The thermal conductivity of a material is a measure of its ability to conduct heat. It is commonly denoted by k, λ, or κ and, in SI units, is measured in W·m−1·K−1. It quantifies the proportionality b
Exhaust system components with ceramic coatings having a low thermal conductivity reduce heating of nearby sensitive components.

A metal is a material that, when polished or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. These properties are all associated with having electrons availa
Thermal conductivity and resistivity
…conductivity transfer heat more efficiently than those with low thermal conductivity. Heat transport can arise from different microscopic mechanisms: In metals, thermal conductivity is typically dominated by free electrons, whereas in dielectric materials such as diamond it is largely due to lattice vibrations…
