What Is 7075 Aluminum Alloy?

Nov 24, 2022

7075 aluminum alloy is a cold treated forging alloy with high strength, much better than mild steel. 7075 is one of the most powerful commercial alloys. 7075 materials are generally added with a small amount of copper, chromium and other alloys. Among them, 7075-T651 aluminum alloy is particularly superior. It is known as the best product of aluminum alloy, with high strength and superior to any mild steel. The alloy has good mechanical properties and anodic reaction. Its representative uses include aerospace, mold processing, mechanical equipment, tooling and fixtures, especially for manufacturing aircraft structures and other high stress structures with high strength and corrosion resistance.
