brown aluminum oxide grit 220

Brown Alundum

Brown Alundum is produced by the fusion of calcined bauxite in an electric arc furnace at over 2000 centigrade. It stands out due to its very high toughness, so that it has a long lifespan, but cool cutting is not expected. By these characters, it widely uses for working on regular steel, carbon steel, forging steel, ingot steel, cast iron, and malleable iron, as well as some non-ferrous metals.
