In industrial grinding and milling, media selection critically impacts process efficiency and outcomes. WC Warriors Ultra-Dense Grinding Balls deliver high-performance solutions for demanding applications across metallurgy, ceramics, electronics, and pharmaceutical industries.
These precision-engineered grinding balls are manufactured from tungsten carbide (WC), renowned for exceptional hardness and wear resistance. The tungsten carbide-cobalt (Co) composition ensures reliable performance in abrasive slurry environments.
| Property | Tungsten Carbide (WC-6%Co) | Alumina (99%) | Zirconia (YTZP) | Steel (440C) |
|---|---|---|---|---|
| Density (g/cm³) | 14.6-15.0 | 3.9 | 6.0 | 7.8 |
| Hardness (HRA) | 90-92 | 80-85 | 88-90 | 60-65 |
| Fracture Toughness (MPa*m½) | 10-12 | 4-5 | 7-10 | 15-20 |
| Media Type | Relative Wear Rate | Lifespan (vs. Steel) | Cost Efficiency |
|---|---|---|---|
| Tungsten Carbide | 1× (Benchmark) | 20-50× longer | Best long-term |
| Zirconia | 1.5-2× | 10-15× longer | High upfront |
| Property | Tungsten Carbide | Performance Impact |
|---|---|---|
| Corrosion Resistance | Good (pH 4-12) | Cobalt-bound grades sensitive to acids; nickel-bound resists pH 1-14 |
| Oxidation Resistance | Stable to 500°C | Avoid >600°C (cobalt binder oxidizes) |
