Brown Fused Aluminum Oxide
Brown Fused Aluminum Oxide also called Brown Fused Alumina, Brown
Aluminum Oxide or Corundum (BFA) is produced by the fusion of
high-quality bauxite in an electric arc furnace at high
temperatures. Our Brown Fused Aluminum Oxide has high compression
strength, high toughness, excellent self-sharpening, low
coefficient of thermal expansion, and excellent hydrophilia and
cleanliness. Brown Aluminum Oxide is a clean, high-strength
material that resists oxidation and corrosion, maintains chemical
stability, and withstands extraordinarily high temperatures.
Becens s brown fused aluminum oxide is made into many Grade, shapes
and grit sizes for difference application.
Beside of coarse and micro powder Brown Fused Aluminum Oxide, it
also have deep-processing BFA as follows:
Calcined Brown Fused Aluminum Oxide-1050℃
The functions of medium temperature calcined:
1) SiO2 has a lower expansion coefficient than Al2O3, it can make
SiO2 inflate at the medium temperature calcined, and then reduce
the cracks in the production of Brown Fused Aluminum Oxide ceramic
2) Under the high temperature, the impurities will be separated out
or vaporized, and then improve purity.
3) After calcined, the micro-cracks which brought in the breaking
process can eliminate, thus greatly improving Brown Fused Aluminum
Oxide grits toughness, strength and enhancing the wear resistance
of the abrasives.
Main applications: high quality vitrified grinding wheel
Blue Fired Brown Fused Aluminum Oxide-1350℃
Besides the advantages of medium temperature calcined, it can make
low titanium into high titanim, thus change the sand color to blue,
improve BFA grits toughness, the content of TiO2 is between 2.2 --
FEPA-P: high quality coated abrasive, such as sand paper, abrasive
belt and so on.FEPA-F: heavy loaded grinding wheels.
Ceramic Coated Brown Fused Aluminum Oxide
The functions of ceramic coated:
The coating can increase the hydrophilicity of grains and make them
bond firmly with adhesives.
Ceramic Coated Calcined Brown Fused Aluminum Oxide
Ceramic Coated Blue Fired Brown Fused Aluminum Oxide
It have both advantage of ceramic coated and calcined.
Main used for high quality cutting discs.
Brown Fused Aluminum Oxide is used for many app:
