Fabrication Characteristics
| Alloy | Weldability (MIG / TIG) |
Formability / Bending | Machinability | Surface Finish & Anodising Response |
|---|---|---|---|---|
| 6061 | Very good; suitable for structural welds (use compatible filler such as 4043 / 5356). | Good in O/T4; in T6 condition bending radius should be larger to avoid cracking. | Good; can be precision machined, drilled and tapped; widely used for CNC profiles. | Good natural finish; takes clear and coloured anodising with uniform appearance. |
| 6063 | Excellent weldability for architectural and window/door systems. | Excellent extrudability and cold formability, ideal for complex hollow & thin-wall sections. | Fair to good; best with sharp tools and proper lubrication. | Excellent anodising; high quality decorative and architectural finishes (matte / bright). |
| 6082 | Good weldability; preferred for structural applications, some loss of strength in HAZ. | Moderate; stronger alloy so requires larger bend radii, better in softer tempers. | Good; suitable for machining heavy structural components and precision parts. | Good general anodising response with decent colour uniformity. |
| 6005 / 6005A | Good weldability for frames, ladders, platforms and transport structures. | Good; balances strength and formability; used commonly for structural extrusions. | Good; acceptable surface finish after machining. | Good anodising and powder-coating response for architectural use. |
| 6463 | Good weldability for light architectural and decorative profiles. | Good; suitable for intricate shapes and small decorative sections. | Fair; designed more for surface quality than aggressive machining. | Excellent for bright anodised and mirror-like decorative finishes. |
Processing at Navkar Metal Syndicate: Aluminium sections can be supplied in mill finish, anodised, powder coated or mechanically polished, with cut-to-length, drilling, punching and fabrication options available on request for project-specific requirements.
