Hybrid aluminum composites are frequently used in industrial applications because of their attractive mechanical and tribological properties to weight ratio, such as hardness, strength, and wear resistance. This work investigated the mechanical properties, microstructure, density, and wear behavior of Al-6061 matrix reinforced with different percentages (2 and 4 Wt.% for each Al2O3, SiO2, SiC, and TiO2) and (2 and 4 Wt.% for each Al2O3, TiO2, and SiC, SiO2) hybrid composites at 50 μm average size using the powder metallurgy technique. The process of creating a component in net or nearly net shape is known as powder metallurgy. Due to its benefits, including great dimensional control and the avoidance of intermediate machining operations, P/M is one of the fastest-expanding pathways in many industrial applications. According to the results, the optimum hardness and density were 95 HV and 3.1 g/cm3, respectively, for the hybrid composite (Al- 2SiC 2SiO2) after the sintering operation. The highest hardness was (95HV) at the addition hybrid composite (Al- 2SiC 2SiO2). Microstructural characterization using optical microscopy shows that the hybrid composite (Al-2%SiC 2%SiO2) was the best. The SEM photographs of the worn surface of the Al-2%SiC/2%SiO2 hybrid composite exhibited the least wear losses and grooves. The lowest wear rate was (13*10ˉ6) at the addition of hybrid composite (Al- 2SiC 2SiO2) at load (5N).
