ISO Certificated Natural Brown Corundum/ Aluminum Oxide for Abrasive/ Refractory
Brown Corundum
Brown Corundum is also called Brown Fused Alumina/ Brown Aluminum Oxide, it is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness, good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel, general-purpose alloy steel, annealed malleable iron and hard broke, etc. It also can be used as refractory materials.
