Abstract: Aluminum lead alloys are considered as bearing materials of 21st century because of its lubricant behavior of Pb phase component. In present work, Al-Pb alloy was produced by mixing powders of (Al-10 %Pb-4.5 %Cu weight) using ball milling process with periods (two, six and ten hours), fine grain size, homogenous distribution of powder were achieved and noticed that a reduction of particle sizes with increasing milling time. Various testing processes were used concluded compression strength test, microstructure test included optical microscope, scanning electron microscope (SEM), energy dispersive x-ray spectra scope (EDX), and x-ray diffraction (XRD). Results of this part showed that the mixing time of two hours gave the best condition as compared with other two mixing times.
