Supply 5056 national standard aluminum row, wholesale 5056 aluminum row

The main element is magnesium, which can significantly increase the strength of aluminum without excessively reducing its plasticity. Aluminum-magnesium alloy has good corrosion resistance and weldability. It also contains a small amount of manganese and chromium. Adding manganese can improve the corrosion resistance of the alloy, especially the ability to resist stress corrosion cracking, and ensure that the alloy has higher stability. The effect of adding chromium is similar to that of manganese, which can improve the resistance to stress corrosion, increase the strength of the body metal and welds, and reduce the tendency of welding cracks.
