Copper metal and alloys

By admin ~ May 19th, 2010. Filed under: Copper.

Copper metal and alloys have been used for thousands of years. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as Cyprium, “metal of Cyprus”, later shortened to Cuprum. There may be insufficient reserves to sustain current high rates of copper consumption.[1] Some countries, such as Chile and the United States, still have sizable reserves of the metal which are extracted through large open pit mines.

It’s a fair cop

A copper is a term for a Police man or woman. This word first appeared in the early 18th century, and can be matched with the word “cap”, which has the same meaning and whose etymology can be traced to the Latin word ‘capere’. It is also believed that the term Copper was popularly believed to represent the copper badges American officers used to wear at the time of origin, but in fact probably used in Britain to mean “someone who cops” long before this. “cop” is a slang word for punishment. Hence “a fair cop” and “cop for that”.

The Copper Age

The Copper Age is a phase in the development of human culture in which the use of early metal tools appeared alongside the use of stone tools.

The period is a transitional one outside of the traditional three-age system, and occurs between the Neolithic and Bronze Age. It appears that copper was not widely exploited at first and that efforts in alloying it with tin and other metals began quite soon, making distinguishing the distinct Chalcolithic cultures and later periods difficult. The boundary between the Copper and Bronze Ages is indistinct, since alloys sputtered in and out of use due to the erratic supply of tin.
