Brown fused alumina 95%
Brown fused alumina is fused and crystallized under high tremparature from amixture of bauxite and other raw materials. It is brown and features hight hardness and toughness.The abrasives tools made of it are suitable for gringing metals of high-tensile strength such as carbonsteel,general-purpose alloy steel,malleable cast iron and hard bronze, etc.It also can be used as refratory materals, chemical additives, precision fuonding and antisliding materials.
