Product Overview

Description

Brown aluminum oxide grit/grain/fines/sand/powder in abrasives

Brown aluminum oxide grit/grain/fines/sand/powder in abrasives is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2000°C. A slow solidification process follows the fusion, to yield block crystals. Strict control over Titania levels during the fusion process ensures optimum toughness of the grains.The cooled crude is further crushed, cleaned of magnetic impurities in high intensity magnetic separators and classified into narrow size fractions to suit the end use. Dedicated lines produce products for different applications.

Brown aluminum oxide grit/grain/fines/sand/powder in abrasives is a tough, sharp abrasives 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.
