The main alloy elements of 6063 are magnesium and silicon. It has excellent processability, excellent weldability, extrudability and electroplating, good corrosion resistance and toughness. It is easy to polish and color film, and has excellent anodizing effect. It is a typical extruded alloy. 6063 aluminum alloy profile is used to make picture frame, mirror frame, advertisement frame and other profiles because of its good plasticity, moderate heat treatment strength, good welding performance and gorgeous color after anodizing.
