The study explored the effects of niobium (Nd) and tin (Sn) contents on the tensile behavior and electrical conductivity of Cu-30wt%Zn alloys. The brass was incorporated with varying concentrations of niobium and tin (0.1- 0.5wt% and 1.0-5.0wt% at 0.1 and 1.0 intervals respectively) and fabricated using a stir-casting technique. The Tensile strength, electrical conductivity, and resistivity were examined. The microstructures of the cast alloys were analyzed using a Scanning electron microscope (SEM), and Energy dispersive spectroscope (EDS). Results showed that the additions of niobium and tin refined and modified the structure of the alloy resulting in improvements in tensile strength, and electrical conductivity of the alloy, with 3wt% niobium and 5wt% tin recording the maximum tensile behavior performances and 0.1wt% niobium and tin exhibited the highest electrical conductivity.
