Abrasives
Brown aluminum oxide abrasive is fused and crystallized under high temperature from a mixture of bauxite and other materials. It is characterized by its high hardness, good toughness and sharp shape in particles. Suitable for grinding metals of high-tensile strength such as carbon stele, general purpose alloy steel, malleable cast-iron and hard bronze etc.

White fused aluminium oxide is made with an electric furnace from high-grade alumina powder as raw material. The resulting mineral has higher hardness and slightly lower toughness than brown fused alumimium oxide. Characterized by its high purity, strong grinding ability, abrasive tools made of it are suitable for grinding and polishing of cutting tools, precision-castings, spraying and coasting, medium body for chemical industry applications, special ceramics and high-grade refractory materials.
