White fused aluminium oxide is electrically fused in the furnace with high grade alumina powder as raw materials. It has higher hardness and slightly lower toughness than brown fused aluminium oxide, characterized by its high purity, strong grinding ability, abrasive tools made of it are suitable or grinding high speed steel, high carton steel, etc. It also can be used as materials for grinding and polishing precision-casting, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials, etc.

Brown aluminium oxide is fused and crystallized under high temperature from a mixture of bauxite and other raw materials. It is characterized by its high hardness, good toughness and sharp shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as carbon steel, general-purpose alloy steel, annealed malleable iron and hard bronze, etc. It also can be used as refractory materials

Silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials.Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina.It is brittle and sharp and has electrical and hedat conductivity in some degree.The abrasives made of it are suitable ofr working on cast iron,non-ferrous metal,rock,leather,rubber,etc.It is also broadly used as refractory material and metallurgical additive.

Black Aluminium Oxide Abrasive(lower Aluminium Oxide Abrasive)is a new type abrasive material for polishing various metal works.It is electrical fused in an arc furnace from aluminium oxide as raw material.Black Aluminium Oxide Abrasive is featured with high hardness.strongtenacity,good self-sharpening,better cohesiseness,higher durability,less heat generated in grinding and giving the metal works high finish,less power weakened in grinding It is mostly used in grinding and polishing stainless steel,metalworks,optical glass,bamboo or articles.And itis also the new grinding material of producing colophony grinding wheels, slice,and emery cloth.
