Tungsten carbide (TC) balls are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves and flow meters. They are also used for coining and as pivots, detents and tips for gages and tracers. Decimal-inch sized tungsten carbide balls are widely used for ballizing (below) or measuring hole sizes (see Inspection Products data sheet.) They are also used for inspection tools, comparative checking and gaging.
