Aluminium Alloy 6063
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.
Applications
6063 is typically used in:
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.
Aluminium Alloy 6063A
Aluminium alloy 6063A is a variation of 6063 with greater strength but retains the same good surface finish qualities and affinity for anodising.
Applications
6063A is used in the same applications as 6063. It is also used in:
Road transport
Rail transport
Extreme sports equipment

Temper Types
The most common tempers for 6063 aluminium are:
- O - Soft
- T6 - Solution heat treated and artificially aged
Weldability
Alloy 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.
Weldability – Gas: Good
Weldability – Arc: Very Good
Weldability – Resistance: Good
Brazability: Very Good
Solderability: Good
Fabrication
Workability - Cold: Average (Acceptable)
Machinability: Good
