Brown Fused Alumin, the common name, also known as carborundum, is bauxite, carbon materials, iron filings after three materials in the furnace to melt reduction in the system of artificial corundum brown.It is mainly used in refractories, grinding wheel. 1.ok sand blasting - abrasive hardness, high bulk density, no free silica, heavy, good toughness
