Brown Fused Alumina ISO/JIS/FEPA
1. Description:
♦ Brown Fused Alumina is a product manufactured by gradual melting reduction of calcined bauxite in an electric arc furnace at high temperature (approximately 2000 degrees Celsius). Its chemical composition consists mainly 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) 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.
2. Applications:
♦ Wet and dry blasting
♦ Grinding, lapping and polishing media
♦ Resin bonded grinding wheels and segments
♦ Resin bonded abrasive and coated abrasive products
♦ Wear-resistant and fire-proof products
♦ Friction products and abrasion resistance ground
♦ Producing mold of precision casting
3. Grit Size Available (P, F):
