Learn what is 7075 aluminum alloy?

F19a8760

7075 aluminum alloy is a cold-treated forged alloy with high strength, far better than mild steel. 7075 is one of the most powerful alloys commercially available. 7075 material generally adds a small amount of copper, chromium and other alloys, the series of 7075-T651 aluminum alloy is particularly high-grade, known as the best aluminum alloy products, high strength, better than any mild steel. This alloy also has good mechanical properties and anodic reaction. Representative uses include aerospace, mold processing, mechanical equipment, tooling fixtures, especially for the manufacture of aircraft structures and other high-stress structures requiring high strength and strong corrosion resistance. So how to understand what is 7075 aluminum alloy? Let Nobo Smart Manufacture tell you
