What materials are best for daily processing?
-
Al₂O₃ ≥ 85–95%, Cr₂O₃ approximately 2–15%. Chromium corundum is a chromium-containing corundum abrasive that combines high hardness with improved toughness, suitable for high-speed fine grinding, dressing, and surface finishing of both metals and non-metals.
- Rough Grinding/Deburring: Coarse grit (D50 200–500 µm) → Highly efficient burr removal.
- Semi-fine Grinding/Contour Finishing: Medium grit (D50 80–200 µm) → Balances grinding life and surface quality.
- Fine Grinding/Pre-Polishing: Fine grit (D50 10–80 µm) → Lower surface roughness.
- Ultra-fine/Mirror Polishing (Specific Formulations): Micronized powder (D50 <10 µm) → Used with binders or slurries.
-
All advantages are simple and verifiable.
"Longer Lifespan" - Standard tests show a lifespan increase of ≈20–35%.
"Less Powdering" - Breakage/powdering rate reduced by 41%.
"Stable Surface Quality" - Allows customers to process with peace of mind, purchase with confidence, and produce with confidence.

In the cutting field, chromium corundum is commonly used in cutting wheels, tool dressing, and grinding media. Its key characteristics are high hardness, good toughness, and stable batches, which improve cutting efficiency and reduce unnecessary damage to tools and workpieces.
- Roughing and rapid removal: Coarse grain (high D50) → High removal rate, tolerance to higher loads.
- Finishing/Semi-finishing: Medium grain (medium D50) → Balanced removal rate and surface quality.
- Tool dressing and high-precision cutting: Fine grain/micro powder (low D50) → Control of cutting forces and surface roughness.
- Place a table on the page titled "Application → Recommended D50 → Suggested Operating Conditions (Speed/Feed/Bond)".
