1. Copper
Humans havebeen using copper since the predynastic Egyptians and Sumerians.During the Roman Empire copper was principally mined on Cyprus,hence the origin of the name of the metal as Cyprium (metal ofCyprus), later shortened to Cuprum.
As technologyhas progressed copper has remained a highly useful element.Although the Copper Development Association reports that 0.7trillion pounds of copper have been mined throughout history, thereare still over five trillion pounds remaining in the earth.According to the May 26, 2007 edition of New Scientist, the earthhas an estimated 61 years supply of copper left. Fortunatelyhowever, copper has an infinite recyclable life and has one of thehighest recycling rates of any other engineering metal. The factthat premium grade scrap has about 95 percent of the value of newlymined metal ensures that this rate remains high. The wire industryuses primarily newly refined copper for its products.
Second only tosilver in its electrical conductivity, this reddish, lustrous metalis highly ductile and malleable. Surpassing both gold and aluminumin its electrical conductivity, copper is now being used forbonding wire. When alloyed with nickel and/or manganese, it findsuse in resistance wire applications.
Copper and itsalloys have excellent ductility and are supplied by California FineWire in ribbon and round forms. Round diameters can be drawn assmall as 0.0005 and ribbons rolled as small as 0.00025” x 0.010”.Call us to discover our capabilities on your specific wireneeds.
Copper wire can be readily plated with such materials as gold,nickel, silver, tin, or solder. We process a wide range of copperwire. From high silicon bronze to brass; from copper with cadmium tocopper with zirconium, California Fine Wire has a wire to suit yourneeds. Whether your application requires the strength and corrosionresistance of berrilyium modified copper or the purity of 99.999%copper.
