一般用電解銅(tong)(tong)(tong)生產，電阻(zu)率低(di)于低(di)氧(yang)銅(tong)(tong)(tong)桿(gan)，因此在(zai)生產對電阻(zu)要求比較(jiao)苛刻的產品中(zhong)，無(wu)(wu)氧(yang)銅(tong)(tong)(tong)桿(gan)比較(jiao)經濟；制造無(wu)(wu)氧(yang)銅(tong)(tong)(tong)桿(gan)要求質量(liang)較(jiao)高的原材(cai)料(liao)；無(wu)(wu)氧(yang)銅(tong)(tong)(tong)桿(gan)顯得(de)更(geng)為優(you)越的是拉(la)制直徑<0.5mm的銅(tong)(tong)(tong)線。6MM的無(wu)(wu)氧(yang)銅(tong)(tong)(tong)桿(gan)用于生產銅(tong)(tong)(tong)扁線。

1、處(chu)理工藝：除(chu)(chu)油除(chu)(chu)銹除(chu)(chu)氧(yang)化(hua)皮——水洗(xi)(xi)——酸(suan)洗(xi)(xi)拋(pao)(pao)光——水洗(xi)(xi)——中(zhong)和——水洗(xi)(xi)——著色處(chu)理——水洗(xi)(xi)——干燥(zao)及其(qi)它后處(chu)理　。　2、酸(suan)洗(xi)(xi)拋(pao)(pao)光推薦使用銅材酸(suan)洗(xi)(xi)拋(pao)(pao)光液進行(xing)處(chu)理。目的(de)是(shi)使黃銅表面具有光澤。　3、本品為(wei)工作(zuo)液，將工件浸泡(pao)于本品中(zhong)，2分鐘(zhong)左右(you)黃銅表面即變(bian)成黑青色，根據實(shi)驗結(jie)果。浸泡(pao)時間為(wei)20－25分鐘(zhong)時，表面變(bian)色質(zhi)量好，可獲(huo)得(de)較好的(de)防銹性能(neng)。工件可重(zhong)復浸泡(pao)，增加變(bian)色層厚(hou)度，可獲(huo)得(de)滿意效果。　4、如想達到(dao)古銅色，經(jing)上述步驟(zou)處(chu)理后，可用砂(sha)紙摩擦，方可達到(dao)理想的(de)效果。
