The spelling with more legitimacy is Aluminum.
Sir Humphrey Davy, its discoverer, called it Aluminum when he published his work Chemical Philosophy in 1812.
Some anonymous dilettante (anonymous to this day!) thought, upon reviewing said book, it sounded better (more classical) with the extra I and syllable.
Everybody calls Aluminum's oxide Alumina, not Aluminia.
Nobody else seems to feel the need to rename Platinum Platinium, or Molybdenum Molybdenium, or Tantalum Tantalium.
We Americans too often like to mock other cultures for being different, and our basis is usually wrong when we do. Maybe mocking our pronunciation and spelling isn't a habit you want to hold on to.
