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.

1. A metal casting comprising: at least one elongate metal insert body with a longitudinal axis and a plurality of axially spaced anti-twisting part-contours defined by an outer mold contour and spaced apart from one another in a direction parallel to the longitudinal axis, each of the axially spaced anti-twisting part-contours having identical non-cylindrical cross section with at least three outwardly convex curved surfaces meeting at curved or linear corners extending parallel to the longitudinal axis, the outer mold contour being interrupted by annular grooves at longitudinally spaced positions and disposed respectively between the axially spaced anti-twisting part-contours, a functional opening extending into one longitudinal end of the metal insert body, the metal insert body having a closed longitudinal end opposite the longitudinal end that has the functional opening; anda metal casting base body defining a unitary matrix of metal surrounding at least parts of the outer mold contour and the annular grooves of the metal insert body in a positively locking manner, while leaving the functional opening exposed, the metal casting base body covering only an outer peripheral region of the closed longitudinal end of the metal insert body with a central area of the closed longitudinal end being exposed. 2. The metal casting of claim 1, wherein the annular grooves have a substantially rectangular cross section. 3. The metal casting of claim 2, wherein the annular grooves are machined with a removal of material. 4. The metal casting of claim 1, wherein the metal insert body with the outer mold contour and the annular grooves is cast completely into the metal casting base body. 5. The metal casting of claim 1, characterized in that the functional opening comprises a recessed counterbore for positioning the metal insert body before casting-in, the counterbore being cross-sectionally larger than the functional opening and being exposed from the metal casting base body at the longitudinal end of the metal insert body. 6. The metal casting of claim 1, wherein the metal casting base body is formed from light metal. 7. The metal casting of claim 1, wherein the metal insert body comprises at least one of an aluminum material, a steel material and titanium. 8. The metal casting of claim 1, wherein the metal insert body is formed from a bar material as an extruded profile, a rolled profile or an impact-extruded part. 9. The metal casting of claim 1, wherein the metal insert body is rolled, drawn, forged or produced by impact extrusion. 10. The metal casting of claim 1, wherein the outer mold contour has a rough exterior. 11. The metal casting of claim 1, wherein an end face of the metal insert body is formed to prevent injection of metal into the metal insert body. 12. The metal casting of claim 1, wherein the metal casting base body includes a sleeve surrounding the metal insert body and at least one substantially plate-shaped structural part unitary with the sleeve and extending from the sleeve at a position adjacent the longitudinal end of the metal insert body that has the functional opening. 13. The metal casting of claim 12, wherein the substantially plate-shaped structural part is substantially perpendicular to the longitudinal axis of the metal insert body. 14. The metal casting of claim 12, wherein the substantially plate-shaped structural part is substantially parallel to the longitudinal axis of the metal insert body. 15. A metal product comprising: at least one elongate metal insert body with a longitudinal axis and opposite first and second longitudinal ends spaced apart along the longitudinal axis, an outer mold contour between the first and second longitudinal ends, the outer mold contour having a plurality of axially spaced anti-twisting part-contours, each of the axially spaced anti-twisting part-contours having identical non-cylindrical cross sections, the outer mold contour being interrupted by annular grooves at longitudinally spaced positions and disposed respectively between the axially spaced anti-twisting part-contours, a functional opening extending into the first longitudinal end of the metal insert body and the second longitudinal end of the metal insert body being closed, the functional opening having a counterbore at the first longitudinal end of the metal insert body; anda metal casting base body defining a unitary matrix of metal forming a sleeve surrounding at least parts of the outer mold contour and the annular grooves of the metal insert body in a positively locking manner, while leaving exposed the functional opening and a central portion of the second longitudinal end of the metal insert body inward of the outer mold contour, the metal casting base body further including at least one plate-shaped structural part unitary with the sleeve and extending from the sleeve at least at a position adjacent the longitudinal end of the metal insert body that has the functional opening. 16. The metal product of claim 15, wherein the plate-shaped structural part is substantially perpendicular to the longitudinal axis of the metal insert body. 17. The metal product of claim 15, wherein the plate-shaped structural part is substantially parallel to the longitudinal axis of the metal insert body.
