ECU-58

ECU-58紫銅用途比純鐵廣泛得(de)多,每年(nian)有(you)50%的銅被電解提純為純銅,用于電氣工(gong)業。

簡介

因(yin)其顏色為(wei)(wei)紫(zi)紅色而得名(ming)。各種性質見銅(tong)。紫(zi)銅(tong)就是(shi)工業純(chun)銅(tong),其熔(rong)點為(wei)(wei)1083℃,無同素異構轉變(bian),相(xiang)對密度(du)為(wei)(wei)8.9,為(wei)(wei)鎂的五(wu)倍(bei)。比普通鋼還重約15%。其具有玫瑰紅色,表面形成(cheng)氧化膜后呈(cheng)紫(zi)色,故一(yi)般(ban)稱(cheng)為(wei)(wei)紫(zi)銅(tong)。它是(shi)含有一(yi)定氧的銅(tong),因(yin)而又稱(cheng)含氧銅(tong)。

適用范(fan)圍(wei)


紫銅有良好的導(dao)電(dian)、導(dao)熱、耐蝕和(he)(he)加工(gong)性能,可以(yi)焊(han)接(jie)和(he)(he)釬焊(han)。含降(jiang)低導(dao)電(dian)、導(dao)熱性雜質較少,微量的氧(yang)對(dui)導(dao)電(dian)、導(dao)熱和(he)(he)加工(gong)等性能影(ying)響不(bu)大,但易引起"氫病",不(bu)宜在高溫(wen)(如>370℃)還原(yuan)性氣氛中加工(gong)(退火、焊(han)接(jie)等)和(he)(he)使用。

這里所說的(de)(de)(de)(de)紫(zi)銅(tong)(tong),確實要非常純(chun)(chun),含(han)銅(tong)(tong)達99.95%以上才行。極(ji)(ji)少量(liang)的(de)(de)(de)(de)雜質(zhi),特(te)別(bie)是磷、砷(shen)、鋁等(deng)(deng),會大(da)大(da)降(jiang)低銅(tong)(tong)的(de)(de)(de)(de)導電(dian)率(lv)。銅(tong)(tong)中含(han)氧(yang)(煉銅(tong)(tong)時容(rong)易混入(ru)少量(liang)氧(yang))對導電(dian)率(lv)影(ying)響(xiang)很(hen)大(da),用于電(dian)氣(qi)工業的(de)(de)(de)(de)銅(tong)(tong)一般(ban)都必(bi)須是無氧(yang)銅(tong)(tong)。另外,鉛、銻、鉍等(deng)(deng)雜質(zhi)會使銅(tong)(tong)的(de)(de)(de)(de)結(jie)晶不能結(jie)合在一起(qi),造成熱(re)脆,也會影(ying)響(xiang)純(chun)(chun)銅(tong)(tong)的(de)(de)(de)(de)加(jia)工。這種純(chun)(chun)度(du)很(hen)高(gao)的(de)(de)(de)(de)純(chun)(chun)銅(tong)(tong),一般(ban)用電(dian)解法(fa)精制:把不純(chun)(chun)銅(tong)(tong)(即粗銅(tong)(tong))作陽(yang)極(ji)(ji),純(chun)(chun)銅(tong)(tong)作陰極(ji)(ji),以硫酸銅(tong)(tong)溶(rong)液為電(dian)解液。當電(dian)流通過(guo)后,陽(yang)極(ji)(ji)上不純(chun)(chun)的(de)(de)(de)(de)銅(tong)(tong)逐(zhu)漸熔解,純(chun)(chun)銅(tong)(tong)便逐(zhu)漸沉(chen)淀在陰極(ji)(ji)上。這樣(yang)精制而得的(de)(de)(de)(de)銅(tong)(tong);純(chun)(chun)度(du)可達99.99%。
