Tungsten Carbide Ball Bearing and Valve Balls for Oilfield and Chemical Industry

Product details

Premium Material- Ultra High Density Tungsten Carbide:Our tungsten carbide polished ball is manufactured from high-quality cemented carbide ball material, primarily composed of tungsten carbide (WC) with cobalt (Co) binder. Compared with traditional steel balls, tungsten carbide ball offers significantly higher hardness (HRA 90-94), exceptional wear resistance, and superior compressive strength. The high density structure ensures excellent stability under extreme working conditions such as high pressure, high temperature, and corrosive environments. This makes it an ideal choice for valve balls, tungsten ball bearing, and carbide ball valve applications.

Advanced Manufacturing Process-Precision Grinding & Polishing:Each tungsten carbide polished ball undergoes a strict manufacturing process including powder mixing, pressing, sintering, precision grinding, and mirror polishing. HIP sintering for enhanced density and structural integrity High-precision grinding ensures tight tolerance (G10-G100 level available) Mirror polishing process achieves ultra-smooth surface finish (Ra ≤ 0.02 μm) This advanced process guarantees perfect roundness and surface quality, which is critical for sealing performance in carbide ball valve and OEM valve ball seat tungsten carbide systems.

Excellent Wear & Corrosion Resistance:Compared to stainless steel or chrome steel balls, tungsten carbide ball performs exceptionally well in abrasive and corrosive environments. Outstanding resistance to abrasion and erosion Strong corrosion resistance against acids, alkalis, and chemical media Long service life even in oil & gas, mining, and chemical industries This makes it widely used as valve balls in high-demand applications such as slurry transport, drilling systems, and chemical processing pipelines.
