The performance of an AA5051 alloy reinforced with novel silicon dioxide (SiO₂) was synthesized in this work and its tensile strength and percentage of elongation were compared with AA5051 alloy. Recycled AA5051 alloy was used as matrix materials and novel SiO₂ of particle size 60 nm are used as ceramic strengthening particles for synthesizing aluminum alloy nanocomposites using the stir casting method. Two groups of samples were prepared in terms of the control group (Recycled AA5051 Alloy) and experiment group (Recycled AA5051 Alloy + 2 wt.% SiO₂) nanocomposite. The outcomes of the studies were analyzed using t-test, and the significant level of the ultimate tensile strength and percentage of elongation properties of the as-cast recycled AA5051 alloy were compared with nanocomposites that had been synthesized. It was determined that there is a statistically significant difference between the two groups based on the significance value of p = 0.000 (2-tailed), which was achieved. This value is lower than the threshold of p < 0.05. According to the study’s limitations, it was found due to increased surface areas between the immixture it significantly increased the ultimate tensile strength (35.25%) and percentage of elongation (12%) in comparison with cast recycled AA5051 alloy.
