CuNi18Zn19Pb1鋅白銅簡介(jie) 

一、化學(xue)成分 

CuNi18Zn19Pb1鋅白銅的化學(xue)成(cheng)分(fen)如下：

銅（Cu）：59.0 - 63.0%

鎳(nie)（Ni）：17.0 - 19.0%

鋅（Zn）：余量

鉛（Pb）：0.3 - 1.5%

鐵（Fe）：≤0.3%

其(qi)他總(zong)和：≤0.4%

二(er)、所(suo)屬類別及相(xiang)關銅合(he)金

白(bai)(bai)銅(tong)(tong)范(fan)疇：白(bai)(bai)銅(tong)(tong)是以鎳為主要添加元素的(de)銅(tong)(tong)合金，CuNi18Zn19Pb1屬(shu)于(yu)白(bai)(bai)銅(tong)(tong)中的(de)一種(zhong)。工(gong)業用白(bai)(bai)銅(tong)(tong)分(fen)為結構(gou)(gou)白(bai)(bai)銅(tong)(tong)和電(dian)工(gong)白(bai)(bai)銅(tong)(tong)兩大(da)類。結構(gou)(gou)白(bai)(bai)銅(tong)(tong)機械(xie)性能(neng)和耐蝕性好(hao)，色(se)澤美觀(guan)，廣泛(fan)用于(yu)制造精密(mi)機械(xie)、化(hua)工(gong)機械(xie)和船舶構(gou)(gou)件(jian)；電(dian)工(gong)白(bai)(bai)銅(tong)(tong)一般(ban)有良(liang)好(hao)的(de)熱電(dian)性能(neng)。

與其(qi)他銅合金對比(bi)

黃(huang)(huang)(huang)銅(tong)(tong)：以鋅作(zuo)主(zhu)要(yao)添(tian)加元素的(de)銅(tong)(tong)合金，為改善性能常(chang)(chang)添(tian)加其他元素，如(ru)鋁、鎳、錳、錫、硅、鉛等(deng)。與CuNi18Zn19Pb1不同，黃(huang)(huang)(huang)銅(tong)(tong)有著自己(ji)獨特的(de)性能和(he)用途，例如(ru)含鋅30%的(de)黃(huang)(huang)(huang)銅(tong)(tong)常(chang)(chang)用來制作(zuo)彈殼，含鋅40%的(de)黃(huang)(huang)(huang)銅(tong)(tong)常(chang)(chang)用作(zuo)各種零(ling)部件等(deng)。

青(qing)(qing)銅(tong)(tong)(tong)(tong)：原指銅(tong)(tong)(tong)(tong)錫(xi)合(he)金(jin)，后除黃銅(tong)(tong)(tong)(tong)、白銅(tong)(tong)(tong)(tong)以外的銅(tong)(tong)(tong)(tong)合(he)金(jin)均稱青(qing)(qing)銅(tong)(tong)(tong)(tong)，并常在青(qing)(qing)銅(tong)(tong)(tong)(tong)名(ming)字(zi)前(qian)冠(guan)以主要(yao)添(tian)加(jia)元素(su)的名(ming)。青(qing)(qing)銅(tong)(tong)(tong)(tong)有不(bu)同種(zhong)類(lei)，如錫(xi)青(qing)(qing)銅(tong)(tong)(tong)(tong)鑄造性(xing)(xing)能(neng)、減(jian)摩(mo)性(xing)(xing)能(neng)好和機械性(xing)(xing)能(neng)佳，適合(he)制造軸(zhou)承(cheng)、蝸輪、齒輪等；鉛青(qing)(qing)銅(tong)(tong)(tong)(tong)是(shi)現代(dai)發動機和磨床廣泛(fan)使(shi)用的軸(zhou)承(cheng)材料；鋁青(qing)(qing)銅(tong)(tong)(tong)(tong)強(qiang)度高，耐(nai)磨性(xing)(xing)和耐(nai)蝕性(xing)(xing)好，用于鑄造高載荷的齒輪、軸(zhou)套、船用螺旋槳(jiang)等。

三、性能特(te)點

機(ji)械(xie)性(xing)(xing)能：具有較好的(de)機(ji)械(xie)性(xing)(xing)能，能滿足制造(zao)精密機(ji)械(xie)等(deng)的(de)要求，不過具體(ti)數值如硬度（HRB）、軟(ruan)化溫度（℃）等(deng)受多種(zhong)因素影響，如加(jia)工狀態(tai)等(deng)。

耐(nai)蝕(shi)(shi)(shi)性(xing)：結構白(bai)銅本身機械性(xing)能和耐(nai)蝕(shi)(shi)(shi)性(xing)好(hao)，CuNi18Zn19Pb1作(zuo)為其中一(yi)種(zhong)白(bai)銅，在耐(nai)蝕(shi)(shi)(shi)性(xing)方面也有不錯的(de)(de)表現，適用(yong)于(yu)一(yi)些(xie)需要耐(nai)腐蝕(shi)(shi)(shi)的(de)(de)環境，例如化工機械構件等。

色澤美觀：可(ke)用于(yu)一(yi)些對外觀有(you)要求的部(bu)件(jian)制造，像(xiang)眼鏡配件(jian)等(deng)精密機械部(bu)件(jian)。

四、應用領域(yu)

精密(mi)機(ji)(ji)械制(zhi)造：可用于制(zhi)造各種精密(mi)機(ji)(ji)械部件，如精密(mi)儀器中的零件等。
