Abstract

A metal casting has a metal casting base body into which at least one metal insert body (1) is cast. The metal insert body has anti-twisting part-contours and is connected to the metal casting base body in a positively locking manner by the casting-in. To simplify the production of a stable metal casting, the metal insert body (1) has an elongate shape with a longitudinal axis and an outer mold contour with an unround cross section interrupted in the longitudinal direction by annular grooves (11-13) that fix the cast-in metal insert body (1) in the axial direction.
