Chemical Composition of Brown fused alumina:
Al2O3: 95% MIN
Fe2O3: 0.3% MAX
SiO2: 1.2% MAX
TiO2: 3.0% MAX ...
Brown Fused Aluminum Oxide for sandblasting
Specification:
1. High hardness
2. High toughness
3. Resistance of high-temperature
4. Anti-oxidation
5. Corrosion resistance
Brown fused alumina oxide is made by using bauxite, coke (anthracite) as raw materials, smelting in electric arc furnace at high temperature. The main chemical compositions are Al2O3,TiO2 and little SiO2,Fe2O3 and so on. Hardness HV1800-2200,higher toughness than Sic. The abrasive made from it is suitable for high tensile strength metal, such as a variety of common steel, malleable iron and hard bronze. It also can be used to the advanced refractory.
1. For abrasive production(Coated abrasive and Bonded etc.)
2. For refractory materials
3. For sandblasting abrasive
4. For abrasion resistance ground
5. For producing mold of precision casting
