China Alloy Steel Wear Parts Hard Carbide Balls, Find details about China Precision Carbide Ball, Carbide Ball Polished from Alloy Steel Wear Parts Hard Carbide Balls
Application: 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.
•One of main reasons for using Tungsten Carbide is the additional wear resistance that can be achieved in both moving and static parts.
•This is particular the case in serve service conditions, such as high temperature,and high levels of corrosion and abrasion.
