Excellent question.  "Chop saws" have abrasive blades and are actually
grinders.  You cannot use chop saws for aluminum for the same reason
that you can use a grinding wheel for aluminum.  For aluminum, I use a
mitre saw intended for wood, but with the non-ferrous blade.  You can also
install a ferrous blade in the mitre saw and use it for steel.
