What is the thermal conductivity of copper?

Copper is an excellent conductor of both heat and electricity, only bettered by silver in both instances. This property can be related to its atomic structure, where the individual copper atoms are packed closely together, allowing electrons to pass between adjacent atoms with relative ease. It is this movement of electrons that infers its excellent conductivity.

Thermal Conductivity of Copper

The thermal conductivity, known as it’s K value, is a measure of how readily temperature will flow through a particular material. It is measured in units of W/m/k. The value for pure copper is 401, for pure silver 406, for nickel 91 and for stainless steels around 16. For Hiduron 130, the thermal conductivity is 46, and for Hidurel 5 it is 190.
