Wear-resistant copper alloys and synchronizer rings for automobiles comprising the same |
摘要 |
A wear-resistant copper alloy which consists essentially of 56 to 65 wt. % of Cu, 28 to 32 wt. % of Zn, 3.5 to 5.5 wt. % of Al, 0.5 to 2.0 wt. % of Fe, 1.0 to 3.0 wt. % of Ni, 0.1 to 1.0 wt. % of Nb, and 0.4 to 1.5 wt. % of Ti, provided that Ti+Nb is equal to or greater than 0.7 wt. %. The alloy includes two discrete intermetallic compounds comprising Ti-Ni-Fe-Al and Nb-Fe-Al uniformly dispersed in a microstructure preferably including at least 50 volume % beta phase and limited alpha and gamma phases. A synchronizer ring made of the copper alloy is also provided.
