7075 aluminum rod bar stock performance and advantages

7075 which contains zinc and magnesium. The more common aluminum alloy is high in strength, but it can't be welded, and its corrosion resistance is quite poor. Many CNC cutting parts are made of 7075 alloy. Zinc is the main alloying element in this series, and a small amount of magnesium alloy allows the material to be heat treated to very high strength properties. This series of materials is generally added with a small amount of copper, chromium and other alloys, among which the number 7075 aluminum alloy is especially top grade, the highest strength, suitable for aircraft frames and high-strength accessories.
