How fast does aluminum oxidize

WebTwo oxidation reactions, that occur when molten aluminum comes into contact with air, proceed as follows: 2Al + 3H 2 O → Al 2 O 3 + 3H 2. 4Al + 3O 2 → 2Al 2 O 3. Hydrogen, in turn, dissociates into its atomic form on the surface of the melt, and then diffuses through the film of amorphous alumina and then quickly dissolves in the aluminum melt.
