銅(tong)包(bao)(bao)鋁(lv)和銅(tong)包(bao)(bao)鋁(lv)鎂(mei)(mei)雖只差一個字，但(dan)其特性但(dan)是決(jue)然(ran)不(bu)同的(de)，銅(tong)包(bao)(bao)鋁(lv)是包(bao)(bao)的(de)純鋁(lv)，銅(tong)包(bao)(bao)鋁(lv)鎂(mei)(mei)是包(bao)(bao)的(de)是鎂(mei)(mei)鋁(lv)合金，銅(tong)包(bao)(bao)鋁(lv)電阻小，耗電量少(shao)發燙(tang)少(shao)，銅(tong)包(bao)(bao)鋁(lv)鎂(mei)(mei)抗壓強度高，耐腐蝕。
銅(tong)(tong)包(bao)(bao)(bao)(bao)鋁(lv)(lv)和銅(tong)(tong)包(bao)(bao)(bao)(bao)鋁(lv)(lv)鎂(mei)的首要區別(bie)取決于銅(tong)(tong)線的材料，一個(ge)(ge)是電焊工(gong)鋁(lv)(lv)一個(ge)(ge)是鎂(mei)鋁(lv)(lv)合金，電鍍工(gong)藝(yi)銅(tong)(tong)包(bao)(bao)(bao)(bao)鋁(lv)(lv)和包(bao)(bao)(bao)(bao)覆銅(tong)(tong)包(bao)(bao)(bao)(bao)鋁(lv)(lv)有(you)實質不(bu)(bu)一樣，電鍍工(gong)藝(yi)銅(tong)(tong)包(bao)(bao)(bao)(bao)鋁(lv)(lv)因為表(biao)面的銅(tong)(tong)層(ceng)是沉淀(dian)在絲(si)表(biao)面，銅(tong)(tong)層(ceng)自身沒有(you)抗壓(ya)強度(du)，因而(er)在拉制(zhi)細(xi)絲(si)時，假如銅(tong)(tong)層(ceng)掉下來，絲(si)也不(bu)(bu)會破裂可(ke)以再次(ci)拉制(zhi)，但包(bao)(bao)(bao)(bao)覆銅(tong)(tong)包(bao)(bao)(bao)(bao)鋁(lv)(lv)則不(bu)(bu)一樣，包(bao)(bao)(bao)(bao)覆銅(tong)(tong)包(bao)(bao)(bao)(bao)鋁(lv)(lv)的銅(tong)(tong)層(ceng)要遠比芯(xin)部的鋁(lv)(lv)抗壓(ya)強度(du)高許多，拉制(zhi)細(xi)絲(si)時，一旦銅(tong)(tong)層(ceng)有(you)缺陷則馬上斷絲(si)，那樣就不(bu)(bu)可(ke)能有(you)漏鋁(lv)(lv)的次(ci)絲(si)滲(shen)入制(zhi)成品。
