Aluminum Oxide is among the hardest blast abrasives available. It is also a top choice for applications that must avoid contamination or corrosion. Aluminum oxide can be used to blast many different substrates including metal, glass, and wood, and is mainly used for etching and finishing.

The terms mean generally the same thing: the removal of the top layer of a substrate, coating, contaminant, or corrosion through airborne abrasives.
