Brief History of Copper
Copper was the first metal that humans mined and crafted over 10,000 years ago. Copper was so plentiful that it could be mined at surface level. One of the main reasons for it being used so early is it is relatively easy to shape. However, it was somewhat too soft for many tools. People learned around 5000 years ago that copper could become stronger if it was mixed with other metals. As examples, brass is a mixture of copper and zinc while bronze is a mixture of copper and tin.
The Roman Empire obtained most of its copper from the island of Cyprus, which is where copper's name originated. Copper is the Latin word cuprum, which means "from the island of Cyprus". Copper is one of the basic chemical elements with the symbol Cu and atomic number 29. In its pure state copper has a reddish-orange color and is one of only two metals that are colored. The other colored metal is gold, which is yellowish in color. Copper's melting point is 1,985 degrees Fahrenheit.
It's likely the first alloy ever made by humans was bronze. After the Stone Age came the Bronze Age and then the Iron Age. During the Bronze Age, both bronze and copper were used for making tools and weapons.
Copper conducts heat well and resists corrosion and is used worldwide in pipes and tubing to distribute both hot and cold fluids through homes and buildings. Pure copper (greater than 99.95%) is called electrolytic copper (EC). Copper is a great conductor of electricity and even small amounts of impurities in copper can seriously reduce its ability to conduct electricity. Copper is also a major player in various other applications such as cables, computers, coins, radiators, energy etc...Over 40% of manufactured copper is used in the electrical and electronics industry followed by construction, transportation, industrial machinery and general consumer.
In the United States, the first copper mine opened in Granby, Connecticut in 1705. The first copper rolling mill in the U.S. was established by a prominent silversmith named Paul Revere in Canton, Massachusetts, in 1801.
