專利摘要(中)
本發明主要揭示一種高強度耐磨耗多元銅合金，其組成包括：80〜90at％的Cu、0.1〜4at％的Al、6〜10at％的Ni、0.1〜3at％的Si、0.1〜2at％的V及/或Nb、以及0.1〜2at％的M。其中， M為選自於Zr、Cr、Ti、Sn、Fe、Mn、Mg、C、P、和B之中的至少一添加元素。實驗結果顯示，本發明之多元銅合金的多個樣品在以450℃的溫度進行時效處理50小時之後，其強度和硬度明顯升高，顯示出時效硬化之效，且在時效處理的過程中未有過時效軟化現象發生。並且，量測數據顯示，本發明之多元銅合金的多個樣品係相較習知的銅合金而顯示出更好的抗磨耗特性，因此本發明之多元銅合金係能夠取代習知的銅合金，從而被應用在各種要求具備優良抗磨耗特性之零件及/或構件的製造，例如：軸承、齒輪、活塞、連接器、導電軌、導線框架、繼電器、探針等。

專利摘要(英)
The present invention discloses a multi-element copper alloy with high strength and wear resistance, comprising: 80-90 atomic percent Cu, 0.1-4 atomic percent Al, 6-10 atomic percent Ni, 0.1-3 atomic percent Si, 0.1-2 atomic percent V and/or Nb, and 0.1-2 atomic percent M. In which, M represents at least one additive element that is selected from a group consisting of Zr, Cr, Ti, Sn, Fe, Mn, Mg, C, P, and B. Experimental data reveal that, after being applied with an aging treatment under 450 oC for 50 hours, hardness and strength of the novel multi-element copper alloy are both significantly enhanced because of age hardening, and softening due to overaging is not observed on the multi-element copper alloy. Moreover, measument data have indicated that, this novel multi-element copper alloy exhibits better wear resistance superior to that of the conventional copper alloy. Therefore, the multi-element copper alloy of the present invention has a significant potential for replacing the conventional copper alloy so as to be applied in manufacture of a variety of parts and/or components they are demended to possess excellent wear resistance, such as bearing, gear, piston, connector, conductor rail, lead frames, relay, and probe.
