專利摘要(英) |
---|
A high strength and wear resistant multi-element copper alloy is disclosed. The multi-element copper alloy comprises: 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. Experimental data reveal that, after being applied with an aging treatment under 450 degree Celsius for 50 hours, hardness and strength of the 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, measurement data have indicated that, this novel multi-element copper alloy exhibits better wear resistance superior to that of the conventional copper alloys. |
