kobbermetall

Kobbermetall is the Norwegian word for copper metal. Copper is a chemical element with the symbol Cu 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 reddish-orange color. Copper is known since prehistoric times and has been used by humans for thousands of years.

Copper is widely used in electrical wiring, plumbing, roofing, and cookware due to its excellent conductivity and corrosion resistance. It is also a key component in many alloys, such as brass and bronze, which have diverse applications in industry and art. In its elemental form, copper is a reddish-brown metal.

The discovery and use of copper marked a significant step in human technological development, leading to the Chalcolithic or Copper Age. Its ability to be easily shaped and its durability made it ideal for tools, weapons, and decorative objects. Historically, copper was also important in coinage.

Economically, copper is one of the most important industrial metals. Its price is closely watched as an indicator of global economic health. Major producers of copper include Chile, Peru, China, and the United States. Recycling of copper is also a significant part of the global copper supply.
