Copper is a chemical element that is represented by Cu on the elemental table and by the atomic number 29. It is what is referred to as a ductile material, which means that it is easily converted into wire.
For this reason, and because it is both thermally and electrically conductive, copper is often used as an electrical conductor. Most wire used to power electronics is copper. It is also commonly used in piping because of its thermal conductivity. Other uses include building material, electromagnets, integrated circuits, roofing, and flatware. Copper is even used prominently in architecture—copper domes are particularly popular, as are copper statues. The Statue of Liberty is probably the most prominent example of this, literally and figuratively, standing 305 ft. tall and possessing a unique position within American history and lore. Copper is also commonly used in currency, though it is less common now than it once was. The American Nickel is 75% copper, while the Euro currency is often copper plated.
Copper has been used, in its purest form and as an alloy, for thousands of years all over the world. The United States and Chile have some of the world’s largest copper deposits, which are mined mainly through open pit mining methods. Coppers consistent use across centuries means that it will likely continue to be a valuable and useful mineral for the foreseeable future.
