Primary tungsten powder

Primary tungsten powder is grayish black or dark gray metal tungsten powder, and has the characteristics of high specific gravity, high temperature resistance, and high hardness. It is a raw material for preparing tungsten processing materials, tungsten alloys, tungsten-based alloys, tungsten carbides, and other tungsten products.

Applications
Primary tungsten powder is a raw material for the preparation of tungsten processing materials, tungsten alloys, tungsten-based alloys, tungsten carbides, and other tungsten products. Its application involves mechanical processing, mining, geological drilling, construction tools, light bulb lighting, military engineering and other fields.

In the preparation of primary tungsten powder, the plasma method is currently preferred. The plasma method can produce primary tungsten powder with good particle quality, cleanness, less pollution, small size and narrow size distribution.

Packaging and storage
Primary tungsten powder should be inert gas anti-static packaging, sealed and stored in a dry, cool environment. It should not be exposed to air for a long time, prevent moisture from agglomerating, affecting the dispersion performance and the use of effects.
