We all know that brown corundum abrasives are widely used in the market, but there are also many people who have consulted many questions, such as "What is the chemical composition and content of brown corundum abrasives"

　　The main chemical component of brown corundum is AL2O3, with a content of 94.5%-97%, and a small amount of Fe, Si, Ti, etc. Brown corundum, commonly known as emery, is a brown artificial corundum made from bauxite, carbon material, and iron filings through melting and reduction in an electric furnace, hence the name. Abrasives made of brown corundum are suitable for grinding metals with high tensile strength, such as various general-purpose steels, malleable cast irons, hard bronzes, etc., and can also be used to make high-grade refractory materials. Brown corundum has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient and corrosion resistance. It has been verified by dozens of refractory manufacturers that the product has the characteristics of non-explosion, non-powdering, and non-cracking during the application process. In particular, its cost performance is much higher than that of traditional brown corundum, making it the best aggregate and filler for brown corundum-based refractories.
