It is the metal with the highest electrical conductivity (higher than that of copper) and with the improved thermal conductivity. It occurs naturally in the native state that is combined in compounds such as chlorine, arsenic, sulfur and antimony. The amount of silver available on the Earth's crust is 0.0800 ppm (g/ton), more than 20 times that of gold, which is 0.0040 ppm (g/ton).

As the gold, silver is traded in troy ounces, in the forms of ingots weigh from 450 to 1250-troy ounces, with a minimum purity of 99.9%. Silver is widely used in industry, for which a part is used in the form of granules.

The silver title is the minimum percentage of pure silver present in the alloy that makes up an object. The mark 800 indicates a composition of guaranteed minimum of 800 shares of pure silver and 200 shares of copper and other minerals. The title 835 has been used for many silver coins as for 500 lire with the caravels minted since 1957 by the Italian Mint.
