Why can aluminum resist corrosion?
When exposed to air the surface of a piece of aluminum will oxidize and form a coating of aluminum oxide, known in its mineral form as corundum. Aluminum oxide is one of the hardest substances on Earth and so protects the aluminum from further oxidation. It is possible to get aluminum to corrode. Mercury will prevent the oxide from forming a protective coating.
