Brown corundum is made of bauxite and anthracite as the main raw materials, and is smelted at high temperature in an electric arc furnace above 2000 degrees. Abrasive tools made of it are suitable for grinding materials with high tensile strength (steel, malleable cast iron, bronze, etc.) The metal is suitable for manufacturing ceramics, resin high-consolidation abrasive tools, grinding, polishing, sandblasting, precision casting, etc. It can also be used to manufacture advanced refractory materials. Brown corundum has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient, corrosion resistance, high temperature resistance, high strength and other characteristics.
Usage examples:1. Sand blasting and grinding of metal and non-metal products
2. Surface treatment, rust removal and oxide layer removal
3. Abrasives, resin and ceramic grinding wheels, cutting discs, grinding wheel belts
4. Rough grinding and high pressure cutting
5. Architectural ceramics, special ceramics, craft ceramics
6. Wear-resistant products and additives
7. Golf equipment, mechanical parts, glass sandblasting
8. Polishing
9. Polishing wax and polishing paste raw materials
