Abstract
A method for powder-metallurgically manufacturing a rotational body, including compacting a first starting body is compacted from a metal powder; forming a second starting body from metal, separately from the first starting body; placing the starting bodies against each other in axial contact via end faces in relation to a longitudinal axis of the rotational body; and permanently and firmly sintered the first starting body and the second starting body to each other by collective sintering. The first starting body is compacted from an aluminum-based powder, the second starting body is formed from an aluminum material, and the starting bodies are sintered to each other at their respective end faces.
