Brown Fused Alumina, HS Code 28181010, CAS No. 1344-28-1, it 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+/-0,05 g/cm3. Bulk density depending on size equals 1,68-1,95 g/cm3. It has relatively high thermal conductivity and low thermal expansion. As regards electricity it is an insulator.

Brown Fused Alumina Application:
- Used to produce high grade refractory, castable, refractory brick; Main size is 1-3, 3-5, 5-8mm.
- Sandblasting—–Features: Moderate hardness, high bulk density, without free silicon dioxide, good toughness, fine size and without ash.
- Application of sandblasting: stainless steel, iron workpiece, copper workpiece, glass product, plasthetics, aluminium extruded sections, Copper section, jean and special plus materials, plush processing and effect of pattern.
- Function: Remove surface stains, remove the welding slag and matt effect, remove oxide skin, surface strengthening, the role played by light.
- Sandblasting size: 46, 60, 80mesh(Big size could recycle more times. Or according to the customer’s request.)
- Grinding wheel—-When grinding high tensile strength materials, choice the good toughness
- brown fused alumina. When grinding low hardness with elongation of the material, choice brittle brown fused alumina.
- Coated abrasives and Bonded abrasives
