Abstract
The invention relates to a hybrid pin () for connecting a piston for an internal combustion engine to a piston rod, the hybrid pin () consisting of a sleeve () made of steel and consisting of a core () which is pressed into the sleeve () and which is made of a lightweight metal alloy that can be cold-formed. The inner surface of the sleeve () has a profile, whereby an elastic elongation of the core () in the axial direction after the core () is pressed into the sleeve () is prevented to such an extent that the sleeve () is longer than the core () at both ends of the hybrid pin ().
