High-Purity sample sheets of open-celled aluminium foam. The material is highly porous (this sample has a porosity value of 93%) and this type of material is typically an essential component of heat exchangers such as cooling systems for advanced technology electronic equipment and cryogen tanks. The high strength  which can be achieved with very light weights in metal foams (this sample has a bulk density of only 0.2 grammes per cubic centimetre) is ideal for technologies such as advanced aerospace components. The photographs were taken at Goodfellow Cambridge Ltd, UK,  who supply the material for research purposes.
