30/60/80 Mesh Brown Fused Alumina Corundum Abrasive with 95% Al2O3 Content for Industrial Grinding and Polishing
Brown fused alumina is manufactured from high-quality bauxite, anthracite, and iron filings through arc smelting at temperatures exceeding 2000°C. The material undergoes crushing, plasticizing via self-grinding machines, magnetic separation for iron removal, and precise sieving into various mesh sizes. This industrial abrasive features dense, hard texture and spherical pellets ideal for multiple applications.
- High purity with excellent crystalline structure
- Superior fluidity and low linear expansion coefficient
- Exceptional corrosion resistance and durability
- No explosion, chalking, or cracking during application
- Cost-effective performance exceeding traditional brown corundum
