Copper is quite possibly the metal that mankind has used for longest: copper objects have been found dating as far back as 8700 BC. The Italian name comes from the spoken Latin
(attested in 950 BC
) for the late aeramen
, a derivative of the Latin word aes
which means "copper" or "bronze", names found in other languages of Indo-European origin.
Only later was it replaced (according to Pliny
) by the word cuprum
, from which derives the chemical symbol of the element. In Roman times, most copper was mined on the island of Cyprus
, a fact testified by the expression aes Cyprium
, "copper or bronze from Cyprus".
Copper is a pinkish or reddish metal
of very high electric
and thermal conductivity
, surpassed only by those of silver
; it is highly resistant to corrosion
(due to an adherent coating that forms spontaneously on the surface, first brown and then green or blue-green in colour) and is non-magnetic. It is easy to work and extremely ductile
, but is not suitable for machining with chip removal, because it has a rather pasty consistency; it is easy to recycle and scrap copper has a high recovery value; it can be combined with other metals
to form many metal alloys
(it is estimated that there are at least 400), the most common of which are bronze
, respectively with tin
; among others, there are also cupronickels
(also called aluminium bronzes). It can be used for electric motors, brass faucets and bronze bells.
We use it for our production of tubes, rods and laminates for the telephone, telecommunications, home appliances and automotive sectors.
