In this work we1 successfully prepared aluminum-graphene composite (0.2 wt%) after 6 hrs of successful ball milling. The ball milling experiments were conducted between 2 and 6 hrs. The microstructal and spectroscopic comparison of aluminium-graphene composites were studied by evaluating properties by characterizing via XRD, FESEM, TEM, Micro Raman and microhardness. The second order disorder peak (2D) was found grow with milling time. In the Raman spectra intensity of 2D addresses about exfoliation take place of graphene in the composite. 0.2 wt% added graphene shows higher hardness than aluminium. Sintering of composites were done at 600 0C. Separation of stacking of carbon layers was confirmed from improvement of D peak in the ball milled samples. Sheet type structure of graphene was shown in TEM study. XRD confirms composite formation.
