C1100

C1100紫(zi)銅用途比純鐵廣泛得多(duo),每(mei)年有50%的銅被(bei)電解(jie)提純為,用于(yu)電氣工(gong)業。

簡(jian)介

因其(qi)顏色(se)為紫紅色(se)而得名。各種性質見銅。就是工業純銅,其(qi)熔(rong)點為1083℃,無(wu)同(tong)素(su)異構轉變(bian),相對密(mi)度為8.9,為鎂的五倍。比普(pu)通鋼還(huan)重(zhong)約15%。其(qi)具有玫(mei)瑰紅色(se),表面形成氧化膜后(hou)呈紫色(se),故(gu)一般(ban)稱為紫銅。它是含有一定(ding)氧的銅,因而又稱含氧銅。

適用范圍


紫銅有良(liang)好的(de)導(dao)(dao)電、導(dao)(dao)熱(re)、耐蝕和加(jia)工(gong)性能,可以焊(han)(han)接和釬焊(han)(han)。含降低導(dao)(dao)電、導(dao)(dao)熱(re)性雜質較(jiao)少,微量的(de)氧對導(dao)(dao)電、導(dao)(dao)熱(re)和加(jia)工(gong)等性能影響不大,但易引起"氫病",不宜在高溫(wen)(如(ru)>370℃)還原性氣氛(fen)中(zhong)加(jia)工(gong)(退火、焊(han)(han)接等)和使用。

這(zhe)里所(suo)說的(de),確實要(yao)非常(chang)純(chun)(chun)(chun)(chun),含銅(tong)(tong)(tong)達99.95%以上才行。極(ji)少(shao)量的(de)雜(za)質(zhi),特別是磷、砷、鋁等(deng),會大大降低銅(tong)(tong)(tong)的(de)導電(dian)(dian)(dian)率。銅(tong)(tong)(tong)中(zhong)含氧(yang)(煉銅(tong)(tong)(tong)時容易(yi)混入少(shao)量氧(yang))對(dui)導電(dian)(dian)(dian)率影響(xiang)很大,用于電(dian)(dian)(dian)氣(qi)工(gong)業的(de)銅(tong)(tong)(tong)一般都必須是。另外(wai),鉛、銻(ti)、等(deng)雜(za)質(zhi)會使銅(tong)(tong)(tong)的(de)結(jie)晶不(bu)能結(jie)合在(zai)一起,造成熱脆,也會影響(xiang)純(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)的(de)加工(gong)。這(zhe)種純(chun)(chun)(chun)(chun)度很高(gao)的(de)純(chun)(chun)(chun)(chun)銅(tong)(tong)(tong),一般用電(dian)(dian)(dian)解(jie)法精制:把不(bu)純(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(即粗銅(tong)(tong)(tong))作陽(yang)極(ji),純(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)作陰(yin)(yin)極(ji),以硫酸銅(tong)(tong)(tong)溶液(ye)為電(dian)(dian)(dian)解(jie)液(ye)。當電(dian)(dian)(dian)流通過(guo)后,陽(yang)極(ji)上不(bu)純(chun)(chun)(chun)(chun)的(de)銅(tong)(tong)(tong)逐(zhu)漸熔解(jie),純(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)便逐(zhu)漸沉淀(dian)在(zai)陰(yin)(yin)極(ji)上。這(zhe)樣精制而得的(de)銅(tong)(tong)(tong);純(chun)(chun)(chun)(chun)度可(ke)達99.99%。
