General speaking, each material of heat sink has different thermal conductivity. According to heat-conducting property from high to lower, it should be silver, copper, aluminum, steel. Silver has better thermal conductivity, but it is expensive. Therefore, the best solution is copper. Although aluminum is cheap, its thermal conductivity is not as good as copper.

At present, the commonly used heat sink materials are copper and aluminum alloy inrapid prototyping, both of which have their advantages and disadvantages. Copper has good thermal conductivity, but it is more expensive, more difficult to process, overweight, less heat capacity, and easily oxidized. Pure aluminum is too soft to be used directly, and aluminum alloy can provide sufficient hardness. The advantages of aluminum alloy are low price and light weight, but the thermal conductivity is much worse than copper.

A heat sink is a device that dissipates electronic components in electrical appliances. It is mostly made of aluminum alloy, brass or bronze in plate shape, sheet shape, multi-sheet shape, etc… For example, the CPU central processor in the computer needs to use a relatively large heat sink, and the power tube, line tube in the TV, and the power amplifier tube in the power amplifier must use heat sinks.

The heat sink plays an important role in the composition of the heat sink, in addition to the active cooling of the fan, assessing the quality of a radiator depends largely on the heat sinking capacity and heat conduction capacity of the heat sink itself.
