Tungsten Carbide Ball
Key Features & Benefits
1. Unmatched Hardness & Wear Resistance
-
Hardness: Second only to diamond, with a Rockwell hardness of HRA 90–92.
-
Wear Life: 50x longer lifespan than steel balls, drastically reducing replacement costs in high-friction applications.
-
Surface Finish: Mirror-polished (Ra ≤0.02μm) or customized coatings (TiN, DLC) for reduced friction and enhanced performance.
2. Extreme Environment Durability
-
Temperature Resistance: Operate reliably from -200°C to +1000°C without deformation.
-
Chemical Resistance: Withstand acids, alkalis, and corrosive media (pH 2–12).
3. Precision Engineering
-
Tight Tolerances: Diameter accuracy of ±0.001mm (ISO 3290 standard) for seamless integration into精密 assemblies.
-
Custom Sizes: Available from 0.5mm micro balls to 50mm large spheres, with options for grooves, flats, or threaded holes.
