Aluminium alloy 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 readily suited to welding and can be easily anodised. Most commonly available as T6 temper, in the T4 condition it has good formability. Aluminium alloy 6063A is a variation of 6063 with greater strength but retains the same good surface finish qualities and affinity for anodising. Applications

- 6063 Architectural, applications, Extrusions, Window frames, Doors, Shop fittings, Irrigation tubing, 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. - 6063A 6063A is used in the same applications as 6063. It is also used in: Road transport Rail transport Extreme sports equipment
Stress corrosion cracking: no damage during operation and laboratory tests, general: very good, without protection in industrial or seawater atmosphere
6063 is suitable for all conventional welding methods. Welding wire generally should be alloy 5183 or alloy 4043. When maximum electrical conductivity is required use alloy 4043. For strength and conductivity use alloy 5346 and increase the size of the weld to compensate for the lower conductivity. Gas: Excellent; Arc:Excellent; Resistance:Excellent.
