If you've got as much crap as those magnets picked up in that picture you've got some serious issues.....

Any ferric (iron containing) material, or any thing like cobalt, nickel (the only metals that are capable of magnetism) will be picked up. My guess is that those contaminants will also trap aluminum simply because of the way oil is going to be pressed against the piles that will eventually accumulate.
