COPPER-BASE BEARING MATERIAL AND SLIDING BEARING FOR INTERNAL COMBUSTION ENGINE

摘要

A copper-base material for sliding bearings, which is highly resistant to burning through containing no Pb. To make its overlay coating thin, the material contains 0.1 to 2 % Ag, 1 to 10 % Sn and the balance consisting of Cu and unavoidable impurities. In this copper alloy, Ag and Sn do not substantially form the second phase but are completely or substantially in a solid solution state.
