用(yong)途(tu)

紫銅(tong)(tong)(tong)的(de)(de)(de)用(yong)(yong)(yong)途比純(chun)鐵廣泛得多,每年有50%的(de)(de)(de)銅(tong)(tong)(tong)被電(dian)(dian)解提純(chun)為,用(yong)(yong)(yong)于(yu)電(dian)(dian)氣(qi)工(gong)(gong)業(ye)。這里所說的(de)(de)(de)紫銅(tong)(tong)(tong),確實(shi)要非常純(chun),含銅(tong)(tong)(tong)達99.95%以上(shang)才(cai)行,極(ji)少量的(de)(de)(de)雜(za)(za)質(zhi),特別是磷、砷、鋁等(deng),會大大降(jiang)低(di)銅(tong)(tong)(tong)的(de)(de)(de)導(dao)電(dian)(dian)率(lv)。主要用(yong)(yong)(yong)于(yu)制作(zuo)發電(dian)(dian)機﹑母(mu)線﹑電(dian)(dian)纜﹑開關(guan)裝置﹑變壓器(qi)等(deng)電(dian)(dian)工(gong)(gong)器(qi)材(cai)和熱(re)交換(huan)器(qi)﹑管道﹑太(tai)陽能(neng)加熱(re)裝置的(de)(de)(de)等(deng)導(dao)熱(re)器(qi)材(cai)。銅(tong)(tong)(tong)中含氧(yang)(yang)(煉銅(tong)(tong)(tong)時容易混入少量氧(yang)(yang))對導(dao)電(dian)(dian)率(lv)影響(xiang)(xiang)很(hen)大,用(yong)(yong)(yong)于(yu)電(dian)(dian)氣(qi)工(gong)(gong)業(ye)的(de)(de)(de)銅(tong)(tong)(tong)一般(ban)(ban)都必(bi)須是無氧(yang)(yang)銅(tong)(tong)(tong)。另外,鉛、銻、鉍(bi)等(deng)雜(za)(za)質(zhi)會使銅(tong)(tong)(tong)的(de)(de)(de)結(jie)晶不能(neng)結(jie)合在(zai)一起(qi),造成熱(re)脆,也會影響(xiang)(xiang)純(chun)銅(tong)(tong)(tong)的(de)(de)(de)加工(gong)(gong)。這種(zhong)很(hen)高的(de)(de)(de)純(chun)銅(tong)(tong)(tong),一般(ban)(ban)用(yong)(yong)(yong)精(jing)制:把不純(chun)銅(tong)(tong)(tong)(即粗(cu)銅(tong)(tong)(tong))作(zuo)陽極(ji),純(chun)銅(tong)(tong)(tong)作(zuo)陰極(ji),以硫酸銅(tong)(tong)(tong)溶液為電(dian)(dian)解液。當電(dian)(dian)流通過后,陽極(ji)上(shang)不純(chun)的(de)(de)(de)銅(tong)(tong)(tong)逐漸熔(rong)解,純(chun)銅(tong)(tong)(tong)便逐漸沉淀在(zai)陰極(ji)上(shang)。這樣精(jing)制而得的(de)(de)(de)銅(tong)(tong)(tong);純(chun)度可達99.99%。

紫(zi)銅還用于(yu)電機(ji)短路環,電磁加熱感應器的制作(zuo),和大(da)功率電子(zi)元(yuan)件上面,接(jie)線排接(jie)線端子(zi)之類的。

紫銅也運用到了門、窗、扶(fu)手等(deng)家具及裝(zhuang)飾上。
