Manufacturing thin metal multi-layer composites and enhancing their mechanical properties are challenging tasks. In this study, a thin-layer metal composite (500 μm) consisting of brass/ST14/brass was fabricated using the cold rolling bonding (CRB) method. To optimize its mechanical characteristics, the composite was subsequently annealed at temperatures of 450°C, 600°C, and 750°C. The resulting samples were evaluated in terms of tensile strength, microhardness, formability, wear resistance, and surface morphology using SEM/BSE imaging. The results indicated that the sample annealed at 750°C exhibited the highest formability but the lowest tensile strength and wear resistance (i.e., greatest weight loss). In contrast, the unannealed sample showed the highest tensile strength and wear resistance, but the lowest formability. Among all treatments, annealing at 600°C provided the best overall balance of mechanical performance, demonstrating superior formability, tensile strength, and wear resistance. Therefore, it can be concluded that annealing at 600°C represents the optimal treatment for the brass/ST14/brass composite in this study.
