I may be crazy, but, I thought aluminum doesn't rust. Am I mistaken?

Don't assume that because you have found one problem, you have found the
ONLY problem.

The problem with using a patch of metal different from the original floor
is that you set up 'dissimilar metals corrosion' which can be much more
agressive that regular rust. Has to do with the electron valances (sp?)
being different for the two metals (the original steel and the new
aluminum), I think. Regardless of the cause, I've seen it in cars and
airplanes. In this instance, your aluminum patch will probably corrode
pretty quickly. Not the end of the world, but when you replace the aluminum
patch (heck, could be years from now), try using a steel plate if you can
get it. I did the aluminum patch thing with an old VW. Only lasted a year
in Rhode Island.
