7055 T77511 7075 T6 T651 flat round bar

7075 T6 T651 flat round bar is the most common aluminum alloy material with the best strength, but it cannot be welded, and its corrosion resistance is quite poor. Many CNC machining parts are made of 7075 alloy. Zinc In this series are the main alloying elements, plus a little magnesium alloy allows the material to be heat treated to very high strength properties. This series of materials generally add a small amount of copper, chromium and other alloys, and among them, the number 7075 aluminum alloy is particularly high-quality, with the highest strength, suitable for aircraft frames and high-strength accessories.
 


7055 T77511 T6 T651 flat round bar, 7055 aluminum alloy was successfully developed by Alcoa in 1991. It is the 7xxx series aluminum alloy with the highest degree of alloying. The main varieties are 7055-T7751 thick plate and 7055-T77511 flat round bar extrusion pieces.
 
Compared with 7150 aluminum alloy, 7055 T77511 T6 T651 flat round bar has improved tensile and compressive strength while maintaining some important properties such as fracture toughness and corrosion performance. The tensile and compressive strength of 7055-T77 is higher than that of 7150. -T77 is 10% higher and its corrosion performance is between 7150-T6 and 7150-T77.
