white fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. WFA has higher hardness and slight lower toughness comparing with brown fused alumina. white fused alumina is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. As the abrasive materials, it is suitable for grinding high-speed, high carbon steel, as loose grains, it widely used for bonded and coated abrasives , polishing, precision casting and so on . Furthermore, our company , HENAN RUISHI SPECIAL REFRACTORY CO., LTD. is established according to the modern management in 1993. As one of the main manufacturers and exporters for abrasive, refractory materials and metallurgy industry in China. We have six plants (One Fused Plant ,Three processing Factories, One Special Refractory material plant,One metallurgy material Plant,One Acid washing and Water washing plant, and Sales Department ).We can produce 80,000 tons annually. Our products are main exported Italy, France, Russia, American, Japan, Spain ,Canada ,Korea and so on. Our products include Brown Fused Alumina95%, Brown Fused Alumina98%,White Fused Alumina, Black Fused Alumina, Compact Fused Alumina, Semi-Friable Fused Alumina, Micro Crystalline Fused Alumina, Calcium Aluminate etc. white fused alumina chemical composition: Al2O3:99%MIN Na2O:0.5%MAX CaO:0.5% MAX Magnetic material content(%):0.003 %MAX We have strict control about company & quality;Our service is full-around and first-class.
