TUNGSTEN ROD

Purity: W>99.95% (99.98% can also be achieved on demand)

Density: >18.3g/cm3

Surface: Sintering surface, forged surface, ground surface, polished surface

Tungsten rod features: High hardness, low mechanical abrasion with a smooth surface. Moreover, it is characterized by high-temperature resistance and high creep resistance.

Tungsten Rod Applications

- Manufacturing components used in electric light source electric vacuum.

- Used as heating elements and refractory parts in high-temperature furnaces.

- Used as electrodes in the field of the rare earth metal industry.

- Electrode in the field of device and machining technology or in the lighting industry.
