A method for producing a semifinished part (20) for an implant, in particular for an intraluminal endoprosthesis, which comprises the following steps: a) providing a first sleeve (11) from a first metallic material and at least one second sleeve (12, 13) from a second metallic material, b) arranging the first sleeve (11) and the at least one second sleeve (12, 13) into one another in such a manner that the sleeve combination (10) forms at least a press fit between said sleeves, and c) forming the sleeve combination (10) at an increased temperature by means of extrusion. The invention further includes a method for producing an implant, to a corresponding semifinished part or a corresponding implant, respectively.
