Brown Corundum Brown Fused Alumina (BFA) for Grinding toolsPRODUCT DETAILS 1. Brown Fused Alumina
^ Brown Fused Alumina is made from bauxite and coke (anthracite) , through melting
at high temperature in electric- arc furnace. The range of general granularity size is
F4 ~ F320, its chemical composition varies depending on the size of the particle.
^ The outstanding characteristic is the small crystal size & impact resistance, due to the
using of self-grinding machine to process and crush, most of particles are spherical, dry
and clean surface, easy to bond to bond agent.
2. BFA Applications
( Due to its usable range, brown corundum is called the teeth of industry: mainly used in
grinding wheel, sandblasting, and material resistance )
^ Mainly used for precision casting, wear - resistant materials, industry which have higher
requirements of abrasive materials.
^ Mainly used for sandblasting, polishing, grinding, corrosion resistance and rust removal,
stone carving, gauze material, cutting pieces, etc.
^ Also be applied to all kinds of flooremery required by the ground, such as airport runway,
playground, and factory wear - resistant ground.
3. BFA Parameter
The main compositions of BFA are Al2O3, TiO2 , a small amount of SiO2 , Fe2O3, and etc.
True density 3.85g/cm3, Hardness 9 , Higher toughness than Silicon carbide.
The grinding tools made of it, are suitable for grinding metals with high tensile resistance.
In addition, BFA can be also manufactured refractory materials.
