ENGLISH > MATERIALS

Metals are chemical elements consisting of crystalline solids characterized by good electrical and thermal conductivity. They are for the most part endowed with high values of the specific weight, as well as of reflecting power, ductility and malleability. A small number of metals exists naturally in the elementary state (such as copper, gold, silver and platinum), while the others, being widespread in the form of minerals in the state of oxides and sulfides, require the use of various methods of extractive metallurgy for their preparation in the pure state.
