The problem with using galvanized or black pipe is that the pipe rusts internally and then the rust gets into your tools. There's no way to keep condensation out of the pipe system unless you have an expensive "dryer"....
1/2" Copper tubing - schedule M - has an internal working pressure rating of 387 PSI (M is the thin wall stuff). Our little home compressors aren't capable of making that kind of pressure - So I think it's pretty dang safe.
My personal shop is all plumbed in 1" L rated copper tubing (main lines).
