YANNUO BROWN FUSED ALUMINA
  
Brown Fused Alumina P Grain for Coated Abrasives
Introduction:
Brown fused alumina is made by electric arc furnace smelting under high temperature with the raw material of bauxite, anthracite and scrap iron. The main ingredient is AL2O3. It is characteristic with high hardness, high toughness and high abrasion resistance. Brown fused alumina P grain is widely used in coated abrasive such as abrasive cloth, abrasive paper abrasive belts, etc.
