Tungsten Carbide Balls of various sizes
Core Advantages
✅ Unmatched Hardness: Hardness of HRA 90-92, second only to diamond, with wear resistance over 50 times that of steel balls.
✅ Durability in Extreme Environments: Resistant to high temperatures (1000°C), strong acids, alkalis, and high-pressure conditions.
✅ Precision Tolerance Control: Diameter tolerance of ±0.001mm (ISO 3290 standard), ensuring high-precision motion.
✅ Lightweight Design: Density of 14.8-15.1g/cm³, lighter than steel balls, reducing inertial losses.
✅ Wide Size Range: Custom non-standard sizes and surface treatments (polishing, sandblasting, coatings) available.
