Brown fused alumina is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2200°C. A slow solidification process follows the fusion, to yield blocky crystals. The melting help in removing residual carbon , Strict control over Titania levels during the fusion process ensures optimum toughness of the grains. Then 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.

White aluminum oxide is a high purity abrasive electrically fused from Bayer processed alumina. This product is ideal for applications that require minimal foreign contamination or higher friability than regular brown fused aluminum oxide.

Pink Fused Aluminum Oxide contains chromium oxide, which gives the material its pink color. The incorporation of the Cr2O3 into the Al2O3 crystal lattice produces a slight increase in toughness and a reduced friability compared with White Fused Alumina. Compared to Brown Regular Aluminum Oxide the Pink material is harder, more aggressive, and has better cutting ability. The grain shape of Pink Aluminum Oxide is sharp and angular.

Black Silicon Carbide is produced in electrical internal resistance furnaces from high purity silica sand and petroleum coke. Its combination of being very hard and sharp makes it a very aggressive abrasive ideal for many applications. Black SiC is typically used on hard or brittle materials. It is also used for kiln furniture, lapping and polishing, non-woven, tumbling, pressure blasting, anti-skid, electrical heating elements, aerospace, composites, etc.

The extremely fine crystalline microstructure allows for one of the most durable materials in the abrasives industry, outperforming commodity abrasives like brown fused aluminum oxide and silicon carbide. The most common applications are in bonded, coated and cut-off wheel applications, like grinding of stainless steel.

A natural occurring odorless mineral having its broadest use as an abrasive in polishing applications. An intimate mix of corundum and magnetite. The higher amounts of impurities and weaker internal structure than naturally occurring minerals has restricted its growth in new applications. Emery is widely used in manufacturing of coated abrasives like emery cloth & emery paper. The typical self sharpening action of the emery grains with needle shaped grains and uniform grading make emery grains the first choice for use in this application.
