である。From the results shown in Table 1, Cu-based sintered alloys 1 to 1 of the present invention
No. 30 has a coefficient of friction H equivalent to that of conventional Cu-based sintered alloys, which indicates that they have excellent synchronization characteristics with respect to the mating member, and also have superior durability compared to conventional Cu-based sintered alloys. However, as seen in Comparative CuM sintered alloys 1 to 7, if the content of any of the constituent components falls outside the scope of the present invention, the wear resistance is poor. It is clear that at least one of the properties of toughness, strength, and toughness becomes inferior.
