Tungsten products

Concentrates

Scheelite and wolframite (hübnerite, ferberite) concentrates typically contain 65-75% WO3. more>>

Ammonium Paratungstate

APT is the most important precursor for the majority of tungsten products. more>>

Oxides and Acid

Tungsten trioxide (WO3) and TBO (WO3-X) are the most important precursors in the line from oxide to W and WC powder. Tungstic acid has a very high specific surface and gained again importance for production of ultrafine W and WC powder. more>>

Tungsten Metal Powder

Starting powder for all cemented carbide grades, ductile tungsten and many tungsten alloys. more>>

Tungsten Carbide Powder

The intermediate between W powder and the different cemented carbide grades. more>>

Ferrotungsten and Melting Base

Are master alloys used in manufacturing of tungsten containing steels. more>>

Chemicals

Diverse tungsten compounds find their use in manifold applications. more>>
