C19500-1/2H MSP1-1/2H銅合金電子沖壓

物理性能

(1) 優(yōu)異的物理、化學性能 純銅導(dǎo)電性、導(dǎo)熱性很好，銅合金的導(dǎo)電、導(dǎo)熱性也很好。銅及銅合金對大氣和水的抗蝕能力很高。銅是抗磁性物質(zhì)。

(2) 良好的加工性能 塑性很好，容易冷、熱成形；鑄造銅合金有很好的鑄造性能。

(3) 具有某些特殊機械性能 例如優(yōu)良的減摩性和耐磨性(如青銅及部分黃銅)，高的 性很限和疲勞很限(如鈹青銅等)。

(4) 色澤美觀 2、（紫銅）

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/cm2，熔點1083°C。純銅導(dǎo)電性很好，大量用于制造電線、電纜、電刷等；導(dǎo)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；塑性很好，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。?
