Al-Cu-Mg alloy is a superior corrosion and resistant alloys within the aluminum alloys family. Notwithstanding its commendable corrosion resistance, it has inadequate mechanical qualities, resulting in suboptimal expansion across diverse applications. In this work, samples of (Al-Cu-Mg) alloy reinforced with titanium boride (TiB2) nanoparticles with a length of (90 mm) and a diameter of (10 mm) were synthesis using powder metallurgy technique and powder pressing method. TiB2 nanoparticles were selected with a weight percentage of (1, 3, 5%). The X-ray diffraction, surface morphology, and mechanical properties investigated. The base and composite materials were prepared by powder pressing method using a 10-ton press. Tensile strength, ductility, hardness, and microscopic examinations were performed on the composite, revealing that an increase in the particle size ratio of TiB2 correlates with enhanced tensile strength, reduced ductility, increased hardness, and a uniform distribution of particles relative to the base matrix (Al-Cu-Mg).to the base matrix (Al-Cu-Mg)
