Semiconductor parts polishing powder brown aluminum oxide

Brown fused alumina for fine grit grinding wheels

Brown fused aluminum oxide is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2000°C. Our BFA is made into different shapes and grit sizes ranging from macro to micro grits and powders. It is a tough, hard material with high strength, excellent wear and corrosion resistance and good thermal conductivity.

Brown fused aluminum oxide are available in standard grit and powder sizes and they can also be made to individual specifications. Please see below for information about some of our fused aluminum oxide materials.

Application：

♦Brown fused Alumina Used for refractory materials, castable refractory bricks, etc.

♦Brown fused Alumina for sand blasting – BFA as abrasive,hardness is moderate, high bulk density, no free silica, large specific gravity, good toughness, is an ideal “environmental” type sand blasting material, widely used in aluminum profiles, copper profile glass, washed denim Precision molds and other fields

♦Brown Fused Alumina for grinding grade abrasive—applied to picture tube, optical glass, monocrystalline silicon. Lens. watch glass.crystal glass.jade. etc.,
