Tungsten carbide balls are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves, flowmeters. TC balls are also used for coining and pivots, detents and tips for gages and tracers. Decimal-inch size tungsten carbide balls are widely used for ballizing or hole sizing. TC balls are also used for gauging and checking.
