ABSTRACT:
Disclosed is a Cu--Pb alloy bearing and a producing method thereof. The Cu--Pb alloy bearing consists of a backing metal layer and a Cu--Pb bearing alloy layer which is bonded to the backing metal layer and whose matrix contains dispersed Pb-phase grains. Within an at least 30 .mu.m thick surface region of the Cu--Pb bearing alloy layer, the Pb-phase grains comprise at least one of In and Sn in an amount or a total amount of not less than 2 wt %, respectively, which are elements added into the Pb-phase grains by migration.
