Brown Aluminum Oxide HS Code 28181010, CAS No. 1344-28-1, is a tough, sharp abrasive which is highly suitable for grinding metals of high tensile strength. Its thermal properties make it an excellent material for use in the manufacture of refractory products. This material is also used in other applications like blasting and surface hardening.
