| Property | 6063-T5 | 6063-T6 |
|---|---|---|
| Ultimate tensile strength (min) | 150 MPa | 205 MPa |
| Yield strength (min) | 110 MPa | 170 MPa |
| Elongation (min) | 8% | 8% |
| Cooling method | Air-cooled from extrusion | Air-cooled |
T5 and T6 are used for the same applications. T5 may be preferred where tighter tolerances are needed, as its slower quench rate reduces distortion. 6063-T4 (naturally aged, not artificially aged) is also available for applications requiring maximum formability before final ageing.
Need a different alloy? Karnataka Metal Company also extrudes structural and industrial profiles in 6061, 6082, 6005, and other 6000 series alloys at the same Dabaspet plant. These are produced as custom profiles to order, suitable for bus body frameworks, railway structures, bridges, and heavy-duty applications.

Combined capacity: 4,800 TPA. Select profiles are also sourced from trusted extrusion partners to ensure the widest range of ready stock.
Sections are extruded to IS 733 and BIS/ISI standards. Our processes are audited by TUV under ISO 9001:2015 and ISO 14001:2015. With the BIS Quality Control Order effective April 2025, every section carries a BIS Standard Mark.
Our in-house laboratory uses a German spectrometer to verify alloy composition at the billet-casting stage and Japanese measurement instruments for dimensional accuracy. Every batch is dimensionally tested before dispatch.
Buy sections and get them machined, finished, and assembled under one roof. Karnataka Metal Company offers aluminium machining (cutting, drilling, punching, tapping, assembly) and in-house shot blasting, with anodising and powder coating outsourced but fully managed, from the same Bangalore campus.
For large construction and infrastructure projects, dedicated extrusion runs ensure consistent supply on schedule. Sections can be extruded, finished, and dispatched as a single coordinated order from the Bangalore campus.
