Al2O3 99% Iron Free White Aluminum Oxide Abrasive Sandblasting Trigonal Crystal System

WHITE ALUMINUM OXIDE FOR SANDBLASTING

White aluminum oxide is made from industrial alumina powder by modern new unique technology, smelting at a temperature higher than 2000 degrees, and is cooled, pulverized and shaped, magnetically removed to iron, and sieved into various particle sizes. The blasting abrasive has the characteristics of dense texture, high hardness, short grinding time and high efficiency. The main component: Al2O3 (Al2O3) content is above 99%, and contains a small amount of iron oxide, silicon oxide and other components. It is an ideal blasting media, usually using mixed with glass beads for sandblasting.
