C11000因其顏色(se)(se)為(wei)紫(zi)(zi)紅(hong)色(se)(se)而(er)得(de)名(ming)。各種性(xing)質(zhi)見銅(tong)(tong)。紫(zi)(zi)銅(tong)(tong)就是工業純銅(tong)(tong)，其熔點(dian)為(wei)1083℃，無同素異構(gou)轉變，相對(dui)密度為(wei)8.9，為(wei)鎂(mei)的五倍(bei)。比普通(tong)鋼還重(zhong)約15%。其具有(you)(you)玫(mei)瑰紅(hong)色(se)(se)，表面(mian)形成氧化膜后呈紫(zi)(zi)色(se)(se)，故一(yi)般稱為(wei)紫(zi)(zi)銅(tong)(tong)。它是含(han)(han)有(you)(you)一(yi)些氧的銅(tong)(tong)，因而(er)又稱含(han)(han)氧銅(tong)(tong)。C11000有(you)(you)良好的導電(dian)、導熱(re)(re)(re)、耐蝕和(he)(he)加工性(xing)能,可以焊(han)接和(he)(he)釬焊(han)。含(han)(han)降低導電(dian)、導熱(re)(re)(re)性(xing)雜質(zhi)較少,微量的氧對(dui)導電(dian)、導熱(re)(re)(re)和(he)(he)加工等(deng)性(xing)能影響不大，但易引(yin)起“氫病”，不宜(yi)在高溫（如>370℃）還原(yuan)性(xing)氣氛(fen)中加工（退火、焊(han)接等(deng)）和(he)(he)使(shi)用。

這里(li)所說的(de)(de)(de)紫銅(tong)(tong)(tong)，確實要(yao)非(fei)常純(chun)(chun)，含(han)銅(tong)(tong)(tong)達99.95%以上才行。極少量的(de)(de)(de)雜(za)質(zhi)，特別是(shi)磷、砷、鋁(lv)等，會(hui)大(da)大(da)降(jiang)低銅(tong)(tong)(tong)的(de)(de)(de)導電(dian)(dian)率。銅(tong)(tong)(tong)中含(han)氧(煉銅(tong)(tong)(tong)時容易混入少量氧)對導電(dian)(dian)率影響很(hen)(hen)大(da)，用于(yu)電(dian)(dian)氣(qi)工業的(de)(de)(de)銅(tong)(tong)(tong)一(yi)般都是(shi)無氧銅(tong)(tong)(tong)。另外(wai)，鉛、銻、鉍等雜(za)質(zhi)會(hui)使銅(tong)(tong)(tong)的(de)(de)(de)結晶不能結合在(zai)一(yi)起，造成熱脆(cui)，也會(hui)影響純(chun)(chun)銅(tong)(tong)(tong)的(de)(de)(de)加(jia)工。這種純(chun)(chun)度(du)很(hen)(hen)高的(de)(de)(de)純(chun)(chun)銅(tong)(tong)(tong)，一(yi)般用電(dian)(dian)解(jie)法精制：把不純(chun)(chun)銅(tong)(tong)(tong)(即粗銅(tong)(tong)(tong))作(zuo)陽極，純(chun)(chun)銅(tong)(tong)(tong)作(zuo)陰極，以硫(liu)酸(suan)銅(tong)(tong)(tong)溶液為電(dian)(dian)解(jie)液。當(dang)電(dian)(dian)流通過后，陽極上不純(chun)(chun)的(de)(de)(de)銅(tong)(tong)(tong)逐(zhu)漸(jian)熔(rong)解(jie)，純(chun)(chun)銅(tong)(tong)(tong)便(bian)逐(zhu)漸(jian)沉淀(dian)在(zai)陰極上。這樣精制而得的(de)(de)(de)銅(tong)(tong)(tong);純(chun)(chun)度(du)可達99

C11000在含氫的的還原介質中(zhong)易產生氫脆，俗稱氫病，故不宜在高溫370攝氏度以(yi)上溫度還原介質中(zhong)進行加工和使(shi)用：在低-250攝氏度以(yi)下，其(qi)強度會提高。

C11000是陰極(ji)重熔銅，其具有高的導電、導熱性，良好的耐(nai)腐(fu)蝕(shi)性和加工(gong)性能，可以熔焊及釬焊。

C11000主(zhu)要用作導電(dian)、導熱和耐(nai)腐蝕元器件，如電(dian)線電(dian)纜、導電(dian)螺(luo)絲(si)、殼體和各種導管(guan)及航空工業(ye)。
