W6 pure Tungsten Powder with 0.4 - 20 microns Grain Size, Oxygen Content < 0.25%

Description:

Our tungsten powder is fabricated through reduction reaction of ammonium paratungstate with hydrogen under a heating up circumstance. The purity of product depends on reduction process which can be affected by temperature, loading quantity, moving rate of containers, gas speed and etc. Tungsten particle size increases with the rising temperature. And we can produce grain size of tungsten powder is between 0.4 and 20 microns.

Tungsten powder is the main ingredient to be processed into tungsten products and tungsten alloys. Among it, the most important application of the tungsten powder is made into tungsten carbide powder, then it can be manufactured into carbide tools, such as solid carbide end mills, drill bits, reamer, turning and so on.
