BROWN ALUMINUM OXIDE (A)
Brown Aluminum Oxide 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 sharp shape in size.It is used to grind metals of high-tensile strength such as steel, annealed malleable iron and hard bronze.
It can also be used as high-class refractory.
