Abstract
In a synchronizer ring that is a part of an automobile transmission, a ring body is made of an iron material and a sliding member is made of a wear-resistant copper alloy having the following chemical components, matrix and rigidity, characterized in that the ring body and sliding member are bonded to each other by way of hot working. (1) a wear-resistant copper alloy containing Zn of 22 to 45 wt %, at least one kind of metal elements of 0.1 to 15 wt % which are selected from a metal element group of Al, Mn, Fe, Pb, Ni, Be, Si, Co, Cr, Ti, Nb, V, Zr, Mo, Sn, Bi, B etc. and the remnant composed of Cu and impurities. (2) The wear-resistant copper alloy has a matrix of .alpha. phase+.beta. phase, .beta. phase alone or .beta. phase+.gamma. phase. (3) HRB (Hardness Rockwell B) value is more than 80. As a result, it is possible to provide a high performance composite-material synchronizer ring capable of sufficiently withstanding a high load since it comprises a ring body made of an iron material which is superior in rigidity and strength and a wear-resistant copper alloy material bonded to the sliding surface side of the ring body by way of hot working such as hot forging and the like.
