In this study, Cu/Ag, Cu/Pb and Al/Pb binary metallic nanoparticles were synthesized by the electrical explosion of two twisted wires from immiscible elements (i.e., Cu-Ag, Cu-Pb and Al-Pb). The distribution of metallic components in the nanoparticles depended on the melting temperature, metal density, and degree of initial wire superheating. Different types of nanoparticles, such as nanoparticles with no separation between the metal phases, as well as core-shell and Janus nanoparticles were formed depending on the process parameters and the characteristics of the metals. Certain binary metallic nanoparticles were formed when the metal clusters were combined and formed during the initial stages of dispersing the two wires using a pulse of electrical current.
