Almost certainly aluminium oxide. There are a number of possible
solutions but the oxide itself actually forms a semi-protective coating
itself. Once the oxide forms it does not (unlike rust on steel) continue
to eat away at the substance of the metal.
You can try polishing it up and then coating in clear laquer or
aluminium based paint - or simply leave it as it is.
