裸銅(tong)(tong)(tong)線就是用純銅(tong)(tong)(tong)桿拉絲而成的(de)銅(tong)(tong)(tong)線，質(zhi)料單一(yi)，表里皆銅(tong)(tong)(tong)金屬，外觀看過去(qu)為黃色，且因銅(tong)(tong)(tong)純度的(de)高低使顏色有深有淺。物理性能(neng)上，裸銅(tong)(tong)(tong)線材質(zhi)柔(rou)軟，導(dao)電性能(neng)優良。 

鍍(du)錫銅(tong)(tong)(tong)線(xian)(xian)的(de)(de)工藝(yi)比裸銅(tong)(tong)(tong)線(xian)(xian)稍(shao)稍(shao)復雜(za)些,UL1007，UL1015，UL1061，UL1571，UL1095，UL1430電(dian)子線(xian)(xian)，UL彩排(pai)線(xian)(xian)，UL2651灰排(pai)線(xian)(xian)，UL2468，UL端子線(xian)(xian)，UL導線(xian)(xian)，UL軟排(pai)線(xian)(xian)，PE線(xian)(xian)，UL1332，UL1333，UL3132，UL3135，UL3239，UL1672雙層絕緣(yuan)線(xian)(xian),UL20080軟排(pai)線(xian)(xian),熱宿管，鐵氟龍管，硅膠管 將純銅(tong)(tong)(tong)桿拉成絲(si)后(hou)再(zai)用熱鍍(du)錫工藝(yi)在銅(tong)(tong)(tong)絲(si)表(biao)面(mian)鍍(du)上薄薄的(de)(de)一(yi)層錫就成了鍍(du)錫銅(tong)(tong)(tong)線(xian)(xian)。這種線(xian)(xian)外觀為銀色，因為錫是銀色金屬的(de)(de)緣(yuan)故。鍍(du)錫銅(tong)(tong)(tong)線(xian)(xian)，材質比較柔軟，導電(dian)性(xing)能(neng)良(liang)好，與裸銅(tong)(tong)(tong)線(xian)(xian)相比，其耐蝕性(xing)、抗氧化性(xing)能(neng)更強(qiang)，可大大延長弱電(dian)線(xian)(xian)纜的(de)(de)使(shi)用壽(shou)命。
