C11000

C11000紫(zi)銅用(yong)途比純(chun)鐵廣泛得多,每年有50%的銅被電解提(ti)純(chun)為(wei)純銅,用于電氣工業(ye)。

簡介(jie)

因(yin)其(qi)顏色為(wei)紫紅色而得名。各種性質(zhi)見銅(tong)(tong)(tong)。紫銅(tong)(tong)(tong)就是工業純銅(tong)(tong)(tong),其(qi)熔點為(wei)1083℃,無同素異構轉變,相對密度為(wei)8.9,為(wei)鎂的(de)五倍(bei)。比(bi)普通鋼還重約15%。其(qi)具(ju)有玫瑰紅色,表面形成(cheng)氧化膜后呈紫色,故一般(ban)稱為(wei)紫銅(tong)(tong)(tong)。它(ta)是含有一定(ding)氧的(de)銅(tong)(tong)(tong),因(yin)而又稱含氧銅(tong)(tong)(tong)。

適用(yong)范圍(wei)


紫銅(tong)有良好的(de)導電、導熱(re)、耐蝕和加(jia)工性(xing)能,可(ke)以(yi)焊接和釬(han)焊。含(han)降低導電、導熱(re)性(xing)雜質較少,微量的(de)氧對導電、導熱(re)和加(jia)工等(deng)性(xing)能影響不大,但(dan)易(yi)引起"氫病",不宜在高(gao)溫(如(ru)>370℃)還原性(xing)氣氛中加(jia)工(退火、焊接等(deng))和使用。

這里(li)所(suo)說的(de)紫銅(tong)(tong)(tong),確實(shi)要非常純(chun)(chun),含銅(tong)(tong)(tong)達(da)99.95%以(yi)上才(cai)行。極(ji)少(shao)量(liang)的(de)雜質,特(te)別是磷、砷(shen)、鋁(lv)等,會大(da)大(da)降低銅(tong)(tong)(tong)的(de)導電(dian)(dian)率(lv)。銅(tong)(tong)(tong)中(zhong)含氧(煉銅(tong)(tong)(tong)時容易混入少(shao)量(liang)氧)對導電(dian)(dian)率(lv)影響很(hen)大(da),用于電(dian)(dian)氣工業(ye)的(de)銅(tong)(tong)(tong)一般都必須是無氧銅(tong)(tong)(tong)。另外,鉛、銻、鉍(bi)等雜質會使銅(tong)(tong)(tong)的(de)結(jie)晶不(bu)(bu)能結(jie)合在(zai)一起,造(zao)成(cheng)熱脆,也會影響純(chun)(chun)銅(tong)(tong)(tong)的(de)加工。這種(zhong)純(chun)(chun)度很(hen)高的(de)純(chun)(chun)銅(tong)(tong)(tong),一般用電(dian)(dian)解(jie)(jie)法精制(zhi):把不(bu)(bu)純(chun)(chun)銅(tong)(tong)(tong)(即粗銅(tong)(tong)(tong))作陽極(ji),純(chun)(chun)銅(tong)(tong)(tong)作陰極(ji),以(yi)硫酸(suan)銅(tong)(tong)(tong)溶液為電(dian)(dian)解(jie)(jie)液。當電(dian)(dian)流通過后,陽極(ji)上不(bu)(bu)純(chun)(chun)的(de)銅(tong)(tong)(tong)逐漸熔解(jie)(jie),純(chun)(chun)銅(tong)(tong)(tong)便(bian)逐漸沉淀(dian)在(zai)陰極(ji)上。這樣精制(zhi)而得的(de)銅(tong)(tong)(tong);純(chun)(chun)度可達(da)99.99%。
