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.

FEATURES IN SANDBLASTING
Higher hardness
Strong cutting force
Good chemical stability, acid and alkali resistance
Iron-Free
Wet or dry or sandblasting
- Iron workpiece rust removal, decontamination, descaling, large coating, coating adhesion;
- Aluminum workpiece descaling, surface strengthening, glazing effect;
- Copper workpiece deoxidized leather matt effect,
- Glassware crystal frosted, engraved pattern
- Matte effect of plastic products.
After blasting, the surface is white and free of any impurities, eliminating the need for cleaning.
