Aluminum is often selected for its electrical conductivity, which is nearly twice that of copper on an equivalent weight basis. The requirements of high conductivity and mechanical strength can be met by use of long-line, high-voltage, aluminum steel-cored reinforced transmis-sion cable. The thermal conductivity of aluminum alloys, about 50 to 60%

ALUMINUM Galvanized steel is steel coated with zinc during a zinc solution heat batch. This process protects the steel from corrosion and cracks and, like aluminum, has a good strength-to-weight ratio. Galvanized steel has a lower cost per pound than aluminum but may have some issues in adhesion of paints depending on end use.
