Is that not because the copper holds more heat, so stays hot for longer at the same dissipation?
Maybe you're right, but I remember than in the 2000s I've had identical cpu heatsinks in both copper/aluminum versions, and the aluminum one had better performance. And then they started to make hybrid ones, stating that the copper part was to allow rapid heat transference and the aluminum parts to improve dissipation. But maybe it was all marketing.
Aluminium is significantly cheaper, that's why they make coolers with a copper base and alu fins. It's a good compromise.
Aluminium is cheaper and lighter.
This seems to suggest that the metal-air transmission is virtually identical between the two, and cites some sources: https://electronics.stackexchange.com/questions/255731/copper-or-aluminum-heatsink
