Abstract This study introduces an innovative approach to fabricate aluminum matrix composites strengthened with biochar, derived from renewable biomass sources. A systematic investigation of varying biochar weight percentages (0, 2.5, 5, 7.5, and 10 wt%) reveals substantial improvements in mechanical properties corrosion resistance. Mechanical assessments, including compressive strength hardness, demonstrate a significant enhancement incorporation. In this study, it was discovered that the composite 7.5 wt% exhibits optimal balance, displaying 8.83% increase 15.15% rise hardness compared base matrix. The further evaluates behavior through electrochemical analyses immersion tests 3.5% NaCl corrosive environments, highlighting superior resistance biochar-reinforced composites. Corrosion rates decrease by 73% for 24hrs time, affirming its protective barrier against agents. research provides quantitative insights into tailoring reinforcement, offering promising avenue sustainable material development. resulting materials exhibit not only but also reduction rates, valuable uses industries need strong, eco-friendly solutions.
