Did a bit of checking,this will help with your radiator Doug.

Bosch Automotive handbook.
Compact high performance radiators have cores which consist of alternating corrugated fins and flat tubes.the heat transfere of this design is so high that some passanger car radiators comprise only of 1 row of tubes and have an install depth of only 20mm.

What I took as the alloy radiator making the difference is not the case it looks like it comes down to the fin design.
If you could get copper painted black in this fin design I would say it would be extreamly efficiant

some other figures I found.

emissivity

black body radiator =1
alluminium unmachined=.07
alluminium polished=.04
brass matt=.22
brass polished=.05
copper oxidized=.64
copper polished.05

Copper does a good job.
