Composite plays a vital role in material science especially in the field of aerospace, marine, automobile, military and structural applications. It consists of two or more physically and chemically distinct phases. The composite has hybrid characteristics than those of individual components. Metal Matrix Composites (MMC) is those which are based on metals as matrix. Usually the reinforcing component is distributed in the continuous or matrix component. MMC focuses mainly on a relatively high strength and wear resistance applications. Aluminium Matrix Composites (AMC) is one in which Aluminium is the matrix and it has the property of high strength to weight ratio. The purpose of the work is to process and to determine the mechanical properties of AA2219-TiCp.Aluminum Matrix reinforced with TiCp composite was produced using modified stir casting process. Five different weight % of TiCp addition were performed without defects. The weight fractions used were 3%, 4%, 5%, 6%, 7%. The colour optical graphs, XRD, EDX analysis revealed the presence of TiC in the cast AMC. Tensile test, micro-hardness test shows the clear indication of considerable increase in Ultimate Tensile Strength(UTS) when the percentage of TiCp addition was increased.
