Specialist temper designations

In industries where performance, strength and consistency are critical, choosing the right aluminium temper can make all the difference.

In this post we highlight 3 of the specialist Temper designations.

T832

To achieve T832 the tube is solution heat treated, cold worked, then artificially aged. Cold working provided by drawing improves strength and precision. Artificial ageing achieves the final mechanical properties. This sequence gives T832 its distinctive combination of strength, fatigue resistance and stability – ideal for applications where both performance and precision matter.

T9

To achieve temper T9 in aluminium alloys, the material must be solution heat-treated, artificially aged, and then cold-worked. This process enhances the strength and stability of the alloy.

T651

To achieve the T651 temper for aluminium, the material must undergo solution heat treatment followed by artificial ageing, and then it is stretched to relieve residual stresses. This process typically involves heating the aluminium to a specific temperature, quenching it, and then ageing it at a lower temperature for a set period.

The above tempers can only be achieved with capable heat treatment equipment and cold working capability both of which are available at Spartal.

Why Spartal?

At Spartal, we combine decades of experience in precision aluminium tube manufacturing with advanced process control and rigorous quality assurance.

Our expertise in cold drawing and heat treatment enables us to offer aluminium tube in all the above tempers – a capability unrivalled in the UK.

 This ensures our customers benefit from:

  • Consistent quality and repeatable results across production runs
  • Tailored dimensions and tolerances to suit individual project needs
  • Reliable delivery for time-critical programmes

For customers working in high-performance and safety-critical environments, that reliability isn’t just valuable – it’s essential.

If you require aluminium tube with exceptional strength, dimensional precision and performance consistency, Spartal provides a proven edge.

Spartal Finish

Does your section require a surface finish?
The two most common options are anodising and powder coating. You can find more details on these treatments within our Surface Treatments section.

If you’d prefer your section supplied in mill finish, please let us know if you plan to surface treat it later. This helps us ensure we recommend the most suitable product.
