產品描述：
銅(tong)(tong)（Cuprum）是(shi)(shi)一種金(jin)屬元(yuan)素(su)，也是(shi)(shi)一種過(guo)渡(du)元(yuan)素(su)，化(hua)學符(fu)號Cu，英文copper，原子(zi)序(xu)數29。黃銅(tong)(tong)是(shi)(shi)銅(tong)(tong)鋅(xin)合金(jin)，由銅(tong)(tong)和鋅(xin)組成的(de)(de)黃銅(tong)(tong)稱為普通黃銅(tong)(tong)。純銅(tong)(tong)是(shi)(shi)柔軟的(de)(de)金(jin)屬，表(biao)面剛切開時為紅橙色(se)帶金(jin)屬光澤，單質呈紫紅色(se)。延(yan)展(zhan)性好，導熱性和導電性高，因此在(zai)電纜(lan)和電氣、電子(zi)元(yuan)件是(shi)(shi)常用的(de)(de)材料，也可用作(zuo)建(jian)筑材料，可以(yi)組成眾(zhong)多種合金(jin)。銅(tong)(tong)合金(jin)機械性能(neng)優(you)異，電阻(zu)率很低，其(qi)中(zhong)重要(yao)的(de)(de)數青銅(tong)(tong)和黃銅(tong)(tong)。此外，銅(tong)(tong)也是(shi)(shi)耐用的(de)(de)金(jin)屬，可以(yi)多次回收而無(wu)損其(qi)機械性能(neng)。

產品介紹：
黃(huang)銅(tong)(tong)(tong)是銅(tong)(tong)(tong)鋅(xin)合(he)金，由銅(tong)(tong)(tong)和鋅(xin)組(zu)成的(de)黃(huang)銅(tong)(tong)(tong)稱為普通(tong)黃(huang)銅(tong)(tong)(tong)。它具(ju)有(you)(you)高(gao)(gao)強度、高(gao)(gao)硬度和很(hen)強的(de)耐(nai)化學性。切(qie)削的(de)機械性能也很(hen)突出。黃(huang)銅(tong)(tong)(tong)具(ju)有(you)(you)很(hen)強的(de)耐(nai)磨性，常被用于制造閥門、水管、空(kong)調內外機連接管和散(san)熱器(qi)等(deng)。由黃(huang)銅(tong)(tong)(tong)拉制而成的(de)無縫銅(tong)(tong)(tong)管質地柔軟，耐(nai)磨性強。
紫(zi)(zi)銅(tong)就(jiu)是銅(tong)單質，因(yin)其顏(yan)色(se)為紫(zi)(zi)紅色(se)而(er)得(de)名。紫(zi)(zi)銅(tong)是工業純(chun)銅(tong)，其熔(rong)點為1083℃，無(wu)同素異構轉變，相對密(mi)度為8.9，為鎂的五倍(bei)。同體(ti)積的質量比(bi)普(pu)通鋼重約15%。因(yin)其具(ju)有玫瑰(gui)紅色(se)，表(biao)面(mian)形成氧化膜后呈紫(zi)(zi)色(se)，故一(yi)般稱為紫(zi)(zi)銅(tong)。它是含有一(yi)定(ding)氧的銅(tong)，因(yin)而(er)又稱含氧銅(tong)。紫(zi)(zi)銅(tong)的用途(tu)比(bi)純(chun)鐵(tie)廣泛得(de)多，每年有50%的銅(tong)被電(dian)解提純(chun)為純(chun)銅(tong)，用于電(dian)氣工業。
