First Quality Brown fused alumina

Brown fused alumina 1.excellent quality, 2.resonable price 3.good services

Brown fused alumina is made from high quality bauxite by fusing in an electric arc furnace at high temperature. It has good toughness and high hardness. It is suitable for manufacturing of vitrified and resin bonded tools(FT-GW,FT-HBD,FT-MCL,FT-HCL,FT-PBFA,FT-PCBFA) and for lapping polishing and sand blasting(FT-BL,FT-InHBL). It can be also used to make superior refractory products(FT-RF,FT-Collecter)
