I opened up a soda can back when I first got my laser, back in the time when I'd put anything in there just to experiment. I ran a 3/4" diameter circle, 100% power, several times. The heat of the laser hitting it caused the metal to form a slight crease, resulting in a rounded dimple... but other than that it won't cut aluminum. It does open up some possibility of interesting techniques though, using the uneven heating to form patterns.
