Beschreibung
Zusammenfassung:	The invention relates to a metallic sliding bearing composite material (2) comprising a supporting layer (4), in particular of steel, a copper-based layer (6) with tin or aluminium or nickel or zinc or combinations thereof, and comprising a sputtered running layer (8), in particular aluminium-based, facing a part involved in the sliding; in order to be able to produce the material more cost-effectively, it is proposed according to the invention that the copper-based layer (6) is a sputtered layer and has a thickness of at least 20 µm and that the copper-based layer (6) is sputtered directly onto the supporting layer (4) or onto an intermediate layer of a thickness of less than 20 µm that has been applied directly to the supporting layer (4). The invention also relates to a method for producing a sliding bearing composite material.
