This project aims to compare the compression strength of the recycled AA7075 alloy metal matrix composite with and without reinforcing novel titanium dioxide (TiO₂). Recycled AA7075 alloys constituted the matrix, whereas novel TiO₂ with particle sizes less than 50 nm was used as reinforcement. It was squeeze cast at 720°C and 500 rpm to provide homogeneous reinforcement distribution in matrix materials. There are two types of recycled AA7075 alloy nanocomposite (Experiment 1 and control group 1). With the aid of the SPSS (Statistical Package for the Social Sciences) v26 statistical analysis program, the compressive strength of the innovative silicon dioxide reinforced recycled AA7075 alloy was examined and contrasted with the material used in the control group. It was noted that p = 0.000 (2-tailed) was observed, which is less than (p < 0.05) exemplifying that there was statistically noteworthy variance between the investigational and controller group. When compared to the base alloy, the impact strength of innovative TiO₂ -reinforced recycled AA7075 alloy composites was found to be 69.89% higher than that of the base alloy.
