Product Description

Application: Polished 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 is the most excellent seal face material in the seal material world.
