0.4 - 20 μm Tungsten Powder 99.95% W for processing Tungsten Products
Description:
Tungsten, also known as wolfram, is a chemical element with symbol W and atomic number 74.
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.
Our tungsten powder are available 200 mesh, size ranging from 0.4 to 20 microns, high purity above 99.95%. In addition, we can meet your special requirements.
Tungsten\'s high melting point makes tungsten suitable for aerospace and high temperature uses such as electrical, heating, and welding applications.
