Brown aluminium oxide is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and 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 broze,etc.It also can be used as refractory materials.

• Black fused alumina/aluminum oxide (BA) (lower aluminum oxide abrasice) is a new type abrasive material for polishing various metal
• It is featured with high hardness, strong tenacity, good self-sharpening, good cohesiveness, 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, metal works, optical glass, bamboo or articles
• It is also the new grinding material of producing colophony grinding wheels, slice and emery cloth
