Abstract This study focuses on the fabrication of aluminum treated with nanocomposites made of aluminum and NbB 2 and ZrB 2 nanoparticles. These nanoparticles were obtained by fragmentation in a ball mill and then mechanically alloyed with pure aluminum powder to form Al/NbB 2 and Al/ZrB 2 nanocomposite pellets, which were then sintered at 260°C for half an hour to improve the metal/borides interface. The sintered nanocomposites were incorporated into molten pure aluminum to produce 1-mm-diameter wires after cold forming. The wire specimens were mechanically characterized and their electrical resistivity was measured. Our results demonstrated the feasibility of improving the mechanical properties of aluminum wires with the addition of nanocomposites without significantly affecting their electrical conductivity.
