.........very corrosion resistant, very like Aluminum in that respect.

Actually, pure aluminium is very reactive (in the chemical sense). What makes it resistant to corrosion is the thin transparent layer of very stable aluminum oxide (Al2O3) that clings tenaciously to its surface. If this surface layer is penetrated or removed, then the aluminum is no longer resistant to corrosion.

For example, just place a sheet of aluminum foil in a mercury (II) chloride solution, then take it out and place it on a paper towel in the open air. Then the aluminum will crackle softly as it corrodes to give Al2O3 and a lot of heat will be liberated.
