Silver is a precious metal which is often used in jewellery making and in industrial applications ranging from mobile phones, batteries and pharmaceuticals. It has the highest electrical conductivity of all metals; however, its bigger price has prevented it from being as widely used as copper. One exception to this is in radio-frequency engineering, where silver plating is used to improve the electrical conductivity of the parts. During WWII 13,540 tons were used in the electromagnets used for enriching uranium, because of the wartime shortage of copper. Its price is derived from its availability on the open market so world production numbers are an important statistic to consider.
More recently production has levelled off, which could influence prices in the future. Trading it and predicting the price is a balancing act between what consumers want and what the currency market demands are. Many nations also use silver as the basic unit of monetary value.Trade SI
