Key Takeaways:
99% Alumina offers 30% lower wear than 92% grade.
2–5x longer lifespan vs. steel in abrasive slurries.
Harder than zirconia but less tough (ideal for fine grinding).
| Property | Alumina (99%) | Performance Impact |
|---|---|---|
| Chemical Inertness | Resists pH 1–14 | Safe for acids/alkalis, pharmaceuticals. |
| Max Temperature | 1,600°C | Stable in kilns, calcination. |
| Thermal Shock | Moderate | Avoid rapid quenching (>200°C/min). |
| Contamination Risk | None | Zero metal ions (critical for Li-ion batteries). |
Vs. Competitors:
Beats steel in corrosion resistance.
Outperforms silica sand in wear & consistency.
Particle Size Reduction: Achieves sub-micron fineness (D50 < 1µm) in wet/dry mills.
Speed: Higher density (vs. silica) improves kinetic energy transfer.
Consistency: Uniform shape/size prevents clogging in bead mills.
Best For:
High-purity materials (e.g., ceramics, electronics powders).
Slurry processing (paints, dyes).
| Industry | Benefit of Alumina Balls |
|---|---|
| Mining | 50% lower replacement cost vs. steel in ore grinding. |
| Pharma | FDA-compliant, no endotoxin release. |
| Batteries | Prevents Fe/Ni contamination in cathode materials. |
| Paints | Maintains color purity (no metal leaching). |
| Media Type | Cost per kg | Lifespan (hours) | Cost per Ton Ground |
|---|---|---|---|
| Alumina (92%) | $5–10 | 2,000–3,000 | $0.50–1.00 |
| Steel | $2–4 | 500–800 | $2.00–4.00 |
| Zirconia | $50–100 | 5,000+ | $0.20–0.50 |
Trade-Off:
Alumina balances cost and performance – Ideal when zirconia is over-spec.
✅ Cost-Effective: 3x cheaper than zirconia for moderate abrasion.
✅ High-Purity: 99.9% Al₂O₃ for sensitive applications (e.g., pharma).
✅ Versatile: Works in ball/attritor/planetary mills.
✅ Low Maintenance: Non-corrosive, easy to clean.
Limitations:
Not for high-impact milling (e.g., hammer mills).
Thermal shock risk in rapid cooling applications.
We supply:
Sizes: 1mm–50mm (±0.01mm tolerance).
Grades: 92%, 95%, 99%, ZTA-composite.
Certifications: ISO 9001, RoHS, FDA (for pharma).

FAQ
What are alumina ceramic balls made of?
They are made from aluminium oxide (Al₂O₃), a high-purity ceramic material known for its hardness and wear resistance.
What are the key properties of alumina ceramic balls?
High hardness, excellent wear resistance, chemical stability, high-temperature resistance (up to 1600°C), and electrical insulation.
What are alumina ceramic balls used for?
They are used as grinding media, bearing components, valve balls, and in applications requiring wear resistance and chemical inertness.
Why choose alumina balls over steel or other ceramics?
They offer superior wear resistance, chemical stability, and are lighter than steel, making them ideal for specific applications.
What sizes are available for alumina ceramic balls?
Sizes typically range from 1mm to several inches, depending on the application.
