Aluminium - Thermal Conductivity

Nov 17, 2020  Aluminium – Thermal Conductivity. Thermal conductivity of Aluminium is 237 W/ (mK). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction.

Thermal conductivity - Wikipedia

There are several ways to measure thermal conductivity; each is suitable for a limited range of materials. Broadly speaking, there are two categories of measurement techniques: steady-state and transient.Steady-state techniques infer the thermal conductivity from measurements on the state of a material once a steady-state temperature profile has been reached, whereas transient techniques ...
