It is one of the non-ferrous metals. It occurs in nature in the form of compounds in pure form. The pure metal melts at ~ 1.083 ° C. It is a good electrical conductor and is suitable as a heat exchanger. According to archaeologists copper is the first of the metals used by man for making utensils, tools and weapons. It is estimated that copper was known about 9,000 BC, possibly because it responds as a native and requires no metallurgical process for the preparation of pure form. Around 3,000 BC the use of copper was completely widespread in the Near East. The use of brass was more widespread in the 2nd millennium until 1 where there was a wider use of iron. The English name of copper resulting from the Latin Cuprum, a word which in turn comes from the island of Cyprus [1], where it was mined during the Roman era.
