In recent years, aluminum alloy-based matrix composites (MMCs) are gaining importance in several aerospace and automobile applications. Aluminum has been used as matrix material owing to its excellent mechanical properties coupled with good formability. Addition of SiC as reinforcement in aluminum system improves mechanical properties of composites. In the present investigation, Al-SiC composite was prepared by powder metallurgy route. Powder metallurgy homogeneously distributes the reinforcement in the matrix with no internal reaction and with less porosity. SiC particles containing different weight fractions (10, 15 and 18 %) and mesh size (320) are used as reinforcement. Though Al-SiC possesses superior mechanical properties, the high abrasiveness of the SiC particles obstacle the wide application. Al-SiC composite has the widest application in the aerospace industry due to high hardness and light weight material. After the development of material, specimens were tested under micro-hardness, density and scanning electron microscopic (SEM).
