Brown Fused Alumina
Introduction of Brown Fused Alumina:
Brown Fused Alumina is fused under the high temperature of above 2250°C with high quality abrasive bauxite as raw material. Its characteristics: high purity, good crystallization, strong fluidity, low coefficient of linear expansion, corrosion resistance. The product has the characteristics of no initiation, no pulverization and no cracking in the application process.
The applications:
For abrasive: grinding wheel, abrasive belt, sandpaper, gauze, cutting sheet, sandblasting process, grinding, wear-resistant floor, water knife cutting, coated abrasive tools, consolidated abrasive tools, etc.
For refractory: castable, refractory brick, ramming material, skateboard, water mouth, ladle, furnace lining material, precision casting, etc.
