Brown fused alumina are the perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, and lapping and polishing processes. While aluminum oxide has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important. 25kg/bag+1mt jumbo bag

Black silicon carbidedescription Black silicon carbide is produced at high temperature in an electric resistancetype furnace with quarts and petroleum as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused fused alumina. It is brittle and sharp and has electrical and heat conductivity in some degree. The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive. Company introduction Our company was established in 1976, is a famous manufacturer of abrasive powder in china. Our company supply types of abrasive, including black silicon carbide, white fused aluminum oxide. The specification and f, p, jis standard graded powder is available on request.
