Abstract

A high strength and wear resistant multi-element copper alloy is disclosed. The multi-element copper alloy consists of six principal elements and at least one additive element, in which the six principal elements are 97 to 98.5 atomic percent Cu, at most 0.1 atomic percent Al, 0.2 to 0.45 atomic percent Ni, 0.1 to 0.3 atomic percent Si, 0.15 to 0.45 atomic percent V, and 0 to 0.3 atomic percent Nb, and the at least one additive element is selected from a group consisting of Sn, Fe, Mn, Mg, C, P, and B. Moreover, experimental data have proved that, this multi-element copper alloy has a wear resistance greater than 475 m/mmafter being subjected to a homogenization process at 900 degrees Celsius for 6 hours and an age hardening process at 450 degrees Celsius for 50 hours.
