Recently, a client from North America talked with me about the material of radiator, copper and aluminum.
In general, the aluminum radiator is more efficient than that made of copper in heat dissipation. From the aspect of material, aluminum has good heat dissipation, while copper does well in thermal conductivity. A good radiator, not only depends on it material selection, but also the overall designing and manufacturing process.
Radiating area and fan air volume as well as industrial design are important index that affect the performance of radiator.
As far as the actual situation is concerned, aluminum has an advantage over copper in price, and the improvement of fabrication process of aluminum radiator, the demand of aluminum radiator is far greater than that of copper radiator. （message from Leo）
