Zusammenfassung: | To provide a sliding bearing element which has a lead-free, sulfur-containing cast alloy layer on a copper basis, and in which the effects of sulfur on the alloy are reduced.SOLUTION: A multi-layer sliding bearing element (1) is provided that contains a supporting metal layer (3), a lead-free copper base alloy layer (4) and a sulfide-containing precipitate (10). The copper base alloy contains 0.1 wt.% to 3 wt.% of sulfur, 0.01 wt.% to 4 wt.% of iron, less than 2 wt.% of phosphorus, 0.1 wt.% to 49 wt.% of the total of at least one element of a first group consisting of zinc, tin, aluminum, manganese, nickel, silicon, chromium and indium, and 0 wt.% to 2 wt.% of the total of at least one element of a second group consisting of silver, magnesium, indium, cobalt, titanium, zirconium, arsenic, lithium, yttrium, calcium, vanadium, molybdenum, tungsten, antimony, selenium, tellurium, bismuth, niobium and palladium, and the balance copper.SELECTED DRAWING: Figure 1
