箔材(cai)(cai)：極(ji)薄的金屬片或帶(dai)材(cai)(cai)。大多數(shu)金屬以(yi)及它們的合金都能制成箔材(cai)(cai)。

       用途：

       箔(bo)(bo)(bo)(bo)(bo)材(cai)的(de)(de)(de)用(yong)途(tu)十分廣泛，這(zhe)是制(zhi)(zhi)箔(bo)(bo)(bo)(bo)(bo)金(jin)(jin)屬的(de)(de)(de)特(te)點和(he)箔(bo)(bo)(bo)(bo)(bo)材(cai)本身(shen)特(te)點決定的(de)(de)(de)。例如鋼及(ji)合(he)(he)金(jin)(jin)箔(bo)(bo)(bo)(bo)(bo)主要用(yong)于電(dian)(dian)子(zi)、航空航天(tian)、儀器(qi)(qi)儀表等(deng)(deng)部門；鐵(tie)鎳軟磁(ci)(ci)合(he)(he)金(jin)(jin)箔(bo)(bo)(bo)(bo)(bo)材(cai)用(yong)于制(zhi)(zhi)作微型高頻脈(mo)沖變壓器(qi)(qi)、開關線圈(quan)、磁(ci)(ci)記錄(lu)器(qi)(qi)、磁(ci)(ci)放大器(qi)(qi)等(deng)(deng)的(de)(de)(de)鐵(tie)芯；鈦(tai)(tai)合(he)(he)金(jin)(jin)箔(bo)(bo)(bo)(bo)(bo)用(yong)于制(zhi)(zhi)作噴氣發(fa)動機燃燒管(guan)上的(de)(de)(de)飾網、航天(tian)飛(fei)機防熱(re)系(xi)統中(zhong)的(de)(de)(de)金(jin)(jin)屬復(fu)合(he)(he)防熱(re)瓦和(he)鈦(tai)(tai)多(duo)層(ceng)壁；鎢鉬等(deng)(deng)箔(bo)(bo)(bo)(bo)(bo)材(cai)用(yong)于特(te)殊電(dian)(dian)子(zi)管(guan)及(ji)發(fa)熱(re)元(yuan)(yuan)件；銅鎳和(he)鎳鉻電(dian)(dian)阻合(he)(he)金(jin)(jin)箔(bo)(bo)(bo)(bo)(bo)材(cai)用(yong)于制(zhi)(zhi)作測力(li)應變片(pian)、精(jing)密電(dian)(dian)阻和(he)錄(lu)音錄(lu)像(xiang)磁(ci)(ci)頭(tou)間(jian)隙(xi)片(pian)；不銹(xiu)鋼箔(bo)(bo)(bo)(bo)(bo)用(yong)于制(zhi)(zhi)作精(jing)密儀器(qi)(qi)中(zhong)高靈(ling)敏度壓力(li)元(yuan)(yuan)件上的(de)(de)(de)隔片(pian)、蒸汽渦輪發(fa)動機中(zhong)主要結構材(cai)料和(he)熱(re)交換材(cai)料等(deng)(deng)。鋁箔(bo)(bo)(bo)(bo)(bo)、鉛箔(bo)(bo)(bo)(bo)(bo)、銅箔(bo)(bo)(bo)(bo)(bo)和(he)康銅箔(bo)(bo)(bo)(bo)(bo)的(de)(de)(de)用(yong)途(tu)見鋁箔(bo)(bo)(bo)(bo)(bo)生產(chan)、鉛箔(bo)(bo)(bo)(bo)(bo)生產(chan)、電(dian)(dian)解銅箔(bo)(bo)(bo)(bo)(bo)生產(chan)和(he)康銅箔(bo)(bo)(bo)(bo)(bo)生產(chan)。

       制造方法：

       箔(bo)材的(de)(de)(de)制(zhi)(zhi)造(zao)方(fang)法(fa)(fa)(fa)以平(ping)輥(gun)(gun)帶(dai)式軋(ya)(ya)制(zhi)(zhi)較(jiao)為廣泛，其(qi)生(sheng)(sheng)產率(lv)高，規(gui)模和(he)產量大。對(dui)于比較(jiao)軟的(de)(de)(de)金(jin)(jin)屬(shu)如(ru)鋁(lv)和(he)鋁(lv)合金(jin)(jin)箔(bo)、鉛箔(bo)和(he)錫箔(bo)等，可(ke)用(yong)(yong)(yong)四輥(gun)(gun)或(huo)二輥(gun)(gun)軋(ya)(ya)機(ji)(ji)軋(ya)(ya)得；若采(cai)(cai)用(yong)(yong)(yong)雙(shuang)合軋(ya)(ya)制(zhi)(zhi)可(ke)軋(ya)(ya)得0.007mm厚(hou)的(de)(de)(de)鋁(lv)箔(bo)。對(dui)于變形(xing)抗力高的(de)(de)(de)金(jin)(jin)屬(shu)，如(ru)鋼、鈦、鎳、銅以及鎢、鉬、鉭(tan)、鈮(ni)的(de)(de)(de)箔(bo)材，則應采(cai)(cai)用(yong)(yong)(yong)輥(gun)(gun)徑(jing)細、剛度大的(de)(de)(de)軋(ya)(ya)機(ji)(ji)軋(ya)(ya)制(zhi)(zhi)，如(ru)森吉米爾軋(ya)(ya)機(ji)(ji)和(he)羅恩(en)軋(ya)(ya)機(ji)(ji)，這一類軋(ya)(ya)機(ji)(ji)的(de)(de)(de)細輥(gun)(gun)徑(jing)可(ke)達幾毫米到十幾毫米，可(ke)將軋(ya)(ya)件單層軋(ya)(ya)到0.001mm，但輥(gun)(gun)身(shen)長度不(bu)大。另外(wai)也可(ke)采(cai)(cai)用(yong)(yong)(yong)異(yi)步軋(ya)(ya)制(zhi)(zhi)。除軋(ya)(ya)制(zhi)(zhi)法(fa)(fa)(fa)外(wai)在(zai)工業(ye)上(shang)也采(cai)(cai)用(yong)(yong)(yong)電解沉(chen)積(ji)法(fa)(fa)(fa)制(zhi)(zhi)造(zao)印刷電路板用(yong)(yong)(yong)的(de)(de)(de)銅箔(bo)和(he)用(yong)(yong)(yong)真空蒸鍍法(fa)(fa)(fa)制(zhi)(zhi)造(zao)包裝用(yong)(yong)(yong)的(de)(de)(de)鋁(lv)箔(bo)。金(jin)(jin)箔(bo)仍采(cai)(cai)用(yong)(yong)(yong)古老的(de)(de)(de)錘鍛拍打(da)法(fa)(fa)(fa)生(sheng)(sheng)產。箔(bo)材通常是(shi)切成用(yong)(yong)(yong)戶(hu)要求的(de)(de)(de)寬度并纏在(zai)特制(zhi)(zhi)的(de)(de)(de)軸芯上(shang)成卷供應的(de)(de)(de)，卷重也按用(yong)(yong)(yong)戶(hu)的(de)(de)(de)要求而定。
