　　我公司專業生產銅包鋼絲，鍍(du)銅(tong)(tong)(tong)鍍(du)鋅鐵(tie)絲(si)，鍍(du)黃銅(tong)(tong)(tong)絲(si)，鍍(du)銅(tong)(tong)(tong)電(dian)焊網，主要生產直徑(jing)(jing)為0.09-2.00MM,導電(dian)率18%-40%軟態及硬態的(de)銅(tong)(tong)(tong)包(bao)鋼(gang)絲(si). 直徑(jing)(jing)為0.10-1.20MM鍍(du)黃銅(tong)(tong)(tong)包(bao)鋼(gang)絲(si)(膠管鋼(gang)絲(si),橡膠軟管增強(qiang)用鋼(gang)絲(si))成本低,光亮度好,軟硬度控制得當,是(shi)替代純銅(tong)(tong)(tong)絲(si)的(de)最佳(jia)產品. 主要用于增強(qiang)橡膠軟管,其技(ji)術指標符合GB11182-89標準。

　　屈(qu)服強(qiang)度σs及變(bian)(bian)(bian)形(xing)(xing)抗(kang)力尺可(ke)能(neng)的(de)小(xiao)，這樣(yang)可(ke)使(shi)單位變(bian)(bian)(bian)形(xing)(xing)力相(xiang)(xiang)應減小(xiao)，以延長模(mo)具壽(shou)命。鋼(gang)材的(de)冷(leng)變(bian)(bian)(bian)形(xing)(xing)性能(neng)要(yao)好(hao)，即材料應有(you)較好(hao)的(de)塑(su)性，較低的(de)硬度，能(neng)在(zai)較大的(de)變(bian)(bian)(bian)形(xing)(xing)程(cheng)度下(xia)不致(zhi)引起產品開裂。通常使(shi)用的(de)有(you)調質型(xing)合(he)金鋼(gang)、低溫回(hui)火(huo)型(xing)合(he)金結構鋼(gang)、低碳低合(he)金高強(qiang)度鋼(gang)、鐵素體-馬氏體雙相(xiang)(xiang)鋼(gang)等(deng)。

　　銅(tong)包鋼線是以軟鋼或硬鋼作為芯(xin)材，表面鍍上一(yi)層均勻的銅(tong)層，具(ju)有優良(liang)的導(dao)(dao)(dao)電(dian)性。銅(tong)的密(mi)著性好(hao)，不會因為熱(re)處理(li)或機械(xie)加工(gong)等造成(cheng)剝落(luo)。具(ju)有適度(du)(du)的機械(xie)強度(du)(du)和柔韌性。銅(tong)層的厚度(du)(du)：銅(tong)層厚度(du)(du)之特性以導(dao)(dao)(dao)電(dian)率(lv)(lv)表示，分為導(dao)(dao)(dao)電(dian)率(lv)(lv)30%及40%兩(liang)種(zhong)。7
