Description

Lagermetall Es sind Lagermetalle auf der Basis Kupfer-Zinn-Nickel bekannt, deren Zinngehalt io°/° und mehr und deren Nickelgehalt etwa 30/0 beträgt, während der Rest aus Kupfer besteht. Diese Lagermetalle zeichnen sich durch große Härte aus, und sie sind daher vornehmlich für Zwecke verwendet worden, wo es auf diese Eigenschaft ankam. Der hohe Zinnanteil verteuert den Preis der bekannten Lagermetalle außerordentlich.Bearing metal These are bearing metals based on copper-tin-nickel known whose tin content is 10 ° / ° and more and whose nickel content is about 30/0, while the rest is made of copper. These bearing metals are characterized by large Hardness, and they have therefore primarily been used for purposes where there is on this property arrived. The high proportion of tin increases the price of the known bearing metals extraordinary.

Gegenstand der Erfindung ist nun eine Lagermetalllegierung auf der Basis Kupfer-Nickel-Zinn, die neben großer Härte insbesondere eine hohe Zähigkeit, große Zugfestigkeit und eine besonders gute Dehnung aufweist. Die Legierung erstarrt mit dichterem Korn als die bekannten Lagermetallegierungen, so daß sie im besonderen Maße abnutzungsfest ist. Erreicht werden diese günstigen Eigenschaften bei der Lagermetalllegierung nach dieser Erfindung auf Grund der Erkenntnis, daß in einer Kupfer-Zinn-Nickel-Legierung die Summe der Anteile von Zinn und Nickel mindestens io°/°, höchstens aber 16% ausmachen muß, und daß innerhalb dieser Spannen der Gehalt an Zinn mindestens 5o0/0, höchstens aber 70°/° der Summe der Gehalte an Zinn und Nickel betragen darf. Unter Anwendung dieser Erkenntnis ergibt, sich beispielsweise eine Kupfer-Zinn-Nickel-Legierung mit 60/0 Zinn, 60/0 Nickel, Rest Kupfer. Diese Legierung läßt sich vorzüglich auf Lager vergießen, die bei großer Härte von hoher Zähigkeit, guter Zugfestigkeit, großer Dehnung und geringer Abnutzung sind.The invention now relates to a bearing metal alloy on the Based on copper-nickel-tin, which in addition to great hardness, in particular, high toughness, has great tensile strength and particularly good elongation. The alloy solidifies with denser grain than the known bearing metal alloys, so that they in particular Dimensions is wear-resistant. These favorable properties are achieved with the bearing metal alloy according to this invention on the basis of the knowledge that in a copper-tin-nickel alloy the sum of the proportions of tin and nickel is at least 10%, but not more than 16% must, and that within these ranges the tin content is at least 5o0 / 0, at most but 70% of the sum of the tin and nickel contents may be. Using This finding results, for example, in a copper-tin-nickel alloy with 60/0 tin, 60/0 nickel, the rest copper. This alloy works excellently Potting bearings, which with great hardness, high toughness, good tensile strength, high elongation and low wear.

Man kann die Eigenschaften der Lagerlegierung nach dieser Erfindung noch dadurch weiter verbessern, daB man ihnen Zuschläge an einem oder mehreren der Elemente Vanadium, Tantal, Molybdän, Titan, Wolfram, Cer, Beryllium oder Bor in Mengen von insgesamt 0,05 bis 2,000/0 zusetzt:--The properties of the bearing alloy according to this invention can be further improved by adding additions to one or more of the elements vanadium, tantalum, molybdenum, titanium, tungsten, cerium, beryllium or boron in total amounts of 0.05 to 2.000 / 0 adds: -
