In the present investigation, the influence of nano-SiC on characterization of SiC/Cunano-composite was investigated. Electron microscope (SEM) was used for microstructure and morphology examinations. The erosion properties were investigated using pin on disc technique in oil environment.  The results indicated that the grain structure of the copper matrix was reduced with increasing SiCnano-particles. The erosion resistance increased by increasing nano-SiC content to 5, 10, 15 and 20 (vol. %) respectively. Furthermore, the study was also extended to examine the influence of SiC content on the nuclear properties using winXCom computer program (version 3.1).  It was found that there is no a significant variation in nuclear properties of Cu when the SiC is incorporated into the matrix at al l percentages.
