用途

紫(zi)銅(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)(de)用(yong)(yong)途(tu)比純(chun)鐵廣泛得多,每年有50%的(de)(de)(de)(de)銅(tong)(tong)(tong)(tong)(tong)(tong)被電(dian)(dian)解提(ti)純(chun)為,用(yong)(yong)于電(dian)(dian)氣(qi)工(gong)業。這(zhe)里(li)所(suo)說的(de)(de)(de)(de)紫(zi)銅(tong)(tong)(tong)(tong)(tong)(tong),確實(shi)要(yao)(yao)非常純(chun),含(han)銅(tong)(tong)(tong)(tong)(tong)(tong)達99.95%以上(shang)才行,極(ji)(ji)少(shao)量的(de)(de)(de)(de)雜質,特(te)別是(shi)磷(lin)、砷、鋁等(deng)(deng),會大(da)大(da)降低銅(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)(de)導(dao)(dao)電(dian)(dian)率(lv)。主要(yao)(yao)用(yong)(yong)于制(zhi)作(zuo)發電(dian)(dian)機﹑母線﹑電(dian)(dian)纜﹑開關(guan)裝(zhuang)置(zhi)﹑變(bian)壓(ya)器(qi)(qi)等(deng)(deng)電(dian)(dian)工(gong)器(qi)(qi)材和熱(re)交換(huan)器(qi)(qi)﹑管道﹑太陽(yang)能(neng)加(jia)熱(re)裝(zhuang)置(zhi)的(de)(de)(de)(de)等(deng)(deng)導(dao)(dao)熱(re)器(qi)(qi)材。銅(tong)(tong)(tong)(tong)(tong)(tong)中含(han)氧(煉銅(tong)(tong)(tong)(tong)(tong)(tong)時容(rong)易混入少(shao)量氧)對導(dao)(dao)電(dian)(dian)率(lv)影(ying)(ying)響很(hen)大(da),用(yong)(yong)于電(dian)(dian)氣(qi)工(gong)業的(de)(de)(de)(de)銅(tong)(tong)(tong)(tong)(tong)(tong)一般都必須(xu)是(shi)無氧銅(tong)(tong)(tong)(tong)(tong)(tong)。另(ling)外,鉛、銻、鉍等(deng)(deng)雜質會使銅(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)(de)結(jie)晶不(bu)能(neng)結(jie)合(he)在一起(qi),造成熱(re)脆,也會影(ying)(ying)響純(chun)銅(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)(de)加(jia)工(gong)。這(zhe)種(zhong)很(hen)高的(de)(de)(de)(de)純(chun)銅(tong)(tong)(tong)(tong)(tong)(tong),一般用(yong)(yong)精制(zhi):把不(bu)純(chun)銅(tong)(tong)(tong)(tong)(tong)(tong)(即粗銅(tong)(tong)(tong)(tong)(tong)(tong))作(zuo)陽(yang)極(ji)(ji),純(chun)銅(tong)(tong)(tong)(tong)(tong)(tong)作(zuo)陰(yin)極(ji)(ji),以硫酸銅(tong)(tong)(tong)(tong)(tong)(tong)溶液(ye)為電(dian)(dian)解液(ye)。當(dang)電(dian)(dian)流(liu)通過后,陽(yang)極(ji)(ji)上(shang)不(bu)純(chun)的(de)(de)(de)(de)銅(tong)(tong)(tong)(tong)(tong)(tong)逐(zhu)漸熔(rong)解,純(chun)銅(tong)(tong)(tong)(tong)(tong)(tong)便(bian)逐(zhu)漸沉(chen)淀在陰(yin)極(ji)(ji)上(shang)。這(zhe)樣(yang)精制(zhi)而得的(de)(de)(de)(de)銅(tong)(tong)(tong)(tong)(tong)(tong);純(chun)度可達99.99%。

紫銅還用于電(dian)機短路(lu)環,電(dian)磁加熱感應器的制作,和大功(gong)率電(dian)子元(yuan)件上面,接線排(pai)接線端子之類的。

紫銅也(ye)運(yun)用到了門、窗、扶(fu)手等(deng)家(jia)具及裝飾上。
