Abstract :Effects of graphite insert ignore into journalissuearticles values(C); and silicon carbide particulates insert ignore into journalissuearticles values(SiCp); on the morphology, electrical and mechanical properties of C10200 copper insert ignore into journalissuearticles values(Cu); alloy have been investigated. The Cu alloy was reinforced with blended C and SiCp in varied wt. % by mould casting method to produce Cu-SiCp/C composites. Mechanical, electrical and microstructural properties of the hybrid Cu-SiCp/C composites were investigated. The developed composites exhibited acceptable electrical conductivity despite the addition of SiC/C particulates. The electrical conductivity of the Cu-SiCp/C composites is within the bound limits required in literature. The hybrid composite with 30/50/20 % formulation of Cu/SiCp/C exhibited the highest ultimate tensile strength of 90 N/mm2 and 92 N/mm2 for the 212 µm and 710 µm particle sizes respectively. The composite with 30/50/20 % formulation of Cu/SiCp/C exhibited hardness values of 28.7 HB and 30 HB for the 212 µm and 710 µm particle sizes respectively. The addition of SiCp/C appreciably increased the tensile strength and hardness of the composites.
