Brown Abrasive is fused in an electrical furnace by high temperature.its main raw materials
are bauxite.anthracite.it dispaly brown.its chemical composition contains Al2O3,a small amount of
SiO2.TiO2.and Fe2O3.etc.the microhardness is 1800-2200kg/mm2.
the toughness is higher than silicon carbide.abrasive articles made of it are suited for grinding
metals of highten sile strength such as steel.annealed malleableiron and hard high-class
refractory products.the degree of refractory is up to 1850 centgrade.
