plasticity under annealing and just quenching temper is slightly lower than that of 2A12 aluminum sheet with the same temper and slightly better than 7A04.

4. Poor welding performance. Prone to stress corrosion cracking, unless under T6 temper.
