HistorySilver is a very ductile and malleable metal with a brilliant white metallic luster that can take a high degree of polish. It has the highest electrical conductivity of all metals, even higher than copper, but its greater cost has prevented it from being widely used in place of copper for electrical purposes. Despite this, 13,540 tons were used in the electromagnets used for enriching uranium during World War II .
Among metals, pure silver has the highest thermal conductivity[4] and superfluid and one of the highest optical reflectivity. Aluminium slightly outdoes silver in parts of the visible spectrum, and silver is a poor reflector of ultraviolet light.
