This paper presents a literature review of the experimental data and different authors' proposed equations related to the measurement and modelling of the electrical conductivity of metal foams. The analysis is based on the classification scheme that considers two different foam categories: open-cell and closed-cell foams. A new empirical equation is presented to describe the relationship between porosity and electrical conductivity in foamed materials. The aim of this equation is to encompass the different behaviours previously described for different types of foams in a single equation.
