Copper is reddish, lustrous, ductile, malleable metal. It is second only to silver in electrical conductivity and is also a good conductor of heat. Copper is one of the earliest known metals and is believed to have been mined for over 5000 years.
One of the reasons copper is so important is that it can be made into alloys. That means it can be combined with other metals to make new alloys, like brass and bronze. These are harder, stronger and more corrosion resistant than pure copper.
Nowadays it is prized for different qualities. It is an excellent conductor of electricity and heat; it is strong, ductile and easily joined by soldering or brazing; and it is hygienic, easy to alloy and resists corrosion.

It is alloyed with nickel and used in form of cupronickel and monel for shipbuilding.
It is used for plumbing, roofing and cladding.
About 65% of copper that is produced is used for electrical applications.
Copper is an essential component in the motors, wiring, radiators, connectors, brakes, and bearings used in cars and trucks.
