A nano-composite is composed of one or more chemically distinct inert phases, and its structural and distinctive qualities are superior to those of the constituent parts acting separately. This review paper focuses on enhancing the mechanical properties of composites through the integration of micro- and nanoparticles into an aluminum matrix. The article provides an overview of Aluminum Alloy (7075) matrix composites. Due to their exceptional strength, metallic matrix composites made from aluminum alloys find frequent applications in aerospace, automotive, defense, marine, and industrial fields. Due to their ease of processing and heat-treatability, heat-treatable alloys such as AA2024, AA6061, and AA7075 have garnered the interest of numerous researchers. This is primarily because these alloys can be readily modified to exhibit properties that are suitable for specific applications. The article discusses the mechanical properties of Aluminum Metal Matrix Composites (MMCs) reinforced with one or more particulates, such as aluminum oxide (Al2O3), zirconium oxide (ZrO2), titanium oxide (TiO2), silicon carbide (SiC), graphite, and titanium diboride (TiB2), among others. AA7075 exhibits remarkable ultimate tensile strength, good corrosion and wear resistance, and enhanced thermal stability.
