White fused alumina is made in arc furnace with high grade processed alumina as raw materials. It has higher hardness , high toughness, and also characterized by its high purity. As the abrasive materials, it is suitable for grinding high-speed, high carbon steel. also widely used for bonded and coated abrasives, polishing, precision casting and so on.  

—Description The WFA is the main raw material for the production of unshaped and shaped refractory materials. Commonly used in ladle castables, iron runner materials, refractory gunning mix materials and other monolithic refractory products; For the shaped refractory materials, it is mainly used in the high-quality raw materials of corundum brick, corundum mullite, refining steel

Aluminum Oxide AL2O3 have the characteristics of high hardness (second hardest mineral after diamond), sharpness, tenacity, stable chemical property, heat resisting and corrosion resisting, This sharp angular abrasive is fast cutting and is silica free. It gives a matte finish, or produces anchor patterns on most metal surfaces and can be used economically in a

white fused alumina is produced by fusing pure alumina in electric arc furnaces at the Boksitogorsk Alumina Refinery. Due to its ultra-high strength, white fused alumina is used for producing abrasive tools, and because of its resistance to high temperatures and low thermal and electrical conductivity, is in the production of ceramic and refractory products.

WA – White Fused Alumina WA is a fused white alumina abrasive powder produced by crushing fused alumina and sorting the particles into a uniform size. The resulting compound has the following characteristics: An α‑type corundum crystal configuration At least a 96.0% pure aluminum oxide (Al2O3) composition A hardness nearly equal to silicon carbide A closely
