27 Facts You Might Not Know about Copper

Copper is an essential mineral found in plant life and in the human body and it is also a metal alloy with a reddish-orange color. The use of copper dates back over 10,000 years. Pure copper is very soft and malleable and is combined with other metals, such as brass and bronze, for use in jewelry and other uses. Copper is used in currency (the U.S. penny), and is used as a heat conductor, in medical instruments, and has been used as a decorative coating of famous gates, such as the Temple of Jerusalem, sculptures, and statues, most notably, The Statue of Liberty, the largest copper statue in the world.

Since 100% of copper can be recycled without any loss of its original mined quality, it is the third most recycled metal. Over 80% of the copper mined since it was discovered thousands of years ago is still in use today. When copper tarnishes, a beautiful green patina covers the piece.

Copper, according to archeological discoveries, was the first metal used by Neolithic mankind to supplement his stone tools over 10,000 years ago.

Copper's antibacterial properties were used in ancient Egypt to sterilize water and prevent infections.

By 600 BC, copper also saw its first use as a medium of monetary exchange.

Most copper occurs in ores and must be smelted for purity before it can be used. But natural chemical reactions do sometimes release native copper, according to Chemicool; this explains why humans have been making things from the metal for at least 8,000 years. People figured out how to smelt copper by about 4500 B.C., further increasing supplies. The next technological leap was creating copper alloys; by adding tin to copper, people made a harder metal: bronze. The technological development (which occurred at different times in different regions) ushered in the Bronze Age.

Copper artifacts are sprinkled throughout the historical record. A tiny awl, the oldest metal object ever found in the Middle East, was discovered buried with a middle-age woman in an ancient village in Israel. The copper probably came from the Caucasus region more than 620 miles (1,000 kilometers) away. In ancient Egypt, people used copper alloys to make jewelry, including toe rings. Researchers have found massive copper mines from the 10th century B.C. in Israel.

In its elemental form, copper is soft, shiny and highly malleable. Due to its soft nature, it is most often used as an alloy. An alloy is a material comprised of a metal and a non-metal or two metals. Alloys are typically stronger than single metal materials. Two common copper alloys are bronze and brass. Bronze is a mixture of copper and tin, while brass is a mixture of copper and zinc and most popularly used in instruments, including brass instruments. Copper is also an excellent conductor of electricity, which is why it is often used in electrical wiring.

Copper is known as a coinage metal. But why is it so popular in coins? Copper is resistant to corrosion from air and water. According to the the United States Mint, the penny was made from copper or a copper alloy up until 1982. Since then, pennies have been made from 97.5% zinc and plated with copper due to its high cost.
