黃銅排和紫銅排是兩種不同銅的存在形態。它們在人們的日常生活中和工業生產中均得到了廣泛的應用，對于我國銅產業的發展，具有非常重要的意義。

　　黃(huang)銅(tong)(tong)(tong)排(pai)是由銅(tong)(tong)(tong)和(he)鋅所組(zu)成的合金(jin)。如(ru)果只是由銅(tong)(tong)(tong)、鋅組(zu)成的黃(huang)銅(tong)(tong)(tong)排(pai)就叫作(zuo)普(pu)通(tong)(tong)黃(huang)銅(tong)(tong)(tong)排(pai)。黃(huang)銅(tong)(tong)(tong)排(pai)常被用于制造閥門、水管、空調內外機連接管和(he)散熱器等。黃(huang)銅(tong)(tong)(tong)排(pai)以(yi)鋅作(zuo)主要添(tian)加元(yuan)(yuan)(yuan)素的銅(tong)(tong)(tong)合金(jin)﹐具有美觀(guan)的黃(huang)色﹐統稱(cheng)黃(huang)銅(tong)(tong)(tong)排(pai)。銅(tong)(tong)(tong)鋅二元(yuan)(yuan)(yuan)合金(jin)稱(cheng)普(pu)通(tong)(tong)黃(huang)銅(tong)(tong)(tong)排(pai)或稱(cheng)簡單黃(huang)銅(tong)(tong)(tong)排(pai)。三元(yuan)(yuan)(yuan)以(yi)上(shang)的黃(huang)銅(tong)(tong)(tong)排(pai)稱(cheng)特殊(shu)黃(huang)銅(tong)(tong)(tong)排(pai)或稱(cheng)復雜(za)黃(huang)銅(tong)(tong)(tong)排(pai)。

　　紫銅(tong)就是銅(tong)單質，因(yin)其(qi)顏色(se)為紫紅(hong)色(se)而得(de)名(ming)。各(ge)種(zhong)性質見銅(tong)。就是工業(ye)純(chun)銅(tong)，其(qi)熔點為1083℃，無同素異構轉變，相對密度為8.9，為鎂的(de)五倍。比普通鋼還重約15%。其(qi)具(ju)有玫瑰紅(hong)色(se)，表面形(xing)成(cheng)氧化(hua)膜后呈紫色(se)，故一般(ban)稱(cheng)為紫銅(tong)排。它是含有一定氧的(de)銅(tong)，因(yin)而又稱(cheng)含氧銅(tong)。

　　黃銅(tong)排與(yu)紫銅(tong)排的(de)主(zhu)要(yao)的(de)區別是密度(du)和用途(tu)不同：

　　黃(huang)銅排(pai)(pai)的密度(du)(為8.93g/cm3)多用與機(ji)(ji)械軸瓦內襯，耐磨(mo)。黃(huang)銅排(pai)(pai)鑄(zhu)件(jian)常用來制作閥門和管(guan)(guan)(guan)道配(pei)件(jian)等。普通黃(huang)銅排(pai)(pai)的用途(tu)極為廣泛，如(ru)水(shui)箱帶、供(gong)排(pai)(pai)水(shui)管(guan)(guan)(guan)、獎章(zhang)、波紋管(guan)(guan)(guan)、蛇形管(guan)(guan)(guan)、冷凝管(guan)(guan)(guan)、彈殼及(ji)各種形狀復雜(za)的沖制品、小五金件(jian)等。隨著鋅含量的增(zeng)加(jia)從H63到H59，它們均能很好地(di)承受熱態加(jia)工，多用于(yu)機(ji)(ji)械及(ji)電器(qi)的各種零件(jian)、沖壓件(jian)及(ji)樂器(qi)等處。

　　純(chun)銅又稱紫銅，密度(du)(為7.83g/cm3}，熔點為1083度(du)，無磁性(xing)(xing)(xing)。有(you)良(liang)好的(de)(de)(de)導(dao)電，導(dao)熱性(xing)(xing)(xing)能(neng)及抗蝕，有(you)韌性(xing)(xing)(xing)。紫銅富有(you)延(yan)展性(xing)(xing)(xing)。象一滴水那(nei)么大小的(de)(de)(de)純(chun)銅，可(ke)拉成(cheng)長(chang)達(da)兩公里的(de)(de)(de)細絲，或壓延(yan)成(cheng)比(bi)床還大的(de)(de)(de)幾乎透明的(de)(de)(de)箔。紫銅排***可(ke)貴(gui)的(de)(de)(de)性(xing)(xing)(xing)質是(shi)導(dao)電性(xing)(xing)(xing)能(neng)非常好，在所有(you)的(de)(de)(de)金屬(shu)中僅次于銀。但銅比(bi)銀便宜得多，因此成(cheng)了電氣工業的(de)(de)(de)“主角”。

　　所以(yi)黃銅(tong)(tong)排好還是(shi)洛陽紫銅(tong)(tong)排好的(de)(de)回答是(shi):黃銅(tong)(tong)排與紫銅(tong)(tong)排各有千秋，被用(yong)于(yu)在不同的(de)(de)領域，在它(ta)們之間并(bing)沒有孰優(you)孰劣之說。
