The invention discloses a preparation method of a metal-based graphene composite material and a metal-based graphene electrical contact, and the preparation method comprises the following steps: S1, mixing graphene slurry and metal powder to form mixed slurry; and S2, forming the metal-based graphene composite material from the mixed slurry in an oxygen-free environment at 980-1050 DEG C through a chemical vapor deposition method. The metal-based graphene electric contact is prepared from a metal-based graphene composite material. The preparation process is simple, the prepared metal-based graphene electric contact material is low in cost, the prepared metal-based graphene composite material improves the performance of an original metal material, and an electric contact prepared from the material has excellent electric conductivity and thermal conductivity, has the characteristics of oxidation resistance and corrosion resistance, and has a good application prospect. And the excellent performance of the electr
