Descrizione del prodotto

Our polishing aluminas are grades of a specially produced oxide. As inorganic products, they have one important advantage over natural materials used for polishing: their physical properties and chemical compositions are constant regardless of the pressure or temperature experienced during use. Aluminum oxide is the most widely used polishing medium. In general, polishing compounds contain approximately 50% alumina. The primary crystals of Almatis polishing aluminas are extremely hard. On the Mohs scale the aluminas rate one degree below diamond.
