Copper-based sliding member containing 1.5 to 10.0 mass% of Sn, and remaining being Cu and impurities

A sliding member of the present invention comprises a bearing alloy made of Cu-Sn alloy. The Cu-Sn alloy contains 1.5 to 10.0 mass% of Sn and remaining is Cu and impurities. Observed from a profile perpendicular to a sliding surface, there exist a distribution of high-tin concentration areas. The Sn...

Beschreibung
Zusammenfassung:	A sliding member of the present invention comprises a bearing alloy made of Cu-Sn alloy. The Cu-Sn alloy contains 1.5 to 10.0 mass% of Sn and remaining is Cu and impurities. Observed from a profile perpendicular to a sliding surface, there exist a distribution of high-tin concentration areas. The Sn concentration in the high-tin concentration areas is 1.1 times more than the average Sn concentration of the Cu-Sn alloy, and the area of the high-tin concentration areas is more than 500[mu]m2. The number of the high-tin concentration areas is 5 to 93 per 1 mm2.
