<br/><br/> This study presents Al-Ni composite reinforced by GNPs and SiC with different volume fraction by powder metallurgy technique. Besides, the obtained composites were investigated with different tests such as microstructure, relative density, hardness, wear, compression, and coefficient of thermal expansion tests. The results showed that by addition of SiC and increasing its percentage, the physical and mechanical properties are increased by increasing SiC up to 15 wt% then deceased. Also XRD showed the formation of new phases formed Al3Ni, Ni₃C
