7A09 aluminum round bar rod

Jan 24, 2023

7A09 aluminum alloy rod is Al-Zn-Mg-Cu super hard aluminum, good plasticity after solution treatment, especially good heat treatment strengthening effect, high strength below 150 °C, and particularly good low temperature strength; poor welding performance ; has a tendency to stress corrosion cracking; need to be coated with aluminum or other protective treatment. Two-stage aging improves the ability of the alloy to resist stress corrosion cracking. The plasticity in the annealed and quenched state is slightly lower than the same state of 2A12. Slightly better than 7A04, the static fatigue of the sheet. Notch sensitive, stress corrosion performance is better than 7A04.
7A09 aluminum alloy is an ultra-high-strength deformed aluminum alloy that has been used in the aircraft industry since the late 1940s and is still widely used in the aviation industry.

The7A09 aluminum round rod bar of φ8-φ260mm can produce cold-rolled stretched bars with tolerances below 0.3μm.
The products supplied by are strictly produced according to various national standards such as GB/T3191-2010, GB/T6892-2006 and GB/T3190-2008 to ensure the excellent quality of the products. The product can be customized according to the special requirements of the customer.
