brown fused alumina is good raw material for castable refractory, it has high density. strong hardness.
brown fused alumina character:
brown fused alumina is fused and crystallized under high temperature from a mixture of bauxite and other materials. It is characterized by its high hardness, good toughness and sharp shape in particles. Suitable for grinding metals of high-tensile strength such as carbon stele, general purpose alloy steel, malleable cast-iron and hard bronze etc.
