2、特點(dian)簡介(jie)
純(chun)銅是玫瑰紅色金屬(shu)，表(biao)面形成氧化銅膜(mo)后(hou)呈紫(zi)色，故工業純(chun)銅常稱紫(zi)銅或電(dian)(dian)(dian)解銅。火煉可(ke)得99－99.9%的純(chun)銅，電(dian)(dian)(dian)解可(ke)以使銅的純(chun)度(du)(du)達到(dao)99.95-99.99%。 密度(du)(du)為8-9g/cm3，熔點1083°C。純(chun)銅導電(dian)(dian)(dian)性(xing)很(hen)好，大量用于制造電(dian)(dian)(dian)線(xian)、電(dian)(dian)(dian)纜、電(dian)(dian)(dian)刷等；導熱性(xing)好，常用來(lai)制造須(xu)防磁性(xing)干擾的磁學儀器(qi)、儀表(biao)，如(ru)羅(luo)盤(pan)、航(hang)空儀表(biao)等；塑(su)性(xing)極好，易于熱壓和冷壓力加(jia)工，可(ke)制成管、棒、線(xian)、條、帶、板、箔等銅材。純(chun)銅產品有冶煉品及加(jia)工品兩(liang)種(zhong)。產品規格(ge)齊全，價格(ge)優惠，包裝完(wan)好，銅質(zhi)純(chun)凈，直線(xian)度(du)(du)好，庫存量大，可(ke)提供材質(zhi)證明和SGS報告 。
紫銅(tong)是較為純凈(jing)的(de)(de)銅(tong)。它充分表現了(le)金屬(shu)銅(tong)的(de)(de)延展性(xing)(xing)、導電性(xing)(xing)和耐腐蝕(shi)性(xing)(xing)，其(qi)中(zhong)延展性(xing)(xing)是銅(tong)飾的(de)(de)重要特征。紫銅(tong)的(de)(de)熔(rong)點(dian)很(hen)(hen)高，不易鑄(zhu)造，而良(liang)好的(de)(de)延展性(xing)(xing)彌補了(le)這(zhe)一缺(que)點(dian)，因此能夠很(hen)(hen)容(rong)易地加工(gong)成各種造型圖案。暗紅的(de)(de)金屬(shu)光澤使其(qi)在表達現代感的(de)(de)同(tong)時還具有沉穩(wen)、高貴的(de)(de)品質，是銅(tong)飾中(zhong)最常使用的(de)(de)材料。

5、紫(zi)銅帶(dai)的用途
紫銅(tong)(tong)(tong)(tong)的(de)用途比(bi)純(chun)鐵廣泛得(de)多，每年有50%的(de)銅(tong)(tong)(tong)(tong)被電(dian)解提(ti)純(chun)為(wei)純(chun)銅(tong)(tong)(tong)(tong)，用于(yu)電(dian)氣工業(ye)。這(zhe)(zhe)里所(suo)說的(de)紫銅(tong)(tong)(tong)(tong)，確實要非(fei)常純(chun)，含銅(tong)(tong)(tong)(tong)達(da)(da)99.95%以(yi)上(shang)才行，極(ji)(ji)(ji)少量的(de)雜質(zhi)，特別是(shi)(shi)(shi)磷、砷、鋁等(deng)，會大(da)大(da)降低銅(tong)(tong)(tong)(tong)的(de)導(dao)電(dian)率(lv)。銅(tong)(tong)(tong)(tong)中(zhong)含氧(yang)(煉(lian)銅(tong)(tong)(tong)(tong)時容易混入少量氧(yang))對導(dao)電(dian)率(lv)影響(xiang)很大(da)，用于(yu)電(dian)氣工業(ye)的(de)銅(tong)(tong)(tong)(tong)一(yi)(yi)般(ban)都必(bi)須是(shi)(shi)(shi)無氧(yang)銅(tong)(tong)(tong)(tong)。另外，鉛、銻、鉍等(deng)雜質(zhi)會使銅(tong)(tong)(tong)(tong)的(de)結(jie)晶不(bu)(bu)能結(jie)合在(zai)一(yi)(yi)起，造成(cheng)熱(re)脆，也會影響(xiang)純(chun)銅(tong)(tong)(tong)(tong)的(de)加工。這(zhe)(zhe)種純(chun)度很高(gao)的(de)純(chun)銅(tong)(tong)(tong)(tong)，一(yi)(yi)般(ban)用電(dian)解法精制：把不(bu)(bu)純(chun)銅(tong)(tong)(tong)(tong)(即粗銅(tong)(tong)(tong)(tong))作(zuo)陽極(ji)(ji)(ji)，純(chun)銅(tong)(tong)(tong)(tong)作(zuo)陰(yin)極(ji)(ji)(ji)，以(yi)硫(liu)酸銅(tong)(tong)(tong)(tong)溶(rong)液為(wei)電(dian)解液。當電(dian)流通(tong)過(guo)后(hou)，陽極(ji)(ji)(ji)上(shang)不(bu)(bu)純(chun)的(de)銅(tong)(tong)(tong)(tong)逐漸熔(rong)解，純(chun)銅(tong)(tong)(tong)(tong)便逐漸沉淀在(zai)陰(yin)極(ji)(ji)(ji)上(shang)。這(zhe)(zhe)樣精制而得(de)的(de)銅(tong)(tong)(tong)(tong);純(chun)度可達(da)(da)99.99%。 紫銅(tong)(tong)(tong)(tong)是(shi)(shi)(shi)比(bi)較(jiao)純(chun)凈的(de)一(yi)(yi)種銅(tong)(tong)(tong)(tong)，一(yi)(yi)般(ban)可近似(si)認為(wei)是(shi)(shi)(shi)純(chun)銅(tong)(tong)(tong)(tong)，導(dao)電(dian)性(xing)、塑(su)性(xing)都較(jiao)好，但強度、硬(ying)度較(jiao)差(cha)一(yi)(yi)些
