The goal of this research is to evaluate the electrical, dry sliding wear and corrosion behaviour of copper-zinc alloy reinforced with Ni and Si through Powder Metallurgy (P/M) technique. Six different wt. % of novel copper-zinc alloy are considered for this research study namely 90Cu-10Zn, 88.16Cu-10Zn-1.5Ni-0.34Si, 85Cu-15Zn, 83.16Cu-15Zn-1.5Ni-0.34Si, 80Cu-20Zn and 78.16Cu-20Zn-1.5Ni-0.34Si. The fabricated composites were characterized by using Scanning Electron Microscope (SEM) with Energy Dispersive Spectroscopy (EDS) line mapping. The electrical, wear and corrosion behaviour of the fabricated composites was assessed. The hardness of the fabricated composites was evaluated using Vickers Hardness Tester. The electrical conductivity was assessed using four-point probe tester. The result shows a significant improvement on electrical and tribological properties by increasing the wt.% of Zn, Ni and Si led of the composites. The research results concludes that 78.16Cu-20Zn-1.5Ni-0.34Si composite possessed better hardness about 287 HV and the electrical conductivity about 121% IACS. The investigation result shows that Zn acts as a vital role to enhance the properties in all aspects. Also, the experimentation results portrays that Cu-20Zn-1.5Ni-0.34Si composite possessed better specific wear rate and coefficient of friction such as 1.85 * 10^-5 mm³/N-m and 0.29 respectively
