產品描述：
銅（Cuprum）是(shi)一種(zhong)金(jin)屬(shu)元素，也是(shi)一種(zhong)過渡(du)元素，化(hua)學符(fu)號Cu，英文copper，原(yuan)子序數29。黃(huang)銅是(shi)銅鋅合(he)金(jin)，由銅和鋅組成(cheng)的(de)(de)黃(huang)銅稱為普通黃(huang)銅。純銅是(shi)柔軟的(de)(de)金(jin)屬(shu)，表面剛切開時為紅(hong)橙色帶金(jin)屬(shu)光澤，單(dan)質呈紫紅(hong)色。延展性(xing)(xing)好(hao)，導(dao)熱性(xing)(xing)和導(dao)電性(xing)(xing)高，因此在電纜和電氣(qi)、電子元件是(shi)常用(yong)的(de)(de)材料(liao)，也可用(yong)作建(jian)筑(zhu)材料(liao)，可以組成(cheng)眾多種(zhong)合(he)金(jin)。銅合(he)金(jin)機械(xie)性(xing)(xing)能優異，電阻(zu)率很低(di)，其中重要的(de)(de)數青銅和黃(huang)銅。此外，銅也是(shi)耐用(yong)的(de)(de)金(jin)屬(shu)，可以多次回收(shou)而無損其機械(xie)性(xing)(xing)能。

產品介紹：
黃銅(tong)是銅(tong)鋅合金，由銅(tong)和(he)鋅組成(cheng)的黃銅(tong)稱為(wei)普通黃銅(tong)。它具有高(gao)強度、高(gao)硬(ying)度和(he)很(hen)強的耐(nai)化(hua)學性。切削的機(ji)械性能(neng)也很(hen)突出(chu)。黃銅(tong)具有很(hen)強的耐(nai)磨(mo)性，常被(bei)用于(yu)制造閥門、水管、空調內外(wai)機(ji)連接管和(he)散熱器等。由黃銅(tong)拉制而成(cheng)的無縫銅(tong)管質地柔軟，耐(nai)磨(mo)性強。
紫銅(tong)(tong)(tong)(tong)就是(shi)(shi)銅(tong)(tong)(tong)(tong)單質(zhi)，因其顏色(se)為(wei)(wei)紫紅色(se)而得名。紫銅(tong)(tong)(tong)(tong)是(shi)(shi)工(gong)業(ye)純(chun)銅(tong)(tong)(tong)(tong)，其熔點(dian)為(wei)(wei)1083℃，無同素異構(gou)轉變，相對密度為(wei)(wei)8.9，為(wei)(wei)鎂的(de)(de)五倍。同體積的(de)(de)質(zhi)量比(bi)普(pu)通鋼重約(yue)15%。因其具有(you)玫(mei)瑰紅色(se)，表面形成(cheng)氧(yang)化(hua)膜(mo)后呈紫色(se)，故一(yi)般稱(cheng)為(wei)(wei)紫銅(tong)(tong)(tong)(tong)。它(ta)是(shi)(shi)含有(you)一(yi)定氧(yang)的(de)(de)銅(tong)(tong)(tong)(tong)，因而又(you)稱(cheng)含氧(yang)銅(tong)(tong)(tong)(tong)。紫銅(tong)(tong)(tong)(tong)的(de)(de)用(yong)途比(bi)純(chun)鐵廣泛(fan)得多(duo)，每年有(you)50%的(de)(de)銅(tong)(tong)(tong)(tong)被電解提純(chun)為(wei)(wei)純(chun)銅(tong)(tong)(tong)(tong)，用(yong)于電氣工(gong)業(ye)。
