Copper

Copper

Copper is a reddish orange coloured chemical element. Cooper is one for the few metals that are readily usable in its natural form. It is also one of the few metals that have a colour other than grey and silver. Extraction of copper is mostly done as copper sulphides from open pit mines and porphyry copper deposits.

Copper is a good conductor of electricity and is used in many applications like power generation, power transmission, telecommunication, electrical circuits, power distribution and other electrical equipment, as well. Copper has a combination of properties, which include thermal conductivity, tensile strength, ductility, corrosion resistance, low thermal expansion, malleability and ease of installation. Integrated circuits are making more use of copper due to its superior electrical conductivity. Copper is also used in architecture, building constructions and interior designing. Architectural elements include domes, spires, vaults, flashings, roofs and building expansion joints also. Its ability to form into complex shapes and corrosion resistance makes it usable in many architectures. Other uses include electromagnets, cathode tubes, vacuum tubes, cathode tubes and magnetrons. The electrical conductivity of copper also enhances the efficiency of electrical motors.
