一般用(yong)(yong)電(dian)解銅(tong)(tong)生(sheng)產，電(dian)阻率(lv)低(di)(di)于低(di)(di)氧(yang)銅(tong)(tong)桿，因此在生(sheng)產對電(dian)阻要求(qiu)比較(jiao)苛(ke)刻的產品(pin)中，無氧(yang)銅(tong)(tong)桿比較(jiao)經濟；制造無氧(yang)銅(tong)(tong)桿要求(qiu)質(zhi)量較(jiao)高的原材(cai)料；無氧(yang)銅(tong)(tong)桿顯得(de)更為(wei)優(you)越的是拉制直徑<0.5mm的銅(tong)(tong)線。6MM的無氧(yang)銅(tong)(tong)桿用(yong)(yong)于生(sheng)產銅(tong)(tong)扁線。

1、處(chu)理(li)(li)(li)(li)工(gong)(gong)藝：除(chu)油(you)除(chu)銹(xiu)除(chu)氧化皮——水(shui)洗(xi)——酸洗(xi)拋光(guang)——水(shui)洗(xi)——中(zhong)和——水(shui)洗(xi)——著色(se)處(chu)理(li)(li)(li)(li)——水(shui)洗(xi)——干燥及其它后(hou)處(chu)理(li)(li)(li)(li)　。　2、酸洗(xi)拋光(guang)推薦使(shi)用銅(tong)材酸洗(xi)拋光(guang)液(ye)進行處(chu)理(li)(li)(li)(li)。目的(de)是(shi)使(shi)黃銅(tong)表(biao)(biao)面具有光(guang)澤。　3、本品為工(gong)(gong)作(zuo)液(ye)，將(jiang)工(gong)(gong)件(jian)浸(jin)(jin)泡(pao)于本品中(zhong)，2分鐘左右黃銅(tong)表(biao)(biao)面即(ji)變(bian)(bian)成黑青色(se)，根據實驗結果。浸(jin)(jin)泡(pao)時(shi)間(jian)為20－25分鐘時(shi)，表(biao)(biao)面變(bian)(bian)色(se)質量好(hao)，可獲(huo)得較好(hao)的(de)防銹(xiu)性能。工(gong)(gong)件(jian)可重復浸(jin)(jin)泡(pao)，增(zeng)加變(bian)(bian)色(se)層厚度(du)，可獲(huo)得滿意效果。　4、如想達到(dao)古銅(tong)色(se)，經上述步(bu)驟處(chu)理(li)(li)(li)(li)后(hou)，可用砂紙(zhi)摩(mo)擦，方可達到(dao)理(li)(li)(li)(li)想的(de)效果。
