Aluminium 6063 is a medium strength alloy commonly referred to as an architectural alloy. It is normally used in intricate extrusions. It has a good surface finish, high corrosion resistance, is suited to welding and can be easily anodised. Most commonly available as T6 temper, in the T4 condition it has good formability.
This material is used for architectural applications, shop fittings, irrigation tubing, balustrading, window frames, extrusions and doors
