The Comparison of Thermal Conductivity for Different Metals

Abstract

An important part of engineering properties, thermal conductivity consists of internal ability of
material to transfer heat. It is a solid property in metals because of free electrons that help in proper
thermal energy shift. When a material has low thermal conductivity, heat transfer takes place at a
lower rate than a material with high thermal conductivity. For instance, metals can efficiently
conduct heat with high thermal conductivity.
There have been a lot of studies conducted on electric conductivity of various materials, but there
is a lack of research on thermal conductivity of various metals. This study is aimed to fill this gap
by conducting a review of recent studies related to phonon and electron thermal conductivities of
various metals because separating those
components is vital to understand the key mechanisms of heat transfer in applications. It is inferred that phonon thermal conductivity is non-negligible in “transitionintermetallic-compounds (TICs)” and transition metals in comparison to noble metals because of
high velocities of phonon group. In addition, the impact of coupling between phonon and electron
on phonon conductivity in TICs is stronger than the coupling effect of nobles.  metals and in various
