鍍錫紫銅管排是銅排中的一種，銅排是一種大電流1產(chǎn)品，適用于高低壓電器、開關(guān)觸頭、配電設(shè)備、母線槽等電器工程。由于錫在大氣中非常穩(wěn)定，稱之為“耐候性好”。鍍錫可以有效防止銅排受潮生銅綠、也可以阻止銅氧化/硫化變黑影響電接觸性。 </p> <p> 紫銅排具有較強(qiáng)的導(dǎo)電性、導(dǎo)熱性、延展性和抗腐蝕性，他也可以在多種環(huán)境下進(jìn)行使用。不過紫銅排在生產(chǎn)的時(shí)候微量雜質(zhì)對(duì)銅的性能都會(huì)起到一定的影響，其中氧對(duì)銅的影響比較大，會(huì)使銅的焊接性得到損傷。紫銅排的手工電弧焊，由于焊接質(zhì)量不太穩(wěn)定，焊縫含氫量較高，容易引發(fā)氣孔、裂紋等缺點(diǎn)問題；同時(shí)操作技術(shù)要求高、焊接條件差等，一般也不會(huì)太實(shí)用。

的高溫下，在氫氣中進(jìn)行釬焊，此時(shí)氫氣與銅中的氧會(huì)發(fā)生 Cu 2 O+H 2 → Cu+H 2 O 反應(yīng)，所產(chǎn)生的水蒸氣將會(huì)導(dǎo)致銅材的晶間裂紋，從而引起真空品件泄漏，因此世界各國都專門規(guī)定有無氧銅專門品種，對(duì)氧含量作了嚴(yán)格規(guī)定，我國零號(hào)、 1 號(hào)、 2 號(hào)無氧銅中氧含量分別規(guī)定為 5ppm 、 20ppm 、 30ppm ，而一般紫銅含氧量規(guī)定為 200ppm ，美國 ASTM 標(biāo)準(zhǔn)中電真空用無氧銅規(guī)定了 2 個(gè)牌號(hào)，其氧含量分別為 5 ppm 和 10 ppm ，除此之外，由于在高真空的條件下(≤ 10 -8 /t )，銅中易蒸發(fā)的元素會(huì)破壞真空環(huán)境，所以都要嚴(yán)格控制，特別是 Zn 、 P 、 Mn 、 As 、 Sb 、 Bi 等元素，為確保無氧銅的高導(dǎo)電性能，要嚴(yán)格控制雜質(zhì)含量，無氧銅中的銅含量國家標(biāo)準(zhǔn)中規(guī)定零號(hào)、 1 號(hào)、 2 號(hào)無氧銅中銅含量分別規(guī)定為 99.99 、 99.97 、 99.95 ;無氧銅制品的導(dǎo)電率應(yīng)達(dá)到 **IACS 。 </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
