Aluminum Oxide Blasting Media

About aluminum oxide blasting media

Aluminum oxide is a finely ground ceramic particle, often 50 micrometres, used for airborne-particle abrasion of metal castings before porcelain is applied. Air abrasion with alumina is one of the most common ways of improving the mechanical retention of materials.

Sharp and hard.
