High Hardness Brown Aluminum Oxide Blast Media P12 - P220 Grit Size For Sand Belts
High Hardness Brown Aluminum Oxide Artifical Corundum P60,P70,P90,P100 for Sand Blets
1. Product Description of Brown Aluminum Oxide Artifical Corundum
Brown Aluminum Oxide belongs to the group of artifical corundum,its contains at least 95% alumina, and
few Fe2O3,SiO2,TiO2 etc. Brown Aluminum Oxide is more durable than the one of white fused alumina.
It has the characteristics of high hardness,high toughness,widely used in varous industry to making bonded
abrasives,coated abrasives as well as blasting materials for various surface cleaning etc.
2. Types of Brown Aluminum Oxide Artifical Corundum
Brown aluminum oxide F grit for bonded abrasives and P grit for coated abrasives according to different usage;
Top Grade (Min95% Al2O3),off grade(Min90% Al2O3),second grade(Min80% Al2O3) according to different
alumina content.
Fixed Furnace and Tilting Furnace according to different furnace types.
Ball milling, crusher, barmac brown aluminum oxide according to different curshing methods.
