Copper metal, a chemical element with the symbol Cu and atomic number 29

Most copper is used in electrical equipment such as wiring and motors. This is because it conducts both heat and electricity very well, and can be drawn into wires. It also has uses in construction (for example roofing and plumbing), and industrial machinery (such as heat exchangers).

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and 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 colour.

  • Symbol: "Cu": from Latin cuprum
  • Electrical resistivity: 16.78 nΩ⋅m (at 20 °C)
  • Naming: after Cyprus, principal mining place in ...
  • Thermal expansion: 16.5 µm/(m⋅K) (at 25 °C)

Today copper, because it is such a good conductor of electricity, is used in electrical generators and motors for electrical wiring and in electronic goods, such as radios and TVs. Copper also conducts heat well, so it is used in motor vehicle radiators, air-conditioners and home heating systems.

It helps your body make red blood cells and keeps nerve cells and your immune system healthy. It also helps form collagen, a key part of bones and connective tissue. Copper may also act as an antioxidant, reducing free radicals that can damage cells and DNA. Copper helps the body absorb iron.
