FOAMED-METAL COMPONENTS FOR WIRELESS-COMMUNICATION TOWERS.

摘要

A wireless-communications-tower component being at least partially formed from a foamed metal. The foamed metal has a density of less than 2.7 g/cm3, a thermal conductivity greater than 1 W/m⋠K, and a coefficient of thermal expansion of less than 30 μm/m⋠K. Such a foamed metal can be an open-cell foamed metal or a closed-cell foamed metal. Foamed metal components can also present a non-foamed or polymer-coated surface.
