Aluminum Oxide:It is the most common industrial mineral in use today. Fused aluminum oxide is produced synthetically by melting bauxite and additive in an arc furnace to form a fused aluminum oxide ingots, which are later crushed and sized. The various types of fused aluminum oxides are distinguished by the levels of chemical impurities remained in the fused mineral. Fused aluminum oxide is available in several variations depending on composition and processing.

White Aluminum Oxide:White fused alumina is a kind of synthetic mineral with a high purity. It is the most friable grain in the fused alumina family.

Silicon Carbide:Silicon carbide (SiC) is a synthetic abrasive that was first developed in the late 1800s. It is harder than aluminum oxide, but more friable than grains of fused aluminum oxide. Typically, silicon carbide is used with nonferrous materials such as brass, aluminum, or titanium. The high solubility of carbon and silicon in iron would cause silicon carbide to react with an iron base alloy and result in poor grinding performance. Levels and types of impurities distinguish the green and black forms of silicon carbide. SiC's sharp and easily fractured abrasive grains are used for abrading other non-metals such as the stone, glass, wood, and leather. Like diamond, silicon carbide is susceptible to oxidation at higher temperatures.

Zirconia Alumina:It is a high performance abrasive which possesses the unique attribute of great toughness and the highest durability. The material is also able to withstand very high temperatures without the loss of utility. It possesses a good resistance to corrosion.

Ceramic Aluminum Oxide:Ceramic Aluminum Oxide is a self-sharpening grit that outperforms aluminum oxide in terms of hardness, toughness and life when used under identical conditions. It’s a new type of abrasive that was first invented and applied in 1983 by US company 3M, since then a variety of ceramic aluminum oxides have been developed.

Mounted Points:Mounted Points (B4C) is a grey-black colored super hard abrasive with metallic luster. It is one of the hardest man-made materials available in commercial quantities and has a finite melting point which is low enough to make it easier for fabrication into shapes.

Natural Abrasives:Ceramic aluminum oxide is a long-lasting, tough, dense abrasive due to its micro structure. The extremely small micron size particles break off during grinding, producing multiple new cutting edges. As it stays sharp, especially when used in medium and high pressure operations; it cuts at a higher rate than other abrasives. Recommended for use on difficult operating materials, such as aeronautic alloy, carbon steels high nickel steel, etc.

Combination:It refers to mix several kinds of abrasive grains together.

Specialty:Other specialty, proprietary or patented abrasive grain, grit or abrasive material.
