The present disclosure relates to rotor laminations having a first region and a second region, wherein the first region is larger than the second region and a first alloy is present in the first region and a second alloy is present in the second region. In accordance with the disclosure, the second alloy is soft-magnetic and has a higher magnetic permeability than the first alloy. The present disclosure further relates to an electric machine and an electrically powered vehicle. In addition, a method for producing the aforementioned rotor laminations is disclosed. For this purpose, a corresponding green part is printed in a stencil printing process and then sintered to form the rotor lamination.
