Brown Fused Alumina By Kind Security Co.,ltd.

Our offered Brown Fused Alumina is a product manufactured by gradual melting reduction of calcined bauxite in an electric arc furnace at high temperature. Its chemical composition mainly consists of Al2O3 (94.5-97%) and vestigial amounts of TiO2, SiO2, Fe2O3, CaO and MGO.
Brown Fused Alumina is characterized by good toughness, high mechanical resistance and hardness (9 in Mohs scale). The micro hardness of the material reaches about 1900kG/mm2.
Specific gravity (density)/ Grain density equals 3.90+/-0.05cm3. Bulk density depending on size equals 1.52-1.87g/cm3. It has relatively high thermal conductivity and low thermal expansion.
It is hard and tough material, which is the perfect material specifically manufactured to be used for general abrasive applications in bonded and coated abrasive tools, and lapping and polishing processes.
Brown Fused Alumina is used as a raw material in the manufacture of high alumina refractory.

Characteristics:
1) Choosing selected bauxite as raw material
2) Fused in arc electric furnace completely
3) High temperature resistance
4) High hardness
5) High intension
6) Good corrosion resistance
7) Good self-sharpening
8) Good thermal stability
9) Good chemical stability
