F20 F22 Brown Fused Aluminium Oxide Magnetic Materials 0.02% Max Deep Blue Color
Brown Fused Alumina is fused and crystallized under the high temperature of above 2250°C with high quality abrasive bauxite as raw material.It is characterized by good self-sharpening and high grinding ability. Brown Fused Alumina can produce ceramic grinding wheel ,resin grinding wheel.And BFA could be used for abrasive,sandblasting and precision casting
Brown fused alumina for refractory advantages:1) High quality bauxite as raw material
2) Refractory temperature is more than 1900°C
3) No burst,no pulverization and crack in the using course of refractory
4) Very low amount of iron oxide
5)High purity
Brown fused alumina for Abrasive SandblastingPrecision casting advantages:1) Not affecting the color of the processing cases.2) Sandblasting in the non-iron process.3) High speed processing.4) Very low amount of iron oxide, suitable for non-ferrous blasting
operations.
5) Easy to shell
