brown aluminum oxide

Product Description

Brown fused alumna is fused and crystalized under high temperature from a mixture of bauxite 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 ad hard bronze, etc. It also can be used as refractory materials.
