Description

Palladium-Silber-Kupfer-Legierungen Die Erfindung betrifft eine Legierungstype, die Palladium, Silber und Kupfer enthält und sich durch einen Schmelzpunkt auszeichnet, der erheblich höher als der von Münzensilberlegierungen ist; und die ausreichend hohe Härte, elektrische und thermische Leitfähigkeit sowie Beständigkeit gegen Funkenanfressung besitzt, um sie besonders geeignet - für elektrische Kontakte bei Relais, Schaltern u. dgl. zu machen.Palladium-silver-copper alloys The invention relates to a type of alloy which contains palladium, silver and copper and is characterized by a melting point, which is significantly higher than that of coin silver alloys; and the sufficient high hardness, electrical and thermal conductivity and resistance to spark pitting possesses to make them particularly suitable - for electrical contacts in relays, switches and the like.

Die Billigkeit dieser Legierungen in Verbindung mit ihrer relativ hohen Beständigkeit gegen Zerfall urnd Freiheit von der Tendenz zum Klebenbleiben sind von erheblicher wirtschaftlicher Bedeutung.The cheapness of these alloys combined with their relative high resistance to decay and freedom from the tendency to stick are of considerable economic importance.

Die Erfindung schafft eine Legierung aus Palladium, Kupfer und Silber, die aus weniger als 2 5 % Palladium besteht; während der Rest durch Silber und Kupfer gebildet wird. Der Pallädiumgehalt ist genügend hoch, um den Schmelzpunkt der Legierung erheblich zu erhöhen und die Homogenität der Legierung zu steigern.The invention provides an alloy of palladium, copper and silver which consists of less than 25 % palladium; while the rest is made up of silver and copper. The palladium content is high enough to increase the melting point of the alloy considerably and to increase the homogeneity of the alloy.

Die neue Legierung enthält i bis 5o% Kupfer und ist frei von Eisen und dergleichen Metallen, die zur Beeinträchtigung der Duktilität der Legierung führen.The new alloy contains 1 to 50% copper and is free of iron and the like metals, which can adversely affect the ductility of the alloy to lead.

Zur Herstellung der Legierung können die Schmelzverfahren Verwendung finden, die für Edelmetalle üblich sind. Es hat sich gezeigt, daß zur Erzielung gesunder Gußstücke kurz vor dem Gießen eine kleine Menge eines Desoxydierungsmittels aus einer Gruppe von Stoffen zugesetzt werden kann, die Mangan, Zink, Silicium, Bor, Magnesium, Calcium oder Verbindungen öder Mischungen derselben enthält, während mit anderen Stoffen gleichgünstige Ergebnisse nicht erzielt werden.The melting processes can be used to produce the alloy that are common for precious metals. It has been shown that to achieve For healthy castings, apply a small amount of a deoxidizer just before casting can be added from a group of substances that include manganese, zinc, silicon, Boron, magnesium, calcium or compounds or mixtures thereof, while similar results cannot be achieved with other substances.

Die Legierungen können ferner zur Erhöhung ihrer Eigenschaften, besonders ihrer Festigkeit, einer Wärmebehandlung unterzogen werden, beispielsweise durch Erwärmung, nachherige Abschreckung und gegebenenfalls durch nachträgliches Altern bei geeigneten Temperaturen.The alloys can also be used to increase their properties, especially their strength, subjected to a heat treatment, for example by Warming, subsequent deterrence and, if necessary, subsequent aging at suitable temperatures.
