用(yong)途
紫銅(tong)(tong)的(de)用(yong)途比純(chun)鐵廣(guang)泛得多，每年有(you)50%的(de)銅(tong)(tong)被電(dian)(dian)(dian)解(jie)(jie)提(ti)純(chun)為，用(yong)于(yu)電(dian)(dian)(dian)氣工(gong)業。這(zhe)(zhe)里(li)所說的(de)紫銅(tong)(tong)，確(que)實要非常純(chun)，含(han)銅(tong)(tong)達99.95%以上(shang)才行(xing)，極(ji)(ji)(ji)少量的(de)雜(za)(za)質(zhi)，特別(bie)是(shi)磷、砷、鋁等，會大大降低銅(tong)(tong)的(de)導電(dian)(dian)(dian)率。主要用(yong)于(yu)制作發電(dian)(dian)(dian)機﹑母(mu)線﹑電(dian)(dian)(dian)纜﹑開關裝(zhuang)置﹑變壓器等電(dian)(dian)(dian)工(gong)器材(cai)和熱(re)(re)交換器﹑管道(dao)﹑太陽(yang)能加熱(re)(re)裝(zhuang)置的(de)等導熱(re)(re)器材(cai)。銅(tong)(tong)中含(han)氧(煉銅(tong)(tong)時容易混入少量氧)對導電(dian)(dian)(dian)率影響很(hen)大，用(yong)于(yu)電(dian)(dian)(dian)氣工(gong)業的(de)銅(tong)(tong)一般(ban)都必須是(shi)無氧銅(tong)(tong)。另外，鉛、銻、鉍等雜(za)(za)質(zhi)會使(shi)銅(tong)(tong)的(de)結(jie)(jie)晶不(bu)能結(jie)(jie)合在一起，造成熱(re)(re)脆，也會影響純(chun)銅(tong)(tong)的(de)加工(gong)。這(zhe)(zhe)種很(hen)高的(de)純(chun)銅(tong)(tong)，一般(ban)用(yong)精制:把不(bu)純(chun)銅(tong)(tong)(即粗銅(tong)(tong))作陽(yang)極(ji)(ji)(ji)，純(chun)銅(tong)(tong)作陰極(ji)(ji)(ji)，以硫酸(suan)銅(tong)(tong)溶液為電(dian)(dian)(dian)解(jie)(jie)液。當電(dian)(dian)(dian)流通過后，陽(yang)極(ji)(ji)(ji)上(shang)不(bu)純(chun)的(de)銅(tong)(tong)逐漸(jian)熔解(jie)(jie)，純(chun)銅(tong)(tong)便逐漸(jian)沉淀在陰極(ji)(ji)(ji)上(shang)。這(zhe)(zhe)樣精制而得的(de)銅(tong)(tong);純(chun)度可達99.99%。
紫銅還用于(yu)電(dian)機短路環，電(dian)磁(ci)加(jia)熱感(gan)應器(qi)的(de)制(zhi)作，和大功率電(dian)子元件上面，接線排接線端子之類(lei)的(de)。
紫銅也運(yun)用(yong)到了門、窗、扶(fu)手等家具(ju)及裝飾上。
