Also, the other poster is maybe confusing Magnesium with Manganese? Magnesium will tarnish very quickly (basically instantly on exposure to air) but keeps the process from converting the whole block of magnesium by the means of Self Galvanization. The thin layer of magnesium oxide keeps the rest of it from reacting with air, and is somewhat resistant to rubbing off. Manganese however will act somewhat similarly, but is far more prone to flaking off from what I remember.

I think aluminum does the same thing. Yes No?
