What do you know about the Tungsten Powder?

Tungsten powder is powdery metallic tungsten and is also used to prepare tungsten processing materials, tungsten alloys, cemented alloys and other tungsten products.

Performance standard

Apart from certain requirements for the content of impurities, the oxygen content of tungsten powder should be controlled within a certain range. Generally, the particle size of tungsten powder is 2～10μm and the particle shape of tungsten powder is polygonal. Besides that，the specific surface, bulk density and rolling density of tungsten powder also vary within a certain range. The properties of tungsten powder have direct effects on the production of tungsten materials and the quality of tungsten powder metallurgical products, especially on the purity and particle size. Tungsten powder is classified according to its purity and particle size and different uses.

Industrial application

Tungsten powder is the main raw material for powder metallurgy tungsten products and tungsten alloys, and pure tungsten powder can be made into tungsten wire, tungsten rod, tungsten tube, tungsten plate and other processing materials and certain shape products. Another important application of tungsten powder is the manufacture of tungsten carbide powder for the preparation of tools such as turning tools, milling tools, drills and molds.

Size grading

The quality of tungsten powder directly determines the quality of WC and its alloy properties. The classification of tungsten powder can effectively change the properties of powder, solve the problem of coarse and fine powder pinch, and reduce the difference between the minimum particle size, maximum particle size and average particle size, so as to produce thicker and more uniform tungsten carbide powder. Due to the characteristics of tungsten, it is not easy to be broken. Moderate crushing is carried out before classification, and the agglomerated particles in the powder are separated, which can effectively separate the powder and improve the uniformity. The classification must be strictly and carefully adjusted to the system operating parameters, and the optimal operation process should be found according to the characteristics of the original powder.
