What's the purpose of tungsten powder

Tungsten powder is a kind of metallurgical material, is a widely applied in industry, so what's the purpose of tungsten powder? Here is introduced:

Tungsten powder in addition to have certain request for impurity content, oxygen content control within a certain range. Commonly used tungsten powder granularity for Karl fischer average particle size of 2 ~ 10 microns. Tungsten powder for polygon particle shape. In addition, the specific surface of tungsten powder, apparent density, such as rock density and changes within a certain range. Performance of tungsten material production tungsten powder and tungsten powder metallurgy products quality has a direct impact, especially the influence of the purity and granularity is more apparent. Tungsten powder is based on the purity and granularity and classification of different purposes.

Tungsten powder processing is the main raw material of powder metallurgy tungsten and tungsten products. Pure tungsten powder can be made into silk, rods, tubes, plates and other processing of material and shape of a certain products. Tungsten powder mixed with other metal powder, can be made into all kinds of tungsten alloy, such as tungsten molybdenum alloy, tungsten rhenium tungsten alloy, copper alloy and high density tungsten alloy, etc. Another important application for tungsten powder is made from tungsten carbide powder, and the preparation of cemented carbide tools, such as turning tool, milling cutter, drill bits and mould, etc.
