Aluminium, Commercial Alloy
6063A T6 Bar & Extrusion
High strength architectural aluminium alloy.
Aluminium alloy 6063A is a variation of 6063 but with greater strength.
It still retains the same good surface finish qualities and affinity for anodising as 6063.

- Good surface finish
- Readily suited to welding
- Easily anodised
- Good formability in the T4 condition
Additional Information
Weldability
- 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.
