Description:
Made from high quality bauxite, brown fused alumina is fusing and purifying in a pouring electric arc furnace at a temperature over 2200degree centigrade, and made into different grain sizes through many strict processes, because of which it becomes hard, tough, sharp and purity.
Application:
1. Brown fused alumina for coated and bonded abrasive tools
2. Brown aluminum oxide for lapping and polishing processes
3. Brown fused alumina for sandblasting
4. Brown aluminum oxide for producing mold of precision casting
5. Brow fused alumina as refractory materials
