7075 T6510 T6511 aluminum round tube introduction
7075 T6510 T6511 aluminum round tube is a kind of commonly used alloy with various varieties. It contains zinc and magnesium. The most common aluminum alloy is 7075 alloy with the best strength, but it can not be welded, and its corrosion resistance is quite poor. Many CNC cutting parts are made of 7075 alloy. Zinc is the main alloy element in this series, and a small amount of magnesium alloy can make materials Can be heat treated to achieve very high strength characteristics. This series of materials are generally added with a small amount of copper, chromium and other alloys, among which 7075 aluminum alloy is the best, with the highest strength, suitable for aircraft frame and high-strength accessories

Production process of
7075 T6510 T6511 aluminum round tube
Zinc is the main alloy element in 7075. Adding magnesium to the alloy containing 3% - 7.5% zinc can form mgzn2 with remarkable strengthening effect, which makes the heat treatment effect of the alloy much better than that of aluminum zinc binary alloy. With the increase of zinc and magnesium content in the alloy, the tensile strength will be further improved, but the resistance to stress corrosion and exfoliation corrosion will be reduced. After heat treatment, it can achieve very high strength characteristics.
