Tungsten carbide balls are commonly used in valve balls, bearing balls, measuring balls and wear-resistant industrial applications.
Tungsten carbide balls are manufactured from tungsten carbide-cobalt sintered materials and are widely used in applications requiring very high hardness and wear resistance.
Common tungsten carbide ball grades include YG6 (WC-6), YG8 (WC-8) and other WC-Co carbide grades with different cobalt content and mechanical performance.
Compared with standard steel balls, tungsten carbide balls provide significantly higher hardness, better wear resistance and superior dimensional stability, making them suitable for precision valve balls, bearing balls and severe wear applications.
Due to their very high hardness and relatively brittle structure, tungsten carbide balls should be protected from severe impact loading or improper handling during assembly and operation.
