Beschreibung
Zusammenfassung:	A multi-layer sliding bearing element made from a composite material includes a supporting metal layer and a further layer formed of a cast alloy of a leadfree copper base alloy, in which sulfide precipitates are contained. The copper base alloy contains between 0.1 wt. % and 3 wt. % sulfur, between 0.01 wt. % and 4 wt. % iron, up to 2 wt. % phosphorus, at least one element from a first group consisting of zinc, tin, aluminum, manganese, nickel, silicon, chromium, indium of in total between 0.1 wt. % and 49 wt. %, and at least one element from a second group consisting of silver, magnesium, indium, cobalt, titanium, zirconium, arsenic, lithium, yttrium, calcium, vanadium, molybdenum, tungsten, antimony, selenium, tellurium, bismuth, niobium, palladium, wherein the summary proportion of the elements of the second group amounts to between 0 wt. % and 2 wt. %, and the balance is constituted by copper.
