Described is a molded part made of light metal, in particular a crankcase for an internal combustion engine, comprising holes (5) for receiving fastening screws (6) with the help of which compressive strains can be exerted on the molded body in a light metal area. In order to create advantageous constructional conditions, it is proposed that at least one open-pored sintered body (7) is cast in the light metal area exposed to compressive strains with infiltration of the light metal at least in the pores of a surface layer; and that the sintered body (7) having a lower coefficient of thermal expansion than the light metal has a strength at least corresponding with the strength of the light area when combined with the infiltrated light metal.
