箔材(cai)：極(ji)薄的(de)金(jin)(jin)屬片或帶材(cai)。大多數金(jin)(jin)屬以(yi)及它們的(de)合金(jin)(jin)都能(neng)制(zhi)成箔材(cai)。

       用途：

       箔(bo)材(cai)的(de)用(yong)(yong)途十分廣泛，這(zhe)是制箔(bo)金屬(shu)(shu)的(de)特點和(he)箔(bo)材(cai)本身(shen)特點決(jue)定的(de)。例如鋼及合金箔(bo)主(zhu)要(yao)用(yong)(yong)于(yu)電(dian)(dian)子(zi)、航(hang)空航(hang)天、儀器(qi)(qi)儀表(biao)等(deng)(deng)部門；鐵鎳軟(ruan)磁合金箔(bo)材(cai)用(yong)(yong)于(yu)制作(zuo)微型高頻脈(mo)沖變壓器(qi)(qi)、開關線圈、磁記錄器(qi)(qi)、磁放大器(qi)(qi)等(deng)(deng)的(de)鐵芯；鈦合金箔(bo)用(yong)(yong)于(yu)制作(zuo)噴氣發動機燃燒管上的(de)飾網、航(hang)天飛(fei)機防熱系統中的(de)金屬(shu)(shu)復合防熱瓦(wa)和(he)鈦多層壁；鎢鉬等(deng)(deng)箔(bo)材(cai)用(yong)(yong)于(yu)特殊電(dian)(dian)子(zi)管及發熱元(yuan)件；銅(tong)鎳和(he)鎳鉻電(dian)(dian)阻合金箔(bo)材(cai)用(yong)(yong)于(yu)制作(zuo)測力應變片、精密電(dian)(dian)阻和(he)錄音錄像(xiang)磁頭間(jian)隙片；不銹(xiu)鋼箔(bo)用(yong)(yong)于(yu)制作(zuo)精密儀器(qi)(qi)中高靈敏度壓力元(yuan)件上的(de)隔片、蒸汽渦輪發動機中主(zhu)要(yao)結構材(cai)料和(he)熱交換(huan)材(cai)料等(deng)(deng)。鋁(lv)(lv)箔(bo)、鉛箔(bo)、銅(tong)箔(bo)和(he)康銅(tong)箔(bo)的(de)用(yong)(yong)途見鋁(lv)(lv)箔(bo)生(sheng)產(chan)、鉛箔(bo)生(sheng)產(chan)、電(dian)(dian)解銅(tong)箔(bo)生(sheng)產(chan)和(he)康銅(tong)箔(bo)生(sheng)產(chan)。

       制造方法：

       箔材(cai)的(de)(de)制造方法以平輥帶(dai)式軋(ya)(ya)(ya)(ya)(ya)制較為(wei)廣泛，其生(sheng)產率(lv)高，規模和(he)產量(liang)大(da)。對(dui)于比較軟(ruan)的(de)(de)金(jin)屬(shu)如鋁(lv)和(he)鋁(lv)合金(jin)箔、鉛箔和(he)錫箔等(deng)，可(ke)(ke)用(yong)(yong)四(si)輥或二輥軋(ya)(ya)(ya)(ya)(ya)機(ji)軋(ya)(ya)(ya)(ya)(ya)得；若采(cai)(cai)(cai)用(yong)(yong)雙(shuang)合軋(ya)(ya)(ya)(ya)(ya)制可(ke)(ke)軋(ya)(ya)(ya)(ya)(ya)得0.007mm厚的(de)(de)鋁(lv)箔。對(dui)于變形抗力高的(de)(de)金(jin)屬(shu)，如鋼(gang)、鈦、鎳、銅以及鎢、鉬、鉭、鈮的(de)(de)箔材(cai)，則應(ying)采(cai)(cai)(cai)用(yong)(yong)輥徑細(xi)、剛(gang)度(du)(du)大(da)的(de)(de)軋(ya)(ya)(ya)(ya)(ya)機(ji)軋(ya)(ya)(ya)(ya)(ya)制，如森(sen)吉米(mi)爾軋(ya)(ya)(ya)(ya)(ya)機(ji)和(he)羅恩軋(ya)(ya)(ya)(ya)(ya)機(ji)，這一(yi)類軋(ya)(ya)(ya)(ya)(ya)機(ji)的(de)(de)細(xi)輥徑可(ke)(ke)達幾(ji)毫(hao)米(mi)到十幾(ji)毫(hao)米(mi)，可(ke)(ke)將軋(ya)(ya)(ya)(ya)(ya)件單層軋(ya)(ya)(ya)(ya)(ya)到0.001mm，但輥身長度(du)(du)不大(da)。另外也(ye)(ye)可(ke)(ke)采(cai)(cai)(cai)用(yong)(yong)異步軋(ya)(ya)(ya)(ya)(ya)制。除(chu)軋(ya)(ya)(ya)(ya)(ya)制法外在工業上(shang)也(ye)(ye)采(cai)(cai)(cai)用(yong)(yong)電(dian)解(jie)沉積法制造印(yin)刷電(dian)路板用(yong)(yong)的(de)(de)銅箔和(he)用(yong)(yong)真空蒸鍍法制造包裝(zhuang)用(yong)(yong)的(de)(de)鋁(lv)箔。金(jin)箔仍采(cai)(cai)(cai)用(yong)(yong)古老的(de)(de)錘鍛拍打法生(sheng)產。箔材(cai)通常是(shi)切(qie)成(cheng)用(yong)(yong)戶要(yao)求(qiu)的(de)(de)寬度(du)(du)并纏在特制的(de)(de)軸芯(xin)上(shang)成(cheng)卷(juan)供應(ying)的(de)(de)，卷(juan)重也(ye)(ye)按用(yong)(yong)戶的(de)(de)要(yao)求(qiu)而定。
