Ultra-fine Tungsten Carbide Powder

Submicron or ultrafine tungsten carbide powder with grain size < 1µm.

High-hardness and high-strength ultrafine tungsten carbide powder for cemented carbide is manufactured by direct carburization reaction of tungsten oxide and carbon powder. In particular, the WCP Series (low-volume powder) having the reduced number of agglomerates and increased apparent density without changing the particle size has been developed. This powder helps reduce shrinkage during cemented carbide sintering and is most suitable as material for micro drills, end mills, etc. that require higher hardness and higher strength.

Applications of ultra-fine tungsten carbide powder:

* Used as material for semi finished POT and plunger;  

*Used as material for tungsten carbide rods, tungsten carbide bars and other tungsten carbide products.

Due to the properties of high hardness and high strength, the ultra-fine grain tungsten carbide becomes the main developing direction of tungsten carbide materials. with the wide application of advanced manufacturing technology, large-scale production line and all kinds of precision high-speed machining center, the demand for high-performance cutting tools is growing, which bring about the growth of demand for ultra-fine grain tungsten carbide rods, tungsten carbide bars and other tungsten carbide products. Powder Extrusion Molding(PEM)Technology is developed on the basis of the extruding process of metals and polymer materials.
