Summary:The article discusses computer modeling of the processes of casting resistance welding electrodes from the Cu-MMNCr composite material (copper metal matrix reinforced with nano-sized chromium) using the specialized professional program Pr°CAST. During the process of pouring the melt into a metal mold, the formation of a toroidal vortex was established, which does not allow nano-sized chromium particles to float to the surface of the melt. The process of formation of the solid phase during crystallization of the alloy leading to the formation of "heat spots" (Tfot Spots) at the final stage has been studied. The features of the formation of the macro- and microstructure and the elemental composition of the cast Cu-MMNCr composite material were studied. The results of the physical and mechanical properties of the cast Cu-MMNCr composite material are presented using the example of a product - a type D resistance welding electrode.
