Introduction to aluminum square tube

It is an Al-Mg-Si alloy with medium strength, good plasticity and excellent corrosion resistance. In particular, it has a tendency to be free from stress corrosion cracking, has excellent weldability, good corrosion resistance and cold workability, and is a promising alloy with a wide range of applications. It can be anodized and colored, or it can be painted on the enamel, suitable for building decoration materials. It contains a small amount of Cu, so the strength is higher than 6063, but the quenching sensitivity is also higher than 6063. After quenching, wind quenching cannot be achieved, and re-solution treatment and quenching aging are required to obtain higher strength.
