Summary

This article provides thermal conductivity data for a selection of metals and alloys. Thermal conductivity measures a materials ability to allow heat to pass through it via conductance.

Introduction

Thermal conductivity measures a materials ability to allow heat to pass through it via conductance. The thermal conductivity of a material is highly dependent on composition and structure. Generally speaking, dense materials such as metals and stone are good conductors of heat, while low density substances such as gas and porous insulation are poor conductors of heat.

The thermal conductivity of materials is required for the analysis of thermal resistance networks when studying heat transfer in a system.

Please refer to the article "Thermal conductivity values for other common materials" for further information.
