I've used my power miter saw to cut aluminum on many occasions. I use a 14" carbide blade that's intended for wood. I go slower than I'd cut wood. I use a feed rate that produces a nice thin chip. I'm sure it dulls the carbide faster than cutting wood, but it's not that bad. As was noted in the video, it's much faster than using the bandsaw, and it's easier to make accurate and repeatable rough cuts. I've cut thick pieces as shown in the video, but I usually cut 1-2 inch aluminum angle to make custom brackets. I dry cut the aluminum, mostly because I was too lazy to set up a mister.
I've thought about buying one of the similar looking multi cut saws such as the DW872 that cuts metal at a slower RPM. They can cut steel as well as aluminum. A good 14" blade is $100 and up, but the cost per cut is reported to be better than abrasive cutting wheels, and it's much faster than an abrasive cutuff saw or a bandsaw.
