Product Description:

Al2O3 Brown Aluminum Oxide Ceramic-Bonded Abrasives For Industry


Brown Aluminum Oxide, also called brown fused alumina, is an industrial alumina powder with good self-sharpening characteristics. It is made of high-grade bauxite, carbon materials and iron filings through melting in an electric arc furnace. The main component of it is Al2O3, and its content is up to 95% or more. Brown Aluminum Oxide is a trigonal crystal system, and its hardness is greater than corundum. It is suitable for applications such as grinding, lapping and sand blasting. This industrial alumina powder is also suitable for ceramic-bonded abrasives production.


Brown Aluminum Oxide has the ability to resist high temperature, corrosion and erosion, and its melting point is up to 2250°C. It is also a high-grade refractory material with good thermal shock resistance, heat conduction, wear resistance and high insulation. It is widely used in abrasives, sandblasting, precision casting, refractory materials and other fields.


In addition, Brown Aluminum Oxide has strong hardness and toughness, and its grinding and polishing effect on metal and non-metal is very good. It is widely used in grinding and polishing of optical glass, electronic products, automobiles and ships. It can also be used for sand blasting of metal and non-metal parts, and for production of grinding tools for grinding and polishing of metal and non-metal materials.
