Following the advice of TP Tools, I used black iron. 3/4" for the main lines and 1/2" for the drops, I used the TP Tools diagrams and have never had a problem with rust or scale or anything like that. I drain the water traps each morning and again each evening after I quit work. Each drop uses an Ingersall Rand regulator and filter. I have one drop that's dedicated to paint and powder coat and that drop also uses a coalescaling filter with a replaceable cartage element and a small inline filter at the gun.
I wouldn't recommend copper pipe, the soldered joints can fail and it is subject to damage because it's relatively soft.
Here's what TP Tools says about it:
Use Black Iron Pipe only. We do not recommend galvanized metal pipe, as galvanization can come off the inside of the pipe, clogging separators and regulators. Do not use PVC pipe, as PVC will not help cool the air; and glued joints often separate. Avoid copper tubing, as it is easily damaged; and soldered joints can come loose under pressure (Safety Hazard).
