1. Tungsten carbide ball

It is mainly used for ball milling and finish machining.

Tungsten carbide balls are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves and flow meters. These balls are also used for coining and as pivots, detents and tips for gauges and tracers. Tungsten carbide itself is practically inert and extremely strong. Any attacks are usually on the binder. Since other materials are less expensive, the selection of tungsten carbide solely for corrosion resistance is usually not justified. In highly corrosive conditions, carbides with a more resistant binder can be supplied.
Usage : ball pen , bearing , high precision instruments, hardness test machine, head pressure, mine, decorations and other special precision industry.
