Now most of the heat sink are made of light and sturdy aluminum material, of which the best thermal conductivity of aluminum alloy, good air-cooled radiator generally made of aluminum. As for copper, there is also a copper radiator on the market. The thermal conductivity of copper is much faster than that of aluminum. However, the copper does not dissipate heat quickly. Copper can quickly remove the heat, but it can not be cooled in a short time To dissipate their own heat, in addition copper oxidizability is the biggest drawback of copper itself. When the oxidation state of copper appears, it will greatly decrease from the aspects of heat conduction and heat dissipation
