Brown fused aluminium oxide is a tough, hard, and chemically inert material with high thermal conductivity.It is commonly used as a blasting media for surface preparation, cleaning, and finishing of metals and other surfaces. Its high hardness and toughness make it ideal for use in grinding wheels, cutting tools, and abrasive papers and cloths.
