Aluminium-based Metal Matrix Composites (MMCs) have received increasing attention in recent decades as engineering materials. The introduction of a ceramic material into a metal matrix produces a composite material that results in an attractive combination of physical and mechanical properties which cannot be obtained with monolithic alloys [1]. The aluminum based composites are increasingly being used in the transport, aerospace, marine, automobile and mineral processing industries. The various reinforcements that have been tried out to develop aluminium matrix composites(AMCs) are graphite, silicon carbide, titanium carbide, tungsten, boron, Al203, fly-ash, Zr, TiB2 Addition of hard reinforcements such as silicon carbide, alumina, and titanium carbide improves hardness, strength and wear resistance of the composites [1, 2-4]. The ceramic nano particles reinforced aluminum composites are termed as new generation material and these can be tailored and engineered with specific required properties for specific application requirements. The metal matrix composites are cost efficient and they are also known for excellent heat and wear resistance applications [3]. In this paper it is aimed to present the experimental results of the studies conducted regarding hardness and Density and tensile strength of Al7068-Graphite nano particulates. The composites are prepared using the liquid metallurgy technique in which 3-9 wt.% age of particulates were dispersed in the base matrix in steps of 3. The obtained cast composites of Al7068- nano Graphite and the castings of the base alloys were carefully machined to prepare the test specimens for density, hardness and as well as mechanical studies as per ASTM standards.
