Description

Durch Warmrecken in Form gebrachte Gegenstände aus Kupfer-Zinn-Silicium-Legierungen Für Bau- und Maschinenteile aus Kupferlegierungen ist in verschiedenen Fällen eine hohe Festigkeit und große Korrosionsbeständigkeit notwendig. Da Zinn-Kupfer-Legierungen--in dieser Beziehung bessere Eigenschaften als z. B. die am meisten gebräuchlichen Zink-Kupfer-Legierungen besitzen, wird man wo es geht, Zinn-Kupfer-Legierungen verwenden.Objects made of copper-tin-silicon alloys, shaped by hot stretching For construction and machine parts made of copper alloys, there is a high strength and high corrosion resistance are necessary. Since tin-copper alloys - in this relationship has better properties than z. B. the most common zinc-copper alloys tin-copper alloys will be used wherever possible.

Die Herstellung von Gußstücken ist für Zinn-Kupfer- wie für andere Kupfer-Legierungen gleich. Während sich jedoch Zink-Kupfer-Legierungen gut warm schmieden und pressen lassen, treten Schwierigkeiten bei der Wärmereckurig der Zinn=Kupfer-Legierungen auf. Eine gewisse Warmreckbarkeit besitzen die Legierungen mit geringem Zinngehalt, und bis etwa io °/o Zinn läßt sich noch von Kaltreckbarkeit sprechen. Darüber hinaus besitzen die Legierungen so gut wie keine Reckbarkeit. Es ist bereits vorgeschlagen worden, die Zinn-Kupfer-Legierungen durch besondere Wärmebehandlung warrnpreßlar zu machen. Dieses Verfahren hat jedoch den Nachteil daß die Wärmebehandlung umständlich ist, lange Zeit in Anspruch nimmt und durch die erforderlichen hohen Glühtemperaturen kostspielig ist.Making castings is the same for tin-copper as it is for others Copper alloys the same. However, while zinc-copper alloys warm up well Forged and pressed, difficulties arise with the thermal rectification of tin = copper alloys on. Alloys with a low tin content have a certain hot stretchability, and up to about 10 per cent of tin can still be said to be cold stretchability. Furthermore the alloys have virtually no stretchability. It's already suggested The tin-copper alloys have been warrnpreßlar through special heat treatment close. However, this method has the disadvantage that the heat treatment is cumbersome takes a long time and due to the high annealing temperatures required is costly.

Nach der Erfindung wird die Warmreckban:eit der Zinn-Kupfer-Legierungen durch einen Zusatz von Silicium so erhöht, daß eine besondere Wärmevorbehandlung überflüssig ist. Die Wirkung des Siliciumzusatzes äußert sich sowohl- bei den Legierungen geringen Zinngehaltes in einer Steigerung als auch bei den Legierungen mit über etwa io °J, Zinn in .der Erzielung der erwünschten Eigenschaft.According to the invention, the hot strip is used with the tin-copper alloys so increased by the addition of silicon that a special heat treatment is superfluous. The effect of the addition of silicon is expressed both in the case of the alloys low tin content in an increase as well as with the alloys with over about 10% tin in order to achieve the desired property.

Die Höhe des Siliciumgehaltes richtet sich nach-der Höhe des Zinngehaltes und schwankt zwischen o, i bis 3 °/o.The level of the silicon content depends on the level of the tin content and varies between 0.1 and 3 per cent.

Aus den erfindungsgemäßen Legierungen lassen sich z. B.. bei etwa 650° Preßteile auf mechanischen Pressen ohne besondere Schwierigkeiten herstellen.From the alloys according to the invention z. B .. at about Produce 650 ° pressed parts on mechanical presses without any particular difficulties.
