2. 早在埃及前王朝時期與蘇美爾文明，人類就已經(jīng)開始使用銅。羅馬帝國時期，銅的主要開采地為塞浦路斯島，這種金屬因此得名Cyprium（塞浦路斯之金屬），后縮寫為 Cuprum（銅的拉丁詞源）。

3. 隨著技術(shù)發(fā)展，銅始終是極具實(shí)用價值的元素。銅發(fā)展協(xié)會的數(shù)據(jù)顯示，歷史上累計(jì)開采銅達(dá) 0.7 萬億磅，但地殼中仍留存超過 5萬億磅銅資源。據(jù) 2007 年 5 月 26 日《新科學(xué)家》雜志報(bào)道，地球上現(xiàn)存銅儲量預(yù)計(jì)還可開采 61年。不過幸運(yùn)的是，銅可無限循環(huán)再生，在各類工程金屬中擁有極高的回收率。優(yōu)質(zhì)銅廢料價值約為原生礦銅的95%，這保障了銅的高回收率。線材行業(yè)生產(chǎn)產(chǎn)品主要采用新精煉銅。

4. 這種紅亮金屬的導(dǎo)電性能僅次于銀，延展性與可塑性。銅的導(dǎo)電能力優(yōu)于金和鋁，現(xiàn)已被用于制作鍵合線。銅與鎳、錳（單一或復(fù)合）制成合金后，可用于電阻絲。

5. 銅及其合金延展性優(yōu)異，加州精細(xì)線材可提供銅帶與圓線產(chǎn)品。圓線拉制小直徑可達(dá) 0.0005 英寸，銅帶軋制小規(guī)格為 0.00025 英寸×0.010 英寸。歡迎聯(lián)系我們，了解針對您特定線材需求的加工能力。

6. 銅線表面可輕松電鍍金、鎳、銀、錫或焊料等鍍層。我們可加工多種類型銅線：高硅青銅、黃銅、鎘銅、鋯銅等，加州精細(xì)線材均可提供適配您需求的線材。無論您的應(yīng)用場景需要鈹改性銅帶來的高強(qiáng)度與耐腐蝕性，還是純度99.999% 的高純銅。

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.
