K. C. Abrasive’s Aluminum Oxide powders feature uniform, precision grades that are vital for precision lapping, grinding, compounding or blasting applications. The durable, blocky crystal structure is ideal for micro blasting such items as silicon wafers and dental castings. It is also used for close tolerance lapping of various types of metal parts such as seals, piston rings and pump housings. It can be used for plasma spraying to build a wear resistant surface. Our aluminum oxide powder is “wheel makers quality” and is ideal for bonded abrasive products such as precision honing stones and grinding wheels. These powders are suitable for specialty coated abrasive products.
