Copper is one of the most widely used metals found on planet Earth. The shiny, reddish-orange element is believed to be the first metal used by humans thousands of years ago. In modern society, copper plays a vital role in everyday life. Its physical properties, which are similar to gold and silver, make it perfectly suited for a range of industrial uses including electric wiring, plumbing, roofing and industrial machinery.
Copper is soft, pliable and malleable, and it conducts heat and electricity very well. However, unlike gold and silver, copper is not widely viewed as a currency. Therefore, copper costs far less than precious metals. The global supply of copper comes principally from underground mines and from recycling copper products.
