Aluminium Oxide Al2O3
Aluminium is protected by a layer of it's own oxide (Aluminium Oxide Al2O3). Aluminium does not rust or corrode under moist conditions, because it's surface is covered with a thin layer of aluminium oxide that prevents the metal underneath it to come in contact with the moisture in the atmosphere.
