AA 6063 is an aluminium alloy, with magnesium and silicon as the alloying elements. The standard controlling its composition is maintained by The Aluminum Association. It has generally good mechanical properties and is heat treatable and weldable. It is similar to the British aluminium alloy HE9.

6063 is the most common alloy used for aluminium extrusion. It allows complex shapes to be formed with very smooth surfaces fit for anodizing and so is popular for visible architectural applications such as window frames, door frames, roofs, and sign frames. Applications requiring higher strength typically use 6061 or 6082 instead.

It has a good surface finish, high corrosion resistance, is readily suited to welding and can be easily anodised. Most commonly available as T6 temper, in the T4 condition it has good formability.

In balustrading the rails and posts are normally in the T6 temper and formed elbows and bends are T4. T4 temper 6063 aluminium is also finding applications in hydroformed tube for chassis.

Architectural Applications: 6063 is commonly used in architectural applications such as window frames, door frames and roofing systems due to its corrosion resistance and excellent finish properties.
Automotive industry: 6063 aluminum alloy is used to produce auto parts due to its light weight, strength and corrosion resistance.Aluminium alloy 6063 is used in:Architectural applications、Extrusions、Window frames、Doors、Shop fittings、Irrigation tubing.
