Abstract
Disclosed is a copper alloy sliding material having a metal structure wherein intermetallic compounds exist adjacently to Pb-phase islands and/or Bi-phase islands. Because intermetallic compounds exist between the matrix and the Pb phase and/or the Bi phase, the material can have improved anti-seizure property, since, under load or due to wear, the surface of the material has recessions at the soft Pb and/or Bi phase and the matrix with respect to the intermetallic compounds.
