Copper
Copper is one of the most popular and widely-used metals on our planet. The first metal used by humans thousands of years ago, copper is relatively inexpensive in comparison with precious metals.
This shiny, reddish-orange element plays a vital role in our everyday life. It is extremely important for numerous industries, including the production of generators, motors, wiring, heating and cooling machinery, plumbing and roofing.
Copper is pliable, malleable and soft. It is a good heat and electricity conductor. However, unlike its precious peers, silver and gold, copper is not commonly viewed as a currency.
