C1100
C1100簡介
，因(yin)其顏色(se)(se)為紫(zi)紅(hong)色(se)(se)而得名。各種(zhong)性質見銅(tong)(tong)。紫(zi)銅(tong)(tong)就是工業純銅(tong)(tong)，其熔(rong)點為1083℃，無同素異構轉變，相(xiang)對密度為8.9，為鎂的五倍。比普(pu)通(tong)鋼還重約15%。其具有玫瑰紅(hong)色(se)(se)，表面形成氧(yang)化膜后呈紫(zi)色(se)(se)，故一般稱為紫(zi)銅(tong)(tong)。它是含有一定氧(yang)的銅(tong)(tong)，因(yin)而又稱含氧(yang)銅(tong)(tong)。
C1100特性(xing)及適用范(fan)圍
紫銅有良好的導(dao)電(dian)(dian)、導(dao)熱(re)、耐(nai)蝕和(he)(he)加(jia)工性(xing)(xing)能,可以焊接和(he)(he)釬焊。含降低導(dao)電(dian)(dian)、導(dao)熱(re)性(xing)(xing)雜質較少,微(wei)量的氧對導(dao)電(dian)(dian)、導(dao)熱(re)和(he)(he)加(jia)工等(deng)性(xing)(xing)能影響不(bu)大(da)，但易引(yin)起“氫(qing)病”，不(bu)宜(yi)在高溫(wen)（如>370℃）還原性(xing)(xing)氣氛中(zhong)加(jia)工（退(tui)火、焊接等(deng)）和(he)(he)使用。
C1100紫(zi)銅(tong)(tong)(tong)(tong)(tong)用(yong)(yong)途比純(chun)(chun)(chun)(chun)(chun)(chun)鐵廣泛得多，每年有50%的(de)(de)(de)(de)銅(tong)(tong)(tong)(tong)(tong)被(bei)電(dian)(dian)解(jie)提純(chun)(chun)(chun)(chun)(chun)(chun)為純(chun)(chun)(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)(tong)，用(yong)(yong)于電(dian)(dian)氣工業。這(zhe)里所說的(de)(de)(de)(de)紫(zi)銅(tong)(tong)(tong)(tong)(tong)，確實要非常純(chun)(chun)(chun)(chun)(chun)(chun)，含銅(tong)(tong)(tong)(tong)(tong)達99.95%以上才行。極(ji)少(shao)量的(de)(de)(de)(de)雜(za)質(zhi)，特別是磷、砷、鋁等，會大(da)大(da)降低銅(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)(de)導(dao)電(dian)(dian)率。銅(tong)(tong)(tong)(tong)(tong)中含氧(yang)(煉銅(tong)(tong)(tong)(tong)(tong)時容易混入少(shao)量氧(yang))對導(dao)電(dian)(dian)率影(ying)響很(hen)大(da)，用(yong)(yong)于電(dian)(dian)氣工業的(de)(de)(de)(de)銅(tong)(tong)(tong)(tong)(tong)一(yi)般(ban)都必(bi)須是無氧(yang)銅(tong)(tong)(tong)(tong)(tong)。另(ling)外，鉛、銻(ti)、鉍等雜(za)質(zhi)會使銅(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)(de)結晶不(bu)能結合在(zai)一(yi)起(qi)，造成(cheng)熱脆(cui)，也(ye)會影(ying)響純(chun)(chun)(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)(de)加(jia)工。這(zhe)種純(chun)(chun)(chun)(chun)(chun)(chun)度很(hen)高的(de)(de)(de)(de)純(chun)(chun)(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)(tong)，一(yi)般(ban)用(yong)(yong)電(dian)(dian)解(jie)法精制：把不(bu)純(chun)(chun)(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)(tong)(即粗銅(tong)(tong)(tong)(tong)(tong))作陽極(ji)，純(chun)(chun)(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)(tong)作陰極(ji)，以硫酸銅(tong)(tong)(tong)(tong)(tong)溶液為電(dian)(dian)解(jie)液。當(dang)電(dian)(dian)流通過后，陽極(ji)上不(bu)純(chun)(chun)(chun)(chun)(chun)(chun)的(de)(de)(de)(de)銅(tong)(tong)(tong)(tong)(tong)逐(zhu)漸(jian)熔(rong)解(jie)，純(chun)(chun)(chun)(chun)(chun)(chun)銅(tong)(tong)(tong)(tong)(tong)便逐(zhu)漸(jian)沉淀(dian)在(zai)陰極(ji)上。這(zhe)樣精制而得的(de)(de)(de)(de)銅(tong)(tong)(tong)(tong)(tong);純(chun)(chun)(chun)(chun)(chun)(chun)度可達99.99%。
