t2紫(zi)(zi)銅(tong)(tong)棒就是銅(tong)(tong)單質，因(yin)其顏色為(wei)(wei)紫(zi)(zi)紅色而(er)得名。各種性質見(jian)銅(tong)(tong)。紫(zi)(zi)銅(tong)(tong)就是工業純銅(tong)(tong)，其熔點為(wei)(wei)1083℃，無同(tong)素異構轉變，相(xiang)對(dui)密(mi)度為(wei)(wei)8.9，為(wei)(wei)鎂的五倍。比普通(tong)鋼還(huan)重約15%。其具有玫瑰紅色，表面形(xing)成氧(yang)化膜后呈紫(zi)(zi)色，故(gu)一般稱(cheng)為(wei)(wei)紫(zi)(zi)銅(tong)(tong)。它(ta)是含(han)有一定氧(yang)的銅(tong)(tong)，因(yin)而(er)又(you)稱(cheng)含(han)氧(yang)銅(tong)(tong)。
1.t2紫銅板的性質
紫(zi)銅(tong)(tong)(tong)(tong)(tong)因呈紫(zi)紅色而得名。它不一定(ding)是純銅(tong)(tong)(tong)(tong)(tong)，有時還加(jia)入少量脫氧元(yuan)素或其(qi)(qi)他(ta)元(yuan)素,以改善(shan)材質和(he)性能因此也歸(gui)入銅(tong)(tong)(tong)(tong)(tong)合金。中(zhong)國(guo)紫(zi)銅(tong)(tong)(tong)(tong)(tong)加(jia)工(gong)材按成分(fen)(fen)可分(fen)(fen)為：普通紫(zi)銅(tong)(tong)(tong)(tong)(tong)(T1、T2、T3、T4)、無(wu)(wu)氧銅(tong)(tong)(tong)(tong)(tong)（TU1、TU2和(he)高(gao)純、真空無(wu)(wu)氧銅(tong)(tong)(tong)(tong)(tong)）、脫氧銅(tong)(tong)(tong)(tong)(tong)（TUP、TUMn）、添(tian)加(jia)少量合金元(yuan)素的(de)特種(zhong)銅(tong)(tong)(tong)(tong)(tong)（砷銅(tong)(tong)(tong)(tong)(tong)、碲(di)銅(tong)(tong)(tong)(tong)(tong)、銀銅(tong)(tong)(tong)(tong)(tong)）四類。紫(zi)銅(tong)(tong)(tong)(tong)(tong)的(de)電導(dao)(dao)率和(he)熱導(dao)(dao)率僅次于(yu)(yu)銀，廣泛用(yong)于(yu)(yu)制(zhi)(zhi)作導(dao)(dao)電、導(dao)(dao)熱器材。紫(zi)銅(tong)(tong)(tong)(tong)(tong)在大氣、海水和(he)某些非氧化(hua)(hua)性酸(suan)（鹽酸(suan)、稀硫(liu)酸(suan)）、堿、鹽溶液及多種(zhong)有機酸(suan)（醋酸(suan)、檸檬(meng)酸(suan)）中(zhong)，有良好(hao)的(de)耐蝕(shi)性，用(yong)于(yu)(yu)化(hua)(hua)學工(gong)業。另外，紫(zi)銅(tong)(tong)(tong)(tong)(tong)有良好(hao)的(de)焊(han)接性，可經冷、熱塑性加(jia)工(gong)制(zhi)(zhi)成各種(zhong)半(ban)成品和(he)成品。20世紀70年代，紫(zi)銅(tong)(tong)(tong)(tong)(tong)的(de)產量超過了其(qi)(qi)他(ta)各類銅(tong)(tong)(tong)(tong)(tong)合金的(de)總產量。
t2紫銅棒中的微量雜質對銅的導電、導熱性能有嚴重影響。其中鈦、磷、鐵、硅等顯著降低電導率,而鎘、鋅等則影響很小。氧、硫、硒、碲等在銅中的固溶度很小,可與銅生成脆性化合物,對導電性影響不大，但能降低加工塑性。普通紫銅在含氫或一氧化碳的還原性氣氛中加熱時，氫或一氧化碳易與晶界的氧化亞銅(Cu2O)作用，產生高壓水蒸氣或二氧化碳氣體，可使銅破裂。這種現象常稱為銅的“氫病”。 具有優良的導電性﹑導熱性﹑延展性和耐蝕性。主要用于制作發電機﹑母線﹑電纜﹑開關裝置﹑變壓器等電工器材和熱交換器﹑管道﹑太陽能加熱裝置的平板集熱器等導熱器材。常用的銅合金分為黃銅﹑青銅﹑白(bai)銅3大類。
純凈的銅是紫紅色的金屬，俗稱(cheng)“紫(zi)銅”、“紅銅”或“赤銅”。 紫(zi)銅富(fu)有(you)延展性。象一(yi)滴(di)水(shui)那么大小(xiao)的(de)純銅，可拉成長達兩公里的(de)細絲，或壓延成比床(chuang)還大的(de)幾(ji)乎(hu)透明的(de)箔。紫(zi)銅最可貴(gui)的(de)性質是導電性能非(fei)常好，在所有(you)的(de)金屬中僅次于(yu)銀(yin)。但銅比銀(yin)便宜得多(duo)，因(yin)此成了電氣工業的(de)“主(zhu)角”。
2.t2紫銅板的(de)用途
紫銅的用途比純鐵廣泛得多，每年有50%的銅被電解提純為純銅，用于電氣工業。這里所說的紫銅，確實要非常純，含銅達99.95%以上才行。極少量的雜質，特別是磷、砷、鋁等，會大大降低銅的導電率。銅中含氧(煉銅時容易混入少量氧)對導電率影響很大，用于電氣工業的銅一般都必須是無氧銅。另外，鉛、銻、鉍等雜質會(hui)使銅的結晶不能結合(he)在一起(qi)，造成(cheng)熱脆，也會(hui)影響純銅的加工(gong)。
t2紫銅棒是比較(jiao)純凈的一(yi)種銅，一(yi)般(ban)可近似認為是純銅，導電性、塑性都(dou)較(jiao)好，但強(qiang)度、硬度較(jiao)差一(yi)些。
