텅스텐 카바이드 볼 For Flowmeters
텅스텐 카바이드 볼 are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves, flowmeters. 텅스텐 카바이드 볼 are also used for coining and pivots, detents and tips for gages and tracers. Decimal-inch size 텅스텐 카바이드 볼 are widely used for ballizing or hole sizing. 텅스텐 카바이드 볼 are also used for gauging and checking.
속성
Tungsten carbide itself is practically inert; any attack is usually on the binder. Since other materials are less expensive, the selection of tungsten carbide for corrosion resistance is usually not justified. In severely corrosive conditions, carbides with more resistant binders can be supplied for specific applications.
