康(kang)銅(tong)絲實際(ji)上是一種以銅(tong)鎳(nie)為(wei)主(zhu)要成分(fen)的電(dian)(dian)阻(zu)(zu)合(he)(he)(he)金。電(dian)(dian)阻(zu)(zu)溫度(du)(du)(du)系(xi)數相(xiang)(xiang)(xiang)對(dui)較低，應(ying)用(yong)環(huan)境(jing)溫度(du)(du)(du)相(xiang)(xiang)(xiang)對(dui)較寬(480℃以下)，加工(gong)(gong)性(xing)能優異，焊(han)接(jie)性(xing)能好(hao)。關(guan)鍵可用(yong)于制造儀表(biao)設備，電(dian)(dian)子(zi)(zi)也有(you)工(gong)(gong)業(ye)設備中的電(dian)(dian)子(zi)(zi)元件。此外，還有(you)一種新型的康(kang)銅(tong)電(dian)(dian)阻(zu)(zu)合(he)(he)(he)金，是銅(tong)鐵基合(he)(he)(he)金，電(dian)(dian)阻(zu)(zu)與康(kang)銅(tong)相(xiang)(xiang)(xiang)同(tong)(tong)，電(dian)(dian)阻(zu)(zu)溫度(du)(du)(du)系(xi)數基本相(xiang)(xiang)(xiang)同(tong)(tong)，應(ying)用(yong)溫度(du)(du)(du)相(xiang)(xiang)(xiang)同(tong)(tong)。與康(kang)銅(tong)電(dian)(dian)阻(zu)(zu)合(he)(he)(he)金相(xiang)(xiang)(xiang)比(bi)，康(kang)銅(tong)電(dian)(dian)阻(zu)(zu)合(he)(he)(he)金不含(han)高價鎳(nie)，但價格優異，但抗氧化能力(li)比(bi)康(kang)銅(tong)負載電(dian)(dian)阻(zu)(zu)合(he)(he)(he)金差。
