Characteristic

 

Copper is a chemical element with the atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color,elemental substance is purplish red.In cables and electrical and electronic components are the most commonly used materials, but also can be used as building materials, can be composed of many kinds of alloy.Copper alloys have excellent mechanical properties and low resistivity, among which bronze and brass are the most important.Copper is also a durable metal that can be recycled many times without loss of mechanical properties.
