7075-T6 cold drawn seamless tube

The 7 series aluminum alloy belongs to Al-Zn-Mg-Cu series super-hard aluminum, which is an ultra-high-strength deformed aluminum alloy that has been widely used in the aircraft industry in the late 1940s and is still widely used in the aviation industry. Its characteristics are: good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150 ℃, and particularly good low temperature strength; poor welding performance; tendency to stress corrosion cracking; poor corrosion resistance needs With aluminum or other surface treatment. Two-stage aging can improve the alloy's resistance to stress corrosion cracking.
