The heat sink material refers to the specific material used for the heat sink. Each material its thermal conductivity is different, according to the thermal conductivity from high to low, respectively, silver, copper, aluminum, steel. However, if silver is used as a heat sink, it will be too expensive, so the better solution is to use copper. Although aluminum is much cheaper, it is obviously not as good as copper in terms of thermal conductivity (only about 50% points of copper).
At present, the commonly used heat sink material is copper and aluminum alloy, both have their own advantages and disadvantages. Copper has good thermal conductivity, but it is more expensive, difficult to process, heavy (many pure copper radiators exceed the weight limit of the CPU), small heat capacity, and easy to oxidize. Pure aluminum is too soft to be used directly. The aluminum alloy used can provide sufficient hardness. The advantages of aluminum alloy are low price and light weight, but the thermal conductivity is much worse than copper. Some radiators take their own advantages and embed a copper plate on the base of the aluminum alloy radiator.
For ordinary users, aluminum fins are sufficient to meet the heat dissipation requirements.

North winter heating radiator is also called heat sink.
The heat sink plays an important role in the composition of the radiator. In addition to the active heat dissipation of the fan, the evaluation of the quality of a radiator depends largely on the heat absorption capacity and heat conduction capacity of the heat sink itself.
