I used to make a product for a company that involved cross cutting corrugated aluminum sheeting, 11ga thick. We used an aluminum blade in a worm drive Skilsaw. Cut great. We could get maybe a few hundred linear feet of life out of a blade before aluminum would start to build up on the blade and cause binding. Since these were welded in a fussy fashion, we didn't want to be adding any sort of lubricant that could mess with the weld.
In general, a squirt of WD-40 or some stick wax works wonders for blade life and chip release.
Just about any woodworking tool will cut aluminum if it has a carbide blade. HSS will do it too, just not as well or for as long.
We use routers all the time to put radii and chamfers on aluminum bar and tube.
The rules are the same for any kind of metal cutting. Use appropriate feeds and speeds. Cut with lubricant or coolant of some kind if possible. Use sharp tools. Wear hearing and eye protection. Be prepared for the tool to grab and cause problems. Hold the work as well as possible.
