Alumina Refining | The Aluminum Association

In addition to its use in the production of primary aluminum, aluminum oxide has other key industrial uses. Alumina is often used as a filler for plastics. The compound is also widely used as an abrasive and is a less-expensive substitute for industrial diamond. Aluminum oxide flakes produce reflective effects within the paint used on automobiles.
