鎢銅合金是一種假合金,鎢與銅不互溶,充分結(jié)合了鎢的高導(dǎo)熱、高熔點、低熱膨脹系數(shù)與銅高導(dǎo)熱的特點。鎢與銅的比例可以任意調(diào)整,WxCuy,x+y=100。
Tungsten copper alloy is a pseudo alloy, tungsten and copper are not miscible, fully combined the high thermal conductivity, high melting point, low thermal expansion coefficient of tungsten and the high thermal conductivity characteristics of copper. The ratio of tungsten to copper can be adjusted,WxCuy, x+y=100.
我們的鎢銅合金可以做到幾乎完全致密、無缺陷、細(xì)晶組織,氦質(zhì)譜儀檢漏材料氣密性 < 5 x 10-9 Pa / m3.s,與國外產(chǎn)品相當(dāng)。應(yīng)用于微電子封裝熱沉、電阻焊電極、EDM電極、軍用發(fā)汗材料、高溫模具、高溫導(dǎo)軌等場合。
Our tungsten copper alloy can achieve almost complete compactness, no defects, fine grain structure, airtightness < 5 x 10-9 Pa / m3.s (with helium leak detection mass spectrometer), comparable to any first-class products in the world.
