Making the Tungsten Carbide Raw Material

Cemented Tungsten Carbide is an incredible material. It was originally developed for use as a cutting tool, in machine tools applications, where it still finds wide use today.

When a mixture of powdered tungsten metal and carbon powder are raised to a very high temperature by an arc of electricity, while the whole mass is held in a carbon crucible, there is a complete chemical combination of the two elements to form a big lump of tungsten carbide ( WC ). This lump is crushed several times and then milled to form a fine powder. The powder is screened down to uniform particle sizes.
