I'm no radiator expert, but I play one on TV, and my understanding is that
brass/copper radiators are as much two times more efficient than aluminum
radiators.
The benefit of an aluminum radiator is that it's less expensive, about
two-thirds lighter, less expensive, more corrosion resistant with modern
coolant, less expensive, and lasts longer. Oh, and did I mention that
aluminum radiators are less expensive? Of course, that's the real reason
brass/copper radiators aren't manufactured any longer. I believe some
radiators even have plastic tanks bonded to an aluminum core.
