WebMay 1, 2014 · The values for the electrical and thermal conductivities in pure solid iron are in the range 1.76 – 1.97 × 10 6 Ω − 1 m − 1 and 286–330 W m −1 K −1, respectively, with the … Web7.1.2 Thermal property. Thermal conductivity is the property of a material to conduct heat. Heat transfer occurs at a lower rate across materials of low thermal conductivity than across materials of high thermal conductivity. This property is temperature dependent and its reciprocal is thermal resistivity.
