Product Description
| 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 |
| Compressive Strength (GPa) | 4.5–6.0 | 2.5 | 2.0 | 2.0 |
| Elastic Modulus (GPa) | 550–650 | 380 | 200 | 200 |
Key Takeaways:
2× Harder than alumina, 3× harder than steel – Minimal wear in abrasive environments.
Highest density – Delivers superior kinetic energy for efficient grinding.
Exceptional compressive strength – Withstands high-load milling.
| 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 |
| Alumina | 3–5× | 5–8× longer | Moderate |
| Steel | 50–100× | Baseline | Low initial cost |
Real-World Example:
In cement ball mills, WC media lasts 2+ years vs. steel’s 1–2 months.
| 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). |
| Thermal Shock | Moderate | Avoid rapid quenching (>150°C/min). |
Best For:
Wet grinding of abrasive slurries (e.g., mining ores).
Organic solvents (no chemical reaction).
Particle Size Reduction: Achieves nanoscale fineness (D90 < 100nm) in high-energy mills.
Throughput: 30–50% faster than alumina/zirconia due to higher density.
Contamination Risk: Near-zero (critical for battery materials, electronics).
Optimal Applications:
Mining: Ore pulverization (gold, copper).
Ceramics: Nano-powder production.
Paints/Inks: Color-intensive grinding.
| Industry | Benefit of WC Grinding Media |
|---|---|
| Mining | 50× lifespan vs. steel in gold ore processing. |
| Aerospace | No Fe/Ni contamination in Ti alloy powders. |
| Electronics | Ultra-pure grinding for semiconductor materials. |
| Oil & Gas | Drilling mud additives with minimal wear. |
✅ Unmatched Hardness – Lowest wear rate in extreme abrasion.
✅ High Density – Faster grinding with less energy.
✅ Chemical Stability – Resists most solvents/slurries.
✅ Longest Lifespan – ROI justified in 6–12 months.
