This study focuses on evaluating the surface roughness and mechanical properties of recycled metal matrix composite (MMC) materials developed from copper and aluminum 6061 alloys. The copper-based MMC was fabricated using 94% copper, 2% silicon carbide (SiC), 2% lead, and 1% fly ash, while the aluminum-based MMC consisted of 96% aluminum 6061, 2% SiC, 1% lead, and 1% fly ash. These composites were produced using the stir casting method to ensure uniform dispersion of reinforcements. The primary objective was to assess the potential of using recycled materials and industrial waste to enhance mechanical performance while promoting sustainable manufacturing practices. Surface roughness was analyzed using a stylus profilometer, and mechanical properties including tensile strength, hardness, and impact resistancewere tested according to ASTM standards. Results indicated that the inclusion of SiC and fly ash significantly improved hardness and wear resistance, while lead enhanced machinability. Aluminum-based MMCs demonstrated superior strength-to-weight ratios, whereas copper-based composites showed enhanced thermal conductivity and damping capacity. The findings suggest that recycled MMCs with tailored compositions offer a promising, eco-friendly alternative for structural and industrial applications
