Title
(DE) GLEITELEMENT AUS EINER KUPFER-ZINK-LEGIERUNG
(EN) SLIDING ELEMENT CONSISTING OF A COPPER-ZINC ALLOY
(FR) ÉLÉMENT DE GLISSEMENT EN ALLIAGE CUIVRE-ZINC
Abstract
(DE)
Die Erfindung betrifft ein Gleitelement aus einer Kupfer-Zink-Legierung, welche die folgenden Bestandteile (in Gewichts-%) enthält: 60,0 bis 64,0 % Cu, 0,2 bis 0,5 % Si, 0,6 bis 1,2 % Fe, wahlweise noch bis maximal 1,5 % Sn, wahlweise noch bis maximal 0,25 % Pb, wahlweise noch bis maximal 0,08 % P, Rest Zn und unvermeidbare Verunreinigungen. Die Kupfer-Zink-Legierung weist ein aus α- und ß-Phase bestehendes Gefüge mit einem Volumenanteil der α-Phase von mindestens 90 % auf, wobei in das Gefüge Eisensilizide eingelagert sind.
(EN)
The invention relates to a sliding element consisting of a copper-zinc alloy containing the following components (in % by weight): 60.0 to 64.0 % Cu, 0.2 to 0.5 % Si, 0.6 to 1.2 % Fe, optionally also up to a maximum 1.5 % Sn, optionally also up to a maximum 0.25 % Pb, optionally also up to a maximum 0.08 % P, the remainder being Zn and unavoidable impurities. The copper-zinc alloy has a grain structure consisting of an α- and ß-phase with a volume content of the α-Phase of at least 90 %, and iron silicides are embedded in the grain structure.
