with high quality alumina oxide powder as raw materials, white fused alumina is produced by fusing and extracting from crystallization. it is featured by high purity, self-sharpening, and acid-alkali and corrosion resistance, temperature tolerance. compared with brown fused alumina, its thermal stability properties is slightly higher and toughness is slightly lower. the abrasive tools made of it are applicable for grinding high carbon copper and high-speed steel. 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 .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. so we¡¯re you wise choice.don¡¯t hesitate to contact us contact person: ms. liang xiaofei(sales manager) helen(at)rs-abrasive.com tel:+86 379 65285888-0 13015581246 fax:+86 379 66285889
