Abstract: The present invention relates to processes for producing cut metal bodies, comprising the providing of metal bodies, the subsequent applying of metal-containing powders, a thermal treatment for alloy formation and the splitting of the alloyed metal bodies using a process selected from the group: severing, machining with geometrically defined cutting edge and waterjet cutting. The temperature profile in the thermal treatment allows alloy formation to take place at the contact surface between metal body and metal-containing powder, but at the same time leaving unalloyed regions in the interior of the metal body. The present invention further relates to processes in which the splitting of the alloyed metal bodies is followed by a treatment with leaching agent so as to obtain catalytically active metal bodies. The use of the inventive splitting process for producing the cut metal bodies affords particularly active catalysts.
