電鍍銅包鋁/電鍍銅包鋁鎂：
銅包(bao)鋁絲及銅包(bao)鋁鎂合金(jin)絲的特點及用途
銅(tong)(tong)(tong)包(bao)鋁絲(si)(si)(si)(si)(si)(CCA)及銅(tong)(tong)(tong)包(bao)鋁鎂(mei)合(he)金絲(si)(si)(si)(si)(si) (CCAM)是(shi)(shi)在(zai)鋁絲(si)(si)(si)(si)(si) 、鋁鎂(mei)合(he)金絲(si)(si)(si)(si)(si)的(de)(de)表面鍍一(yi)層一(yi)定厚(hou)度(du)的(de)(de)銅(tong)(tong)(tong),使(shi)之成為一(yi)種高性能的(de)(de)新型金屬(shu)絲(si)(si)(si)(si)(si)。銅(tong)(tong)(tong)層截面積(ji)約(yue)占絲(si)(si)(si)(si)(si)材截面積(ji)的(de)(de)10%,厚(hou)度(du)大(da)約(yue)是(shi)(shi)半經的(de)(de)3.5%;銅(tong)(tong)(tong)包(bao)絲(si)(si)(si)(si)(si)導電率大(da)約(yue)是(shi)(shi)銅(tong)(tong)(tong)絲(si)(si)(si)(si)(si)的(de)(de)62.9%,體積(ji)質量(liang)約(yue)為3.32g/立方厘米 ,是(shi)(shi)銅(tong)(tong)(tong)絲(si)(si)(si)(si)(si)的(de)(de)37.3%, 同樣質量(liang)的(de)(de)銅(tong)(tong)(tong)包(bao)鋁絲(si)(si)(si)(si)(si)或銅(tong)(tong)(tong)包(bao)鋁鎂(mei)合(he)金絲(si)(si)(si)(si)(si)的(de)(de)長(chang)度(du)是(shi)(shi)純(chun)銅(tong)(tong)(tong)絲(si)(si)(si)(si)(si)材長(chang)度(du)的(de)(de)2.7倍 ,這 樣可節約(yue)大(da)量(liang)的(de)(de)銅(tong)(tong)(tong)資源 , 使(shi)其在(zai)現代工程中得到(dao)廣(guang)泛的(de)(de)應用。
