Product Description

          BROWN FUSED ALUMINA GRITS FOR BONDED ABRASIVES

Brown fused alumina is made by fusion in an electric arc furnace from a mixture of bauxite, anthracite and iron scraps at high temperature. It has brown color, high hardness and great toughness. No rusty spot, greatly improved grinding efficiency, applicable to make high quality vitrified and resin bonded abrasives. suitable for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture high-grade refractories.Our production standard can be GB/T, also can be FEPA, JIS, ISO, etc.. according to clients' requirements.
