In this present study, LM25 /Coco fiber ash (CFA) metal matrix composites (MMCs) were fabricated by Stir casting method, Taguchi method and ANOVA Techniques used for different weight fractions of reinforcement were used to fabricate the composites. Scanning electron microscope (SEM) equipped with energy dispersive X-ray analyzer (XRD) is used for micro structural characterization. The properties like ultimate tensile strength, compressive strength and micro hardness were investigated. The results of micro hardness revealed higher hardness of the matrix material in the immediate vicinity of Coco fiber ash particle. The addition of Coco fiber ash particle reduces the density of composite while increasing some of their mechanical properties.
