</p> <p> 其具有機械強度高、易加工成型、導電能力高等優(yōu)點。其成本低于金、銀等導電能力更高的貴金屬；導電能力高于鋁、鋼等成本更低的金屬。且目前地球探明儲量較多，屬于非常適宜的可以純銅是玫瑰紅色金屬，表面形成氧化銅膜后呈紫色，故工業(yè)純銅常稱紫銅或電解銅。密度為8-9g/cm3，熔點1083°C。純銅導電性很好，大量用于制造電線、電纜、電刷等;導熱性好，常用來制造須防磁性干擾的磁學儀器、儀表，如羅盤、航空儀表等;塑性極好，易于熱壓和冷壓力加工，可制成管、棒、線、條、帶、板、箔等銅材。純銅產(chǎn)品有冶煉品及加工品兩種。大規(guī)模應該的良好導體。 </p><p> 無氧銅是不含氧也不含任何脫氧劑殘留物的純銅。但實際上還是含有非常微量氧和一些雜質。按標準規(guī)定，氧的含量不大于0.03%，雜質總含量不大于0.05%，銅的純度大于99.95%。 </p> <p> <br /> </p> <p> 根據(jù)含氧量和雜質含量，無氧銅又分為一號和二號無氧銅。一號無氧銅純度達到99.97%，氧含量不大于0.003%，雜質總含量不大于0.03%;二號無氧銅純度達到99.95%，氧含量不大于0.003%，雜質總含量不大于0.05%。 </p> <p> <br /> </p> <p> 無氧銅無氫脆現(xiàn)象，導電率高，加工性能和焊接性能、耐蝕性能和低溫性能均好。 </p> <p> <br />
