What is the difference between copper and aluminum radiators?

Question

Cooling systems

The cost of aluminum is 3 times lower than that of the same size made of copper (I look at Ali).
The question is, is it worth it or can you not fool around and take it cheaper?

Answer 1

Copper is almost twice as good a conductor of heat as aluminum.

And in general, she is almost the top on this list, only silver is better.
