I didn't know that. But brass is an alloy of copper and zinc, so how much better would depend on the alloy composition. From a thermal conductivity POV Copper > Aluminum > Zinc. But heck yes, if a radiator had a substantial portion of total copper it would be able to conduct more heat away from the coolant. But aluminum is very good as far as heat dissipation is concerned. It's also way more plentiful and cheap than copper.
