Reliable fused aluminum oxide powder supplier. Brown grit for heavy grinding, white for precision work. 40+ grit sizes (F12-W50), ISO 9001 certified. Request technical specs & bulk pricing.
How to choose
Stop losing money on inefficient grinding:
01
Rough grinding too slow?
Brown Alumina F24-F60
02
Scratches on precision parts?
White Alumina W20-W50
03
Wheels wearing out fast?
Custom bulk density 1.85g/cm³
Brown vs White - What Works Where
| Job | Pick This | Why It Matters |
| Steel weld grinding | Brown F30-F60 | 2.5% TiO₂ = higher toughness |
| Medical tool polishing | White W10-W28 | Na₂O<0.2% = no contamination |
| Brake pad molding | Custom blend | Bulk density 1.75g/cm³ |
Workshop Tip:
"Brown alumina with >0.03% magnetic junk ruins copper parts. Ours: <0.008%."
Scenario Case
| Case | Surgical Tool Polishing |
| Part | Scalpel (420 stainless) |
| Issue | Brown streaks after polishing |
| Fix |
- White alumina W40 slurry - 0.2MPa pressure, 1200rpm |
| Result | Ra 0.08μm • Passed FDA cleanliness |
Non-Negotiables:
1. Never use brown alumina on aluminum (Fe causes blackening)
2. Use white alumina within 6 months after opening
3. Free MSDS
Assure
We deliver three certainties:
-
Composition Certainty: Batch-specific smelting curves + laser particle reports prove 99.6% Al₂O₃
-
Result Certainty: Get material-specific Grinding Parameters Card (e.g. 304 SS: W40 at 0.15MPa)
-
Accountability: 48-hour on-site diagnosis if issues arise-Engineer Wang with spectrometer
When brown streaks persist after 3 parameter adjustments, when 'high-purity' powder scratches silicon wafers-the flaw isn't your process, but the abrasive source.
