I think brass is the very best..or at least it use to be. Plain metal will corrode out sooner than brass. I don't know these days, maybe there are some better types..like Stainless steel or Kriptonite...?

PS. If the plug leaks a bit after you install it (which it should not) just dump some Alumi Seal in the old radiator to fix it.
