Pink Aluminum Oxide — 80 Grit Precision Grade
Premium pink (ruby) fused aluminum oxide combining the toughness of brown alumina with the purity of white. The chromium oxide addition (2–3%) creates a media that is harder, tougher, and longer-lasting than standard white alumina while maintaining low contamination properties. The gold standard for precision grinding and critical surface preparation in aerospace and defense.
Key Features
- Chrome-doped for superior toughness and hardness
- Longer life than white alumina (30–40% more cycles)
- Low contamination — suitable for critical alloys
- Excellent edge retention for consistent cutting
- Premium aerospace and defense grade
- Consistent particle shape and size distribution
- ANSI B74.12 graded with lot traceability
