There's
far more vibration in an engine bay than any building...and straight/elbowed soldered copper plumbing pipes are structurally very different than a little coiled tube with threaded or flared ends.
Anyway, even so, I would be reasonably confident with copper. Steel is usually stiffer/harder and fatigues worse than copper.
I just did a quick check on google but couldn't find a table of fatigue rate values for steels and copper.
