1. Brown Fused Aluminahslabrasive
^ 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.
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.
4. Production Technical Process
Raw Material Selecting → Electric Smelting → Crushing → Iron Removal by Magnetic →
Screening → Inspection of Physical and Chemical → Product Packing → Warehousing
5. Package & Shipping
^ 25kg/bag, 1000kg/JUMPO bag ; Customerization Allowed.
