The failures of material performance in industry are due to structural, corrosion and wear dilapidation in service. This study attempts to develop AA6061 with rice husk ash and clay hybrid to address this phenomenon for application in cooling tower fan blade. This study also targets at developing sustainable and long-lasting hybrid of aluminium biodegradable composites through metallurgical stir casting techniques. Corrosion properties were examined using Potentiostat Galvanostat (PGStat 101) with Nova software acquisition while pin-on-disc wear machine was used to analyse the wear propagation of the composites. The microstructure, chemical composition and quantification were examined with SEM/EDS. It was established that the reinforcement improved corrosion susceptibility of the composites in 0.75 M H 2 SO 4 solution. The coefficient of friction and the wear resistance of the hybrid composites were better than the as-received sample. Furthermore, AA6061/8% rice husk ash + clay at 75 µm possesses rod-like pattern and unique structure grain crystal.
