David is correct.
DampRobot (real name/team # would help), even with coolant and such. 6063 is gummy stuff. Its also weaker and will bend easier. You can easily crush it in a vise (while true with 6061, its a bit harder). I'd steer clear away from it.
What are you looking at that you can't get in 6061?
