7075 t7351 round bar

Feb 10, 2023

7075 t7351 round bar contains zinc and magnesium. The common aluminum alloy has high strength, but it can't be welded, and its corrosion resistance is quite poor. Many parts manufactured by CNC machining use 7075 t7351 round bar. Zinc is the main alloy element in this series. With a little magnesium alloy, the material can be heated to achieve very high strength. This series of materials are generally added with a small amount of copper, chromium and other alloys. Among them, 7075 t7351 round bar is the best one with high strength, which is suitable for aircraft frames and high-strength accessories
