[Aluminium Heat Sink] Universal Aluminium Heat Sink Heat sinks are generally made of metals; and, aluminium is the most common metal used in the heat sink. We are aware of the fact that the thermal conductivity of each metal is different. The thermal conductivity of metal is proportional to the heat transfer in the heat sink. Thus, if the thermal conductivity of the metal increases, then the heat transferring capacity of the heat sink will also increase. The thermal conductivity of aluminium is 235 W/mK, it is the cheapest and most lightweight metal. Aluminium heat sinks are also called extruded heat sinks as they can be made using extrusion.
