Carbide Ball And Valves

Carbide Ball And Valves

Tungsten Carbide Ball


Tungsten carbide balls are used where extreme hardness and wear resistance is required, in such application as bearing, ball pens, ball screws, valves and flow meters, coining and pivots, detents and tips for gages and tracers, decimal-inch, high precision instruments, hardness test machine, head pressure, mine, decorations and other special precision industry. Tungsten Carbide ball is also used as bullets in military.


Tungsten carbide itself is practically inert and extremely strong. Any attacks are usually on the binder. Since other material are less expensive, the selection of tungsten carbide solely for corrosion resistance is usually not justified. In high corrosive conditions, carbides with a more resistant binder can be supplied for specific applications.
