This means, the weight of the machine component produced from these materials can be reduced. In this study, the mold casting method was used in the production of Al 2024 matrix composite materials. In sample production, 50% MgO and 50% MWCNT are mixed by weight and added to the matrix material in the ratio of 0.2%-0.5%-1%-2%. The hardness and wear behaviors of Al 2024 composites with MgO / MWCNT additive were investigated using Rockwell tester and a ball-on-disc wear tester. The effects of composite materials on the wear properties have been investigated by determining the wear weight loss. 5N load and 250 m distance were chosen as the wear test parameters and percent wear amounts of the samples were examined. It was observed that hardness values of samples increased, and the wear percentage of specimens decreased with the addition of reinforcement. The best ratio for the composite design is the mixing of 50 wt.% + MgO 50 wt.% CNT with 1 wt.%.
