Copper/brass have better coefficients for heat transfer, but tube & fin design/layout in a modern radiator can make up for decreased heat transfer of aluminum (compared to an 'old' radiator).



Soooooo, that most likely makes now, 2 advantages that the newer styled aluminum rad. has over a "stock" unit.

I'm still not convinced that a longer tube has less efficiency over shorter, but numerically more, tubes.
