The wire machine will cut most anything that conducts electricity (including your hand - it's not as severe as an auto coil, but it will definitely get your attention).
Cutting speeds very but in a nutshell, the more conductive the material is, the faster the machine can cut. And, in disagreement with the previous poster...this type of machine flies through aluminum. In "typical tool steel"...12 to 17 square inches per hour would be the maximum even though the manufacturers will advertise much faster (in a lab with ideal conditions with the full moon over scorpio, etc.). 12 to 17 inches per hour translation?...IF your material is 1" thick, expect the machine to be able to cut a line (no skimcutting) 12 to 17 inches long. Aluminum?...40 to 50 per hour. The drawback with aluminum however...very dirty with larger than normal debris that plugs up the water filters very quickly.
