Tungsten Metal (W) & Tungsten Powder 99.9% purity
Tungsten Rod is pressed and sintered from our high purity tungsten powders. Our pure tugnsten rod has 99.96% tungsten purity and 19.3g/cm3 typical density. We offer tungsten rods with diameters ranging from 1.0mm to 6.4mm or more. Hot isostatic pressing ensures our tungsten rods obtain a high density and fine grain size.
Tungsten Powder is mainly produced by the hydrogen reduction of high-purity tungsten oxides. UrbanMines is capable of supplying tungsten powder with many different grain sizes. Tungsten powder has often been pressed into bars, sintered and forged into thin rods and used to create bulb filaments. Tungsten powder is also used in electrical contacts, airbag deployment systems and as the primary material used to produce tungsten wire. The powder is also used in other automotive and aerospace applications.
