Product introduction
Brown corundum, common name also known as emery, is made of bauxite, carbon materials, iron filings three kinds of raw materials in the arc furnace after melting and reduction of the brown man-made corundum, so this name. The main chemical composition of brown corundum is AL2O3, its content in 95.00%-97.00%, and contains a small amount of Fe, Si, Ti, etc. Brown corundum is the most basic abrasive, because of its good grinding performance, a wide range of application, cheap, has been widely used.
