What are the custom heat sink materials? what's the effect?

The custom heat sink material refers to the specific material used for the heat sink. The thermal conductivity of each material is different. They are arranged from high to low in terms of thermal conductivity. They are silver, copper, aluminum, and steel. However, if silver is used as the 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 thermal conductivity (only about 50% of copper).

At present, the commonly used heat sink materials are copper and aluminum alloy, both of which have their own advantages and disadvantages. The copper heat sink has good thermal conductivity, but the price is more expensive, the processing is difficult, the weight is too large (many pure copper heat sinks exceed the weight limit of the CPU), the heat capacity is small, and it is easy to oxidize. Pure aluminum is too soft to be used directly. The aluminum alloy used can provide sufficient hardness. Aluminum alloy has the advantages of low price and light weight, but its thermal conductivity is much worse than copper. Some radiators take their own strengths and embed a copper plate on the base of the aluminum alloy radiator.

For ordinary users, the aluminum heat sink is sufficient to meet the heat dissipation requirements.

The radiator for heating in winter in the north is also called a heat sink.

Custom heat sink occupies an important role in the composition of the radiator. In addition to the active heat dissipation of the fan, evaluating the quality of a radiator depends largely on the heat absorption capacity and heat conduction capacity of the heat sink itself.
