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.
