TU1無氧銅

TU1無(wu)(wu)氧(yang)銅帶,無(wu)(wu)氧(yang)銅無(wu)(wu)氫脆(cui)現象,導(dao)電率高,加工性(xing)(xing)能(neng)(neng)和(he)焊接性(xing)(xing)能(neng)(neng)、耐蝕性(xing)(xing)能(neng)(neng)和(he)低溫(wen)性(xing)(xing)能(neng)(neng)均好的材料(liao)。

簡介


品名:TU1無(wu)氧(yang)銅(tong)帶(dai)

無氧銅(tong)是(shi)不含氧也不含任何脫氧劑殘(can)留物(wu)的(de)純銅(tong)。但實際上(shang)還是(shi)含有非常微(wei)量氧和(he)一些雜(za)質。按標準(zhun)規定,氧的(de)含量不大(da)于0.03%,雜(za)質總含量不大(da)于0.05%,銅(tong)的(de)純度大(da)于99.95%。

根據含(han)氧量和(he)雜質含(han)量,無氧銅又分(fen)為一號(hao)(hao)和(he)二(er)號(hao)(hao)無氧銅。一號(hao)(hao)無氧銅純度(du)(du)達到99.97%,氧含(han)量不大于0.003%,雜質總含(han)量不大于0.03%;二(er)號(hao)(hao)無氧銅純度(du)(du)達到99.95%,氧含(han)量不大于0.003%,雜質總含(han)量不大于0.05%。

無氧(yang)銅無氫脆(cui)現(xian)象(xiang),導電(dian)率高(gao),加工性能(neng)(neng)和焊接(jie)性能(neng)(neng)、耐(nai)蝕性能(neng)(neng)和低(di)溫(wen)性能(neng)(neng)均好。

TU1無(wu)氧(yang)(yang)(yang)(yang)(yang)銅(tong)(tong)(tong)板(ban)帶(dai)材是(shi)電真(zhen)(zhen)空(kong)行(xing)業的(de)(de)(de)關鍵材料,由(you)于電真(zhen)(zhen)空(kong)器(qi)件如大功率(lv)發(fa)(fa)射管、磁控管、行(xing)波管、真(zhen)(zhen)空(kong)電容器(qi)、真(zhen)(zhen)空(kong)開關等(deng),均(jun)需要在 920 ℃ 的(de)(de)(de)高(gao)(gao)溫下,在氫氣(qi)(qi)中進行(xing)釬焊,此時氫氣(qi)(qi)與銅(tong)(tong)(tong)中的(de)(de)(de)氧(yang)(yang)(yang)(yang)(yang)會發(fa)(fa)生 Cu 2 O+H 2 → Cu+H 2 O 反應(ying),所產生的(de)(de)(de)水蒸氣(qi)(qi)將會導致銅(tong)(tong)(tong)材的(de)(de)(de)晶間裂(lie)紋,從而引起(qi)真(zhen)(zhen)空(kong)品(pin)件泄漏,因此世(shi)界(jie)各國都(dou)(dou)專門(men)規(gui)定(ding)有無(wu)氧(yang)(yang)(yang)(yang)(yang)銅(tong)(tong)(tong)專門(men)品(pin)種(zhong),對氧(yang)(yang)(yang)(yang)(yang)含量作了嚴(yan)(yan)格(ge)規(gui)定(ding),我(wo)國零號(hao)、 1 號(hao)、 2 號(hao)無(wu)氧(yang)(yang)(yang)(yang)(yang)銅(tong)(tong)(tong)中氧(yang)(yang)(yang)(yang)(yang)含量分別(bie)(bie)規(gui)定(ding)為(wei)(wei) 5ppm 、 20ppm 、 30ppm ,而一般紫銅(tong)(tong)(tong)含氧(yang)(yang)(yang)(yang)(yang)量規(gui)定(ding)為(wei)(wei) 200ppm ,美國 ASTM 標(biao)準中電真(zhen)(zhen)空(kong)用無(wu)氧(yang)(yang)(yang)(yang)(yang)銅(tong)(tong)(tong)規(gui)定(ding)了 2 個(ge)牌號(hao),其氧(yang)(yang)(yang)(yang)(yang)含量分別(bie)(bie)為(wei)(wei) 5 ppm 和 10 ppm ,除此之外(wai),由(you)于在高(gao)(gao)真(zhen)(zhen)空(kong)的(de)(de)(de)條(tiao)件下(≤ 10 -8 /t ),銅(tong)(tong)(tong)中易蒸發(fa)(fa)的(de)(de)(de)元素(su)會破壞真(zhen)(zhen)空(kong)環境(jing),所以都(dou)(dou)要嚴(yan)(yan)格(ge)控制,特別(bie)(bie)是(shi) Zn 、 P 、 Mn 、 As 、 Sb 、 Bi 等(deng)元素(su),為(wei)(wei)確(que)保無(wu)氧(yang)(yang)(yang)(yang)(yang)銅(tong)(tong)(tong)的(de)(de)(de)高(gao)(gao)導電性(xing)能,要嚴(yan)(yan)格(ge)控制雜質含量,無(wu)氧(yang)(yang)(yang)(yang)(yang)銅(tong)(tong)(tong)中的(de)(de)(de)銅(tong)(tong)(tong)含量國家(jia)標(biao)準中規(gui)定(ding)零號(hao)、 1 號(hao)、 2 號(hao)無(wu)氧(yang)(yang)(yang)(yang)(yang)銅(tong)(tong)(tong)中銅(tong)(tong)(tong)含量分別(bie)(bie)規(gui)定(ding)為(wei)(wei) 99.99 、 99.97 、 99.95 ;無(wu)氧(yang)(yang)(yang)(yang)(yang)銅(tong)(tong)(tong)制品(pin)的(de)(de)(de)導電率(lv)應(ying)達到 100%IACS 。
