Item # 15-MA, Micro Alumina Precision Lapping Powder

Manufactured from 99+% calcined alumina, our Micro Alumina is an ideal abrasive for lapping semiconductor materials such as silicon, gallium, and germanium, quartz crystals, precision optical materials, glass and plastic lenses for prescription eyewear, stainless steel, aluminum and many other materials requiring an extremely fine, scratch free, uniform finish. Ideal for coated and bonded products, wear resistant surface coatings and thermal spray applications. Each particle is a discrete crystal, plate shaped to yield finer finishes than other conventional lapping abrasives, water-classified into specific micron sizes by our unique, continuous, automated grading process that assures consistent and predictable results
