2、特(te)點(dian)簡介
純(chun)(chun)銅(tong)是玫瑰紅色金屬，表(biao)面形成氧化銅(tong)膜后呈紫(zi)色，故工業純(chun)(chun)銅(tong)常稱(cheng)紫(zi)銅(tong)或(huo)電解(jie)銅(tong)。火煉可得99－99.9%的純(chun)(chun)銅(tong)，電解(jie)可以(yi)使銅(tong)的純(chun)(chun)度達(da)到99.95-99.99%。 密度為8-9g/cm3，熔點1083°C。純(chun)(chun)銅(tong)導電性(xing)很(hen)好(hao)(hao)，大量(liang)用(yong)于(yu)制(zhi)(zhi)造(zao)電線、電纜、電刷等(deng)；導熱性(xing)好(hao)(hao)，常用(yong)來制(zhi)(zhi)造(zao)須防磁性(xing)干擾的磁學儀器、儀表(biao)，如羅(luo)盤、航空儀表(biao)等(deng)；塑性(xing)極好(hao)(hao)，易(yi)于(yu)熱壓和冷壓力加工，可制(zhi)(zhi)成管、棒、線、條、帶、板、箔(bo)等(deng)銅(tong)材(cai)。純(chun)(chun)銅(tong)產(chan)品有冶煉品及加工品兩種。產(chan)品規格齊(qi)全(quan)，價格優惠，包裝完好(hao)(hao)，銅(tong)質純(chun)(chun)凈，直線度好(hao)(hao)，庫存(cun)量(liang)大，可提供(gong)材(cai)質證(zheng)明和SGS報告 。
紫銅(tong)(tong)是較為純凈的(de)(de)(de)(de)銅(tong)(tong)。它充分(fen)表現(xian)了(le)金(jin)屬(shu)銅(tong)(tong)的(de)(de)(de)(de)延展性(xing)(xing)、導電性(xing)(xing)和耐腐蝕性(xing)(xing)，其中(zhong)延展性(xing)(xing)是銅(tong)(tong)飾的(de)(de)(de)(de)重要特征(zheng)。紫銅(tong)(tong)的(de)(de)(de)(de)熔(rong)點(dian)很高，不易鑄造，而良好的(de)(de)(de)(de)延展性(xing)(xing)彌補了(le)這一缺(que)點(dian)，因此能夠很容易地加工成各種造型(xing)圖案。暗紅的(de)(de)(de)(de)金(jin)屬(shu)光(guang)澤使其在表達現(xian)代感的(de)(de)(de)(de)同時還具有(you)沉(chen)穩(wen)、高貴的(de)(de)(de)(de)品質，是銅(tong)(tong)飾中(zhong)最(zui)常使用的(de)(de)(de)(de)材料。

5、紫(zi)銅(tong)帶的用途
紫(zi)銅(tong)(tong)(tong)的(de)(de)(de)(de)用(yong)途比純(chun)(chun)鐵廣泛得(de)多，每年有50%的(de)(de)(de)(de)銅(tong)(tong)(tong)被電(dian)(dian)解提純(chun)(chun)為(wei)純(chun)(chun)銅(tong)(tong)(tong)，用(yong)于(yu)電(dian)(dian)氣工(gong)業。這(zhe)里所說的(de)(de)(de)(de)紫(zi)銅(tong)(tong)(tong)，確實要非常純(chun)(chun)，含銅(tong)(tong)(tong)達99.95%以上才行(xing)，極(ji)少量的(de)(de)(de)(de)雜質，特別(bie)是(shi)磷、砷、鋁(lv)等(deng)，會大(da)(da)大(da)(da)降低(di)銅(tong)(tong)(tong)的(de)(de)(de)(de)導(dao)電(dian)(dian)率。銅(tong)(tong)(tong)中含氧(煉銅(tong)(tong)(tong)時容易混入(ru)少量氧)對導(dao)電(dian)(dian)率影(ying)響很大(da)(da)，用(yong)于(yu)電(dian)(dian)氣工(gong)業的(de)(de)(de)(de)銅(tong)(tong)(tong)一(yi)般都(dou)必(bi)須(xu)是(shi)無氧銅(tong)(tong)(tong)。另外，鉛、銻、鉍等(deng)雜質會使(shi)銅(tong)(tong)(tong)的(de)(de)(de)(de)結晶不(bu)(bu)能結合在(zai)一(yi)起，造成熱脆，也會影(ying)響純(chun)(chun)銅(tong)(tong)(tong)的(de)(de)(de)(de)加工(gong)。這(zhe)種(zhong)純(chun)(chun)度很高的(de)(de)(de)(de)純(chun)(chun)銅(tong)(tong)(tong)，一(yi)般用(yong)電(dian)(dian)解法精制：把不(bu)(bu)純(chun)(chun)銅(tong)(tong)(tong)(即(ji)粗銅(tong)(tong)(tong))作(zuo)(zuo)陽(yang)極(ji)，純(chun)(chun)銅(tong)(tong)(tong)作(zuo)(zuo)陰極(ji)，以硫酸銅(tong)(tong)(tong)溶液為(wei)電(dian)(dian)解液。當(dang)電(dian)(dian)流通(tong)過(guo)后，陽(yang)極(ji)上不(bu)(bu)純(chun)(chun)的(de)(de)(de)(de)銅(tong)(tong)(tong)逐(zhu)漸熔解，純(chun)(chun)銅(tong)(tong)(tong)便逐(zhu)漸沉淀在(zai)陰極(ji)上。這(zhe)樣精制而得(de)的(de)(de)(de)(de)銅(tong)(tong)(tong);純(chun)(chun)度可達99.99%。 紫(zi)銅(tong)(tong)(tong)是(shi)比較(jiao)(jiao)純(chun)(chun)凈(jing)的(de)(de)(de)(de)一(yi)種(zhong)銅(tong)(tong)(tong)，一(yi)般可近似認為(wei)是(shi)純(chun)(chun)銅(tong)(tong)(tong)，導(dao)電(dian)(dian)性、塑(su)性都(dou)較(jiao)(jiao)好，但強度、硬度較(jiao)(jiao)差一(yi)些(xie)
