High Grade White Corundum
High Grade White Corundum belongs to the group of electro-corundum.White Fused Alumina is produced by fusing calcined alumina in an electric arc furnace under carefully controlled conditions at high temperature. The dense mineral is white in color, and has predominantly large crystals of Alpha Alumina.White fused alumina is iron-free, ultra pure and extremely hard. Grinding Wheel WFA
White Corundum (WFA or WA) is an important raw material for advanced refractories and abrasives, a widely used raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding, and hundreds of other applications. As it is a very pure, low iron alumina, specific refractory applications include high tech refractory castables, isostatic pressed refractories, and pre-cast refractory shapes. The benefits of White Fused Alumina in these applications are high alumina content, low impurities, and stability at high temperatures. Grinding Wheel WFA

1, does not affect the color of the workpiece; 2, can be used in the process of iron powder is strictly prohibited to blasting; 3, fine powder level is very suitable for wet sandblasting and polishing operations; 4, high processing speed and high quality; 5, contains a very low amount of iron oxide is strictly prohibited for the residual sand blasting operations; 6, after pickling step to remove impurities.
BFA & WFA
Both basic mineral: α-Al2O3 Both PH Value: Neutral Both Max.usable temperature in air is 1900 Celsius degree, decomposition point is 2250 Celsius degree. Both main chemical composition of finished products are: Al2O3 Both main applications are: in refractory and abrasives products. Both Mohs hardness are: 9.0
BFA bulk density is (1.53~1.99g/cm3) and true density (3.90g/cm3). While WFA bulk density (1.75~1.95g/cm3) and true density (3.95~3.97g/cm3). Main raw material of BFA is bauxite, and main raw material of WFA is calcined alumina powder. BFA has Al2O3 content of 95% Min., WFA has Al2O3 Content of 99% Min. BFA has refractory temperature 1850 Celsius degree, WFA has refractory temperature 2100 Celsius degree. Although their Mohs hardness is 9.0,WFA is even harder than BFA, and BFA is more flexible than WFA.
