Studies on aluminum-graphene nanocomposites mainly focus on improving thermomechanical properties, predicting suitable composites, and exploiting powder metallurgy to develop novel and cost-effective methods to fabricate Al-Gr nanocomposites. It is focused on developing these materials that can be used for influential solar collectors. A material's ability to conduct heat provides information about its purity and reliability. This investigation is supported to develop aluminum-graphene composites that can be used to improve the thermomechanical properties of solar collectors—thermal conductivity of Al-1.0 wt%. Gr is 249 W/mK, 129% higher than pure Al (123 W/mK). Aluminum density is maintained at 96.5% throughout the sintering process. The composites were evaluated using X-ray diffraction, FE-SEM, EDS, and Raman spectroscopy. This shows the strength of the sample. The sintering temperature of AlGr composites is estimated to be 611 degrees Celsius, which is ideal for composite fabrication. Temperature affected performance and thermal conductivity, increasing by 124% compared to the pure form. The thermal conductivity of graphene increases from 209 W/mK to 415 W/mK as the weight increases from 0.5 to 5.0.
