Brown fused alumina micro powder is essential for precision grinding, polishing, compounding, and sandblasting applications due to its uniform and precise grading. Its blocky crystal structure makes it perfect for micro-blasting tasks like silicon wafers and dental castings. It is also used for precise lapping of metal parts with tight tolerances, including seals, piston rings, and pump housings. Additionally, it can be used for plasma spraying to create a wear-resistant surface. This micro powder is suitable for bonded abrasive products such as honing stones and grinding wheels, as well as specialized coated abrasive products.
