Aluminum oxide grit (or aluminium oxide) is an angular, long-lasting blasting abrasive that can be recycled numerous times. Because of its low cost, durability, and hardness, it is the most commonly used abrasive grain in sand blast finishing and surface preparation. Aluminum oxide grit powder, which is harder than most regularly used blasting powders, penetrates and cuts even the hardest metals and sintered carbide. SBM provides all type of Aluminum oxide grit alike 120 grit Aluminum oxide, 100 grit aluminum oxide blast media, black aluminum oxide 70 grit, 80 grit aluminum oxide blast media, White Aluminum Oxide Grit, aluminum oxide 220 grit, etc in India at a low price.
Aluminum oxide is a cost-effective and efficient grinding and polishing media for tumble operations that require rapid edge rounding, surfacing finishing, or cleaning.
Aluminum oxide abrasive grain is approximately 50% lighter than metallic media and has twice as many particles per pound. By minimizing surface tensions induced by heavier, slower-cutting media, the fast-cutting motion avoids damage to thin materials.
Because virgin aluminum oxide, brown aluminum oxide contains less than 1.5% free silica, it is safer to use than sand. The grit size is uniform and cuts much faster than sand, resulting in a more smooth surface. In general, the higher the grit size, the faster aluminum oxide cuts.
On the basis of color, there are three types of aluminum oxide grit available:
- White Aluminum Oxide Grit
- Brown Aluminum Oxide Grit
- Black Aluminum Oxide Grit
White Aluminum Oxide Grit
White aluminum oxide grit is friable (how easily/quickly an abrasive media smashes/shatters on impact and breaks down, resulting in low dust generation). This is distinct from the Hardness Rating. Sand blasting medium with the same hardness rating but vastly differing friability ratings can exist. Friability is synonymous with durability; medium density abrasives are also available in a variety of grains, including coarse, medium, fine, and powder.
Brown Aluminum Oxide Grit
The maker of Brown Aluminum Oxide employs high-grade aluminum and modern processes. Our vendors test it on many aspects to ensure its quality. Brown fused aluminum oxides are recommended for use in bonded abrasives such as grinding wheels and cutoff wheels, coated abrasives (paper & cloth), sand blasting abrasive media, and refractory applications due to their high hardness.
Black Aluminum Oxide Grit
One of the hardest minerals available is the black aluminum oxide, grit maker. The electrofusion of bauxite, iron oxide and tiny components during a shifting circular segment heater produces black aluminum oxide. Manufacturer of black aluminum oxide grit that is insoluble in water. Corundum, or -aluminum oxide, is the most often occurring transparent structure. Its hardness qualifies it for use as a grating and as a component of cutting tools. To endure, black aluminum oxide is on its way to the obstruction of metallic aluminum. It is frequently offered in sizes ranging from grains to micro powders and is one of the most important conservative media accessible for a wide range of dry and wet handling applications.
