Aluminum Cuts like wood. Be careful though. The miter saw instructions you give precautions to follow for a given blade does not catch the metal (the part that is cut) and round like a ball on the back side of the saw. I have not read / follow the instructions of my saw, (and has learned the hard way).
This blade is worth every penny. I bought one of those at the lumber yard, I work at (where Ace Hardware is stored) and I love it. I use it in my Bosch 4212L 12-inch Dual Bevel Compound Miter Saw with Laser Tracking. It is robust and works silently. I'm not sure, however, if it can be reteethed. I should also note that this blade has 3 different teeth while most have only two. Rather than having only left and right teeth, this blade has teeth left, right and center. Iurges everyone. It cuts so easily that you never have to sand again.
