I recently use my table saw to cut a bunch of 3/4” aluminum for my CNC router build. I got a blade from Amazon for around $20 that they said was good for cutting aluminum. It was an 80 tooth negative rake. First cut was great, but after that, I had to stop every couple of inches to clear the slag out from between the teeth. So I got one of those saw blade lubricant sticks and that helped immensely. Still had to go slow, but the cuts were nice and clean. Like others mentioned, the chips are very hot and tend to fly up straight at your face. Be sure to use goggles. I had mine on but a piece still found its way underneath them and into my eye. Not very comfortable. Still have the scar where another piece hit me just under my left eye and got stuck to my skin.
