Recently, composite materials are among the most prospective substances. The improved characteristics were possessed by Metal matrix composites (MMCs) but which is low in comparison to plain composites. Due to low cost and density, nowadays composite materials most trendy one. Therefore, composite materials reinforced with fly ash particulate of bagasse fly ash will probably overcome the barrier of expense in the applications of small motor and automobile industry. In the current study, a technique of stir casting has been utilized to prepare reinforcement of AL6061 alloy with 5 wt% to 25 wt% of fly ash particulate matter of bagasse fly ash. In this study, the identification of phase and characterization of structures was performed with the help of analysis of diffraction in the X-ray on the fly ash particulate matter of bagasse. The analysis of microstructure was performed with the help of optical microscopy and Scanning electron microscopy. The test like pitting corrosion, compression and hardness have been performed on composite materials and light metal. The analysis of SEM demonstrates that in the matrix stage, there is a homogeneous distribution of fly ash particulates of bagasse and also excellent adhesion is existing among reinforcement and matrix. The hardness, pitting corrosion and compressive strength were improved, and the density of the composite materials was decreased when there is an improvement in the number of fly ash particulates of bagasse. The enhanced pitting corrosion of reinforcement of aluminum alloy with fly ash particulates of bagasse is related to the initiation of the nobler second stage of fly ash particulate matter.
