Brown Fused Alumina abrasive is electrically fused in an arc furnace from a mixture of bauxite, coke (anthracite) as main raw materal at high temperature.

It's chemical composition contains

Al₂O₃, TiO₂, and small amount of SiO₂, and Fe₂O₃, etc,.

Microhardness:1800-2200 kg/mm²,

toughness higher than silicon carbide.

Abrasive articles made of it is suited for grinding metals of high-tensile strength such as steel, annealed malleable iron and hard bronze etc..Browm fused alumina can also be used for making high-class refractory products.
