Cutting aluminum

most times when i get heavy aluminum to cut i use the skill saw with a carbide blade ,....you have to be carefull ,know how to use a circular saw ,and really really have good eye protection ,....it's tricky ,dangerous and dulls the blade ,but a good carbide blade will zip right threw aluminum ........disclaimer =....i often do things that would make an osha rep have a heart attack and often have to tell peaple "don't try this at home" ,....so use common sence
