Tantalum Tungsten Alloy Products (Ta2.5W, Ta10W) Selection Notes

Tantalum Tungsten Alloy Products (Ta2.5W, Ta10W) belongs to the tantalum products range and is selected for corrosion resistance, biocompatibility and high-temperature stability. It is commonly used in shafts, pins, supports, electrodes, fixtures and machined components as well as chemical processing, medical devices, electronics, vacuum systems and high-temperature components. When requesting a quote, confirm diameter, length, straightness, tolerance, surface finish and quantity.

Ta-2.5W (R05252)

Ta-2.5W is a tantalum alloy containing nominally 2.5% tungsten. The tungsten addition increases strength compared with unalloyed tantalum while maintaining a useful combination of ductility, corrosion resistance, high-temperature stability, and fabrication capability.

Ta-2.5W is commonly selected when an application requires higher strength than pure tantalum without the higher tungsten content of Ta-10W.

Ta-10W (R05255)

Ta-10W contains nominally 10% tungsten and provides higher mechanical strength than pure tantalum and Ta-2.5W.

It is suitable for demanding high-temperature, structural, chemical-processing, vacuum, and specialized engineering applications where increased strength is an important material-selection factor.
