The Elite Thermal Alloys benefit from a unique combination of properties make it the ideal material choice for equipment requiring high strength and high conductivity.

The Elite Thermal Alloys have been designed by our renowned metallurgists to give an advantage to engineers working in extreme environments.

Specifying Elite Thermal Alloys will reduce reliance on toxic high cost materials such as beryllium copper.

Performance can be improved and service life extended by using these alloys, resulting in significant cost advantages in oilfield exploration and processing, moulding applications, fine measurement tooling and other applications where high wear resistance and conductivity are important.

The Elite Thermal Alloys present engineers with design flexibility.

Manufactured in three tempers of increasing strength, it is also possible to customise the alloys to specific applications.
