This is from a thread on the FOT from 1/30/2007, "Aluminum Radiators.
"According to Ron Davis Radiators, the heat transfer coefficient for
brass radiators is 100.6 and for aluminum is 111 making aluminum +10%
more efficient. Aluminum has a density of 2.70 grams/cubic cm, brass is
8.4 grams/cubic cm and copper is 8.96 grams/cubic cm. For comparison,
stainless steel is 7.9 grams/cubic cm.

You might also contact Scott at Wizard Cooling. They built our "replica"
aluminum radiator for our 1961 TR4 vintage racer. As I recall, he had quite
a bit of information on aluminum versus copper.
