In heat transfer, the thermal conductivity of a substance, k, is an intensive property that indicates its ability to conduct heat.
This list makes up the data for the smaller list provided in Thermal conductivity.
Please note that mixtures may have variable thermal conductivities due to its composition.
| Material | Thermal conductivity [W·m−1·K−1] | Temperature [K] | Electrical conductivity @ 293 K [Ω−1·m−1] |
