Product Description

7A04 7A09 aluminum coil strip

7A09 aluminum alloy is a high-strength alloy. The plasticity in the annealed and as-quenched state is slightly lower than 2Y12 in the same state and slightly better than 7A04. The plasticity of 7A09 aluminum alloy after quenching and artificial aging is significantly reduced. The static fatigue, notch sensitivity, and stress corrosion performance of 7A09 aluminum alloy sheet is slightly better than that of 7A04.

7A04 7A09 aluminum coil strip belongs to the Al-Zn-Mg-Cu series of super-duralumin. This alloy has been used in aircraft manufacturing since the 1940s. The ultra-high-strength deformed aluminum alloy is still widely used in the aviation industry.
