The Future With Copper

How do we secure the future with copper?

Copper was probably the first metal used by ancient cultures, and the oldest artefacts made with it date to the Neolithic period. The shiny red-brown metal was used for jewellery, tools, sculpture, bells, vessels, lamps, amulets, and death masks, amongst other things. So important was the metal in human development that it gave its name to the Copper Age, today better known as the Chalcolithic. Copper was necessary to make brass and, of course, bronze, the metal which gave its name to the time period succeeding the Copper Age, besides many other alloys. From Phoenicia to Mesoamerica, copper was a badge of elite status before becoming more widely available. A handy form of exchange in the trade between cultures, eventually, copper symbolic goods were replaced by more manageable ingots which, in turn, evolved into even more convenient coins. Gold and silver may have been common enough for the rich and powerful, but if there was one pure metal that ordinary people in the ancient world could get their hands on, it was copper.
Availability & Mining
Copper was easily found in its metallic state in many areas of the ancient world, albeit in relatively small quantities. The shiny red, orange or brown metal was first used in the Balkans, Middle East, and Near East from 8000 to 3000 BCE. Egypt and Europe later followed suit and began to make their own copper artefacts. Soft and malleable, it was an ideal material to manufacture decorative luxury goods.

What Properties Make Copper Useful?
The excellent alloying properties of copper have made it invaluable when combined with other metals, such as zinc (to form brass), tin (to form bronze), or nickel. These alloys have desirable characteristics and, depending on their composition, are developed for highly specialized applications. For example, copper-nickel alloy is applied to the hulls of ships because it does not corrode in seawater and reduces the adhesion of marine life, such as barnacles, thereby reducing drag and increasing fuel efficiency. Brass is more malleable and has better acoustic properties than pure copper or zinc; consequently, it is used in a variety of musical instruments, including trumpets, trombones, bells, and cymbals.
