The Aluminum Oxide lapping film boasts a uniform and consistent finish that is achieved through the use of precisely graded minerals on a strong polyester backing. This unique combination allows for abrasives to be oriented and evenly distributed, resulting in a higher level of grinding efficiency and a superior polishing effect. The film is comprised of a variety of minerals, including diamond, aluminum oxide, silicon carbide, silicon oxide, cerium oxide, making it suitable for grinding and polishing a wide range of materials with varying degrees of hardness. Its versatility and effectiveness make it an ideal choice for those seeking a reliable and high-performing lapping film.
