① 6063 aluminum alloy material. The main alloy elements are magnesium and silicon, which have excellent processing performance, excellent weldability, extrudability and electroplating, good corrosion resistance and toughness, easy to polish and color film, and excellent anodizing effect. It is a typical extrusion alloy. 6063 aluminum alloy profiles are widely used in building profiles, irrigation pipes, pipes, bars, profiles for vehicles, stands, furniture, elevators, fences, etc. due to its good plasticity, moderate heat treatment strength, good welding performance, gorgeous color of the surface after anodizing treatment and many other advantages.
(2) 6063 is a low alloyed Al Mg Si high plasticity alloy. It has many valuable features:
1. Heat treatment strengthening, high impact toughness, insensitive to notch.
2. Excellent welding performance and corrosion resistance, no tendency of stress corrosion cracking. Al Mg Si alloy is the only one without stress corrosion cracking.
3. After processing, the surface is very smooth and easy to anodize and dye. Its disadvantage is that after quenching, if it is kept at room temperature for a period of time, it will bring adverse effect on the strength (parking effect) in aging.
