Thermal Conductivity of Metals

Thermal conductivity of some common metals

Thermal Conductivity - k - is the quantity of heat transmitted due to an unit temperature gradient, in unit time under steady conditions in a direction normal to a surface of the unit area. Thermal Conductivity - k - is used in the Fourier's equation.
