The high cost and negative environmental impact of traditionally made aluminium metal matrix composites (AMMC) need their replacement with eco-friendly materials with improved mechanical characteristics. The repurposing of agricultural waste in innovative materials is critical to achieving a sustainable society. This study utilized AA6061/chitosan at sieve size of 90¸tm created via modified stir casting at weight proportions of 3, 6, 9, and 12 wt. %. The produced composites reached a maximum hardness of 60.2 HRB at 9wt. % chitosan, comparable to a 2.36 % improvement in AA6061 hardness, 57.4 HRB. Similarly, tensile strength increased with increasing chitosan particles, from 83.07MPa for the unreinforced alloy to a maximum of 114.92MPa for 12 wt. % AA6061 reinforcement with chitosan. The samples’ XRD revealed clear evidence of Hydroxyapatite, Ca10(PO4)6(OH)2, a component of teeth and bones that provides strength. The corrosion characteristics findings reveal that AA6061+9 wt. % chitosan has the lowest corrosion rate of all the samples. In addition, the microstructure of AA6061 with chitosan strains of reinforcement was observed in the AA6061/3wt. % SEM, eventually filling grain boundaries of the metal with increasing reinforcements to provide evenly distributed fibrous links connecting AA6061 grain structure at 6wt. % and 9wt. % reinforcement in the micrograph
