7075 aluminum is a cold treatment forging alloy, high strength, and far better than mild steel.

7075 aluminum tube is one of the most powerful alloy in business. Common corrosion resistance,good mechanical capacity and anodic reaction. Fine grain can make the deep drilling performance even better, tool abrasion resistance increase, and thread rolling is more different.

7075 aluminum tube processing features

7075 aluminum is called a super-high strength aluminum alloy, the yield strength of alloy is close to tensile strength. Yield strength and intensity is relatively high .But low plasticity and high-temperature strength,it should be used for bearing structure at room temperature and below 120.The alloy is easy to be processed, having better corrosion resistance and higher toughness. It is widely used in aviation and aerospace field, and become one of the most important structural materials in this field.
