4.03 micron Tungsten Powder Dark grey for making Tungsten Heavy Metal Alloys
Description:
Tungsten powder is dark grey powder, which is mainly divided into 3 types: coarse, medium, fine tungsten powder. And the size range we can produce is between 0.4 and 20 microns.
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.
The standard to judge tungsten powder quality on one hand lies in chemical composition control. On the other hand which is also significant, oxygen content must be limited within its relative range according to different F.S.S.S. Taking all above parameter in control not only ensure the quality of tungsten powder, but its derivative products.
Due to properties of high density, tungsten powder is perfect raw material to be made into tungsten heavy metal alloys. These alloys are used as mass balancing weights and attenuators in aircraft construction, in motors and power trains, as oscillating weights and centrifugal weights in machines and in equipment construction, and in medical technology for both protection from and focusing of ionizing radiation in xray and measuring devices.
