In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and there is no critical temperature at which this crystal structure changes.Consequently, it is ductile and possesses a high level of electrical and thermal conductivity, making it attractive for a wide range of ornamental and practical

List of copper alloys Wikipedia

Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion.The best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. Both of these are imprecise terms, having both been commonly referred to as lattens in the past. Today the term copper alloy tends to be substituted, especially

When copper (and its alloys) and aluminum are exposed to air, they react to form a layer of corrosion that protects the metal from further corrosion. The layer of rust formed when iron reacts with air, on the other hand, is crumbly, and therfore freshlayers of the iron are constantly being exposed to the air.

Mixing lead into the copper-tin alloy produces "lead bronze," which may contain as much as 10% lead. The lead in the alloy does not become part of its crystalline structure, increasing the fluidity of compound when it is in its molten state. This facilitates casting, particularly the casting of finely detailed artistic objects. However lead
