Aluminum 6061-based metal-matrix composites (MMCs) have received considerable attention for automobile and industrial sector applications because of the low density and high stiffness. Improvement in fuel consumption rate requires a reduction in vehicle weight. Research and development for materials substitution in the braking system, from the conventional cast into aluminum, has been undertaken. A composite material is a material system composed of a suitably arranged mixture or combination of two or more Nano, micro, or macro constituents with an interface separating them that differ in form and chemical composition and are essentially insoluble in each other. They have characteristics like high strength to weight ratio, hardness and wear resistance. In the present investigation, an AI6061 alloy is using as the matrix and ceramic as the reinforcement. The composite is fabricated using stir casting technique. Aluminum composites are a new generation of metal matrix composites that have potential of satisfying the recent demands of advanced engineering applications. These demands are met due to improving mechanical properties, amenability to conventional processing technique and possibility of reducing production cost of aluminum composites. The casting components are machining to specimen dimensions and are subjecting to various material testing and finding the mechanical properties. In different weight fraction of ceramic reinforced materials. By conducting various materials testing like scanning Electron Microscopy (SEM). Pin-on-disc test, Universal Testing Machine (UTM), X-ray diffraction. The results will show as The best results have been obtained at Track Dia =55, Load=10N, Speed=600rpm, and reinforcement=7% by wt. proportion of Sic as a reinforcement. The formation of cluster is observed in when 3% siC+graptie` used as reinforcement in the Al6061 matrix which are observed in SEM photograph. The hardness value is higher, due to 7% of SiC+Graphite as reinforcement, with homogenous distribution of particles as shown in EDS report. The surface roughness is more for the specimen having 3% reinforcement. From the UTM test, If reveals that 7 %(sic+graphite)would have good strength of tensile
