I would think a penetrating oil would work fine on its own. We use PB Blaster for iron-based alloys/steel/etc. For bronze-to-bronze things (like rigging screws) we use a thinned lanolin oil, though. Aluminum often "welds" itself nicely to things and thus you might find that heat is useful if the penetrating oil by itself just doesn't do the trick.
