Product Description
Product Overview
This 30 Mesh Brown Fused Alumina Grain is a premium abrasive material manufactured through high-temperature arc smelting at 2000°C+. With a melting point of 2250°C, it delivers exceptional performance for heavy-duty grinding, cutting, and sandblasting applications.
Material Composition & Manufacturing
Brown fused alumina is produced from high-quality bauxite, anthracite, and iron filings. The manufacturing process involves arc smelting at temperatures exceeding 2000°C, followed by crushing, plasticizing via self-grinding machines, magnetic iron removal, and precise sieving into various mesh sizes.
Key Characteristics
- High purity with dense, hard texture
- Spherical pellet formation for consistent performance
- Excellent fluidity and corrosion resistance
- Low linear expansion coefficient
- No explosion, chalking, or cracking during application
- Superior cost-effectiveness compared to traditional brown corundum
