[origin: WO8707308A2] A process for making a composite bearing material comprising a steel backed, prealloyed, lead-bronze sintered powder metal matrix whereby the first sinter step includes induction heating the prealloyed powder and steel backing to about 650 DEG C and thereafter sintering the same at temperatures of about 850 DEG C in a second sintering furnace. A composite bearing material made by the same process and comprising a lead particle size averaging less than about 8 microns and having no lead islands larger than about 44 microns.
