Semi Friable Brown Fused Alumina is a new type of Abrasives Aluminum Oxide with bauxite as raw materials and in the base of smelting vice white fused alumina under 2100 celcius degree.By controlling ratio of the raw materials and smelting process, you get harder and tougher new type abrasives material. With sharp edges, stronger and tougher restance against abrasives, errosion and corrosion, better chemical and thermal stability, Semi Frable Brown Fused Alumina is widely used in higher quality coated and bonded abrasives.
