The main alloying elements in 6061 alloy are magnesium and silicon, which have medium strength, good corrosion resistance, weldability, and good oxidation effect. They are widely used in various industrial structural components that require certain strength and high corrosion resistance.
Aluminum 6061 has excellent characteristics such as processing performance, good corrosion resistance, high toughness, no deformation after processing, easy coloring film, and oxidation effect.
It belongs to the Al Mg Si alloy system, with medium strength, good plasticity, and excellent corrosion resistance. Especially without the tendency of stress corrosion cracking, it has excellent weldability, corrosion resistance, and cold workability, making it a widely used and promising alloy. It can be anodized and colored, or painted with enamel, suitable for use as a building decoration material. It contains a small amount of Cu, so its strength is higher than 6063, but its quenching sensitivity is also higher than 6063. After extrusion, it cannot achieve air quenching and requires re solution treatment and quenching aging to obtain higher strength.
