Calculation of Emissivity for Metals
Calculation of Emissivity for Metals

At any given temperature, real materials emit less energy than that of a black body. The effectiveness of a material at emitting energy is represented by a radiative property called emissivity, which is the ratio of the actual energy emitted by the material to that of a black body at the same temperature. This article will provide an overview of the methods available for calculating the spectral, spectral-directional, hemispherical and total hemispherical emissivity for metals.


Thermal Conductivity of Metals and Alloys

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.
