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 itself is practically inert and extremely strong. Any attack is usually on the binder. Since other material is less expensive, the selection of tungsten carbide solely for corrosion resistance is usually not justified. In highly corrosive conditions, carbides with a more resistant binder can be supplied.
Grade | Hardness (HRA) | Density (g/cm) | Strength ( N/mm²) | Application |
YG6X | ≥92.0 | 14.9 | ≥2200 | Suitable for grinding, best wear resistance. |
YG6 | ≥90.0 | 14.95 | ≥2800 | Suitable for grinding, bearing ball, valve seat ball, more widely adapted. |
YG8 | ≥89.0 | 14.75 | ≥3200 | Suitable for grinding, bearing ball, valve seat ball, good versatility. |
YN6 | ≥90.0 | 14.8 | ≥2150 | This brand is a non-magnetic alloy, generally used for bearing ball, valve seat ball, good corrosion resistance, wear resistance is better than YN9. |
YN9 | ≥88 | 14.8 | ≥2500 | This brand is a non-magnetic alloy, generally used for bearing ball, valve seat ball, good corrosion resistance, strength is better than YN6. |
