Abstract
Copper matrix composites (CMC) with reinforcement of Graphite (Gr) and Nano Zirconium Oxide (ZrO2) is found more prominent composite material for various application such as automotive, aerospace, marine industry due to its elemental mechanical properties. In this paper, the mechanical properties of 90% Cu-10% Sn alloy were compared with different composition of nano ZrO2 and Graphite particulates. The mechanical properties like hardness, tensile and microstructural analysis was carried with SEM and EDS to observe homogeneous distribution of reinforcement particles in the matrix composites. After test, it was found that, Cu-Sn alloy with Gr and ZrO2 composite mixture of ultimate tensile strength and yield strength was higher and hardness of the copper alloy matrix can be improved by addition of nano ZrO2 particulates.
