Blasting Abrasives
White Aluminium Oxide
It consists of pure alumina with no traces of iron, so it causes no oxidation of the blasted parts.

Characteristics of white aluminium oxide
- It consists of pure alumina with no traces of iron — which is why it causes no oxidation of the blasted parts.
- It is used mainly by dental technicians and in the food industry, but also in aerospace applications.
- A high-performance aggressive abrasive that keeps its angular shape even after repeated use.
- A recyclable abrasive and particularly hard (8-9 on the Mohs scale).
- Thanks to its high hardness and its angular shape, it can reach SA-3 roughness very quickly.
- Depending on the grain size and the blasting pressure, we can achieve a wide range of surfaces with the roughness we want.
- Working at constant pressure, we achieve an ideal surface with the right roughness for coating.
- It is completely safe for people, unlike many other blasting abrasives.
- It contains no silica, which is harmful to people.
- It contains no toxic constituents such as heavy metals.
