Alumina sand (corundum sand) is one of the most economical abrasives for both dry and wet production processes. It is especially suitable for the treatment of rougher workpiece surfaces, while the treated surfaces require finer surfaces. This sharp, angular synthetic material is second only to diamond in hardness and is often used where iron contamination is critical. It can cut very hard materials or be spherical to process extremely precise workpieces to achieve extremely low roughness. Its high density, sharp, angular structure makes it the fastest cutting abrasive.  

Brown corundum is made by fused high quality bauxite, while high quality aluminate is used to produce powdered corundum and white corundum. Their natural crystal structure makes them high in hardness and fast in cutting performance. At the same time they are often used as raw materials for bonded abrasives and coated abrasives.

Corundum sand can be recycled in standard blasting equipment, the number of recycling is related to the material grade and the specific process.
