根(gen)據鍍(du)(du)(du)件(jian)(jian)表面積和鍍(du)(du)(du)件(jian)(jian)的(de)(de)(de)(de)重童選擇(ze)銅(tong)(tong)絲(si)(si)(si)(si)的(de)(de)(de)(de)直徑，應(ying)(ying)在能(neng)(neng)使電(dian)流正常(chang)暢通，并(bing)能(neng)(neng)承(cheng)受(shou)(shou)懸掛重談的(de)(de)(de)(de)前(qian)提(ti)下，盡最小一(yi)點.銅(tong)(tong)絲(si)(si)(si)(si)過(guo)(guo)(guo)粗，除對鍍(du)(du)(du)件(jian)(jian)會(hui)造成過(guo)(guo)(guo)大面積的(de)(de)(de)(de)遮蓋(gai)之外(wai)，還可能(neng)(neng)導致鍍(du)(du)(du)件(jian)(jian)變形(xing);銅(tong)(tong)絲(si)(si)(si)(si)過(guo)(guo)(guo)細(xi)(xi)(xi)，除承(cheng)受(shou)(shou)不(bu)了鍍(du)(du)(du)件(jian)(jian)重量(liang)外(wai)，還可能(neng)(neng)影響(xiang)到所(suo)需電(dian)流的(de)(de)(de)(de)通過(guo)(guo)(guo)而不(bu)能(neng)(neng)獲得(de)正常(chang)的(de)(de)(de)(de)鍍(du)(du)(du)層(ceng)質(zhi)量(liang)。另外(wai)，受(shou)(shou)鍍(du)(du)(du)的(de)(de)(de)(de)鍍(du)(du)(du)種也是應(ying)(ying)考慮的(de)(de)(de)(de)因素。例如，在綁扎(zha)鍍(du)(du)(du)亮鎳件(jian)(jian)時(shi)(shi)，銅(tong)(tong)絲(si)(si)(si)(si)不(bu)宜選得(de)過(guo)(guo)(guo)細(xi)(xi)(xi)。因為亮鎳很(hen)脆，若鋼絲(si)(si)(si)(si)過(guo)(guo)(guo)分細(xi)(xi)(xi)小。就(jiu)有可能(neng)(neng)在電(dian)鍍(du)(du)(du)時(shi)(shi)因陰極(ji)棒(bang)的(de)(de)(de)(de)移動或(huo)鍍(du)(du)(du)件(jian)(jian)出枯(ku)時(shi)(shi)受(shou)(shou)力而被折斷。當綁扎(zha)已經鍍(du)(du)(du)鎳并(bing)經拋光過(guo)(guo)(guo)的(de)(de)(de)(de)裝飾性鍍(du)(du)(du)鉻件(jian)(jian)時(shi)(shi)，所(suo)用(yong)的(de)(de)(de)(de)銅(tong)(tong)絲(si)(si)(si)(si)則宜適(shi)當選得(de)細(xi)(xi)(xi)點，以減輕銅(tong)(tong)絲(si)(si)(si)(si)在鍍(du)(du)(du)件(jian)(jian)上的(de)(de)(de)(de)遮蓋(gai)面，且該銅(tong)(tong)絲(si)(si)(si)(si)應(ying)(ying)先經鍍(du)(du)(du)一(yi)層(ceng)鉻才可使用(yong)，否則綁扎(zha)處難免(mian)產(chan)生銅(tong)(tong)絲(si)(si)(si)(si)影。一(yi)般(ban)情況下，不(bu)宜用(yong)雙股鋼絲(si)(si)(si)(si)綁扎(zha)鍍(du)(du)(du)件(jian)(jian)，否則極(ji)容易產(chan)生銅(tong)(tong)絲(si)(si)(si)(si)影。
