Method of obtaining of cast composite materials (CCM) on the basis of aluminum reinforced by σ- phase (FeCr) is proposed. The wear rate of specimens from CCM is depended on the height of casting, which these specimens were cut out from. The average size of particles FeCr 27.5-35.5 μm and their quantity 184–263 pieces/mm2 make the greatest positive influence on wear rate of CCM under dry friction.
