In this example copper wire has been chosen for the conductor or core of the cable because copper has the property of very good electrical conductivity. Typically, it involves the addition of relatively small amounts of secondary elements to a primary element. Hardness: it is the ability of metal to resist hard objects pressing into its surface. A metal (from Greek mtallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Copper is a very common substance that occurs naturally in the environment and spreads through the environment through natural phenomena. Seamless Copper Tube, Bright Annealed. Pure metals show only small changes in thermal conductivity with temperature. For humans, the requirement is quite low as well, merely 2mg of copper a day for adults.
