Das Löten des Magnesiums und seiner Legierungen bereitet noch große Schwierigkeiten. Das Verhalten der mit bisher bekannten Loten hergestellten Lötstellen in bezug auf Festigkeit und chemische Beständigkeit bestätigt diese Behauptung.The soldering of magnesium and its alloys is still very difficult. The behavior of the soldered joints made with previously known solders in terms of strength and chemical resistance confirms this claim.

Es ist bekannt, daß sich nur Cadmium in jedem beliebigen Verhältnis mit Magnesium und solchen Legierungen, in welchen das Magnesium überwiegt, ohne Eutektik legieren läßt, wobei eine starke Diffusion der beiden Metalle eintritt. Es lag daher nahe, aus Cadmium oder überwiegend aus Cadmium bestehende Lote zum Löten von Magnesium und t5 seinen Legierungen zu verwenden. Die Mängel dieser Lote bestehen darin, daß das Cadmium beim Lötvorgang in das Magnesium zu stark hineindiffundiert und beide Metalle an der Lötstelle eine Verbindung· eingehen, die sehr spröde und wenig korrosionsbeständig ist.It is known that only cadmium is in any proportion with magnesium and those alloys in which magnesium predominates without eutectics leaves, with a strong diffusion of the two metals occurs. It was therefore an obvious choice to use cadmium or to use solders consisting predominantly of cadmium for soldering magnesium and t5 its alloys. The deficiencies These solders consist in the fact that the cadmium diffuses too much into the magnesium and both metals during the soldering process at the soldering point a connection is made which is very brittle and not very corrosion-resistant is.

Gemäß der Erfindung werden diese Nachteile der Lote mit dem überwiegenden Cadmiumgehalt vermieden und die für die Veras Wendung erforderlichen Eigenschaften erzielt. Die Erfindung besteht darin, daß das Lot Eisen in Verbindung mit einem anderen Metall enthält, das ermöglicht, den Schmelzpunkt des Eisens so weit herabzusetzen, daß es imstande ist, mit dem Cadmium eine aus Mischkristallen bestehende Legierung zu bilden. Der Vorteil einer solchen Zusammensetzung beruht auf der erzielten Bindung des Cadmiums, welche' eine nachträgliche 'ungünstige Verbindung des Cadmiums mit dem zu lötenden Magnesium beim Lötvorgang nicht zuläßt.According to the invention, these disadvantages of the solders with the predominant cadmium content become avoided and achieved the properties required for the Veras turn. The invention is that the solder iron in conjunction with another metal contains, which enables the melting point of iron to be lowered so far that it is able to get off with the cadmium Form mixed crystals existing alloy. The advantage of such a composition is based on the achieved binding of the cadmium, which is 'a subsequent' unfavorable Combination of the cadmium with the magnesium to be soldered during the soldering process does not allow.

Ein solches Metall ist z. B. das Zink, mit welchem sich Eisen legieren läßt. Die so gewonnene Legierung liegt in ihrem. Schmelzpunkt dem des Cadmiums nahe genug, um beide zu einer Legierung bringen zu können.Such a metal is e.g. B. zinc, with which iron can be alloyed. The one won in this way Alloy is in theirs. Melting point close enough to that of cadmium to to be able to bring both to one alloy.

Der Vorteil der erfindungsgemäßen Zusammensetzung des Lotes liegt also im Gegensatz zu dem bisherigen Bestreben, eine mögliehst tiefgehende Diffusion zu erreichen, gerade in einer gewissen Begrenzung der Diffusion und damit geringster Korrosionsgefahr. Dabei hat das Lot infolge seines Eisengehalts eine hohe Eigenfestigkeit und Zähigkeit, so daß es kalt schmiedbar ist; es hat ferner eine ausgezeichnete eigene Korrosionsbeständigkeit und haftet mit einer höheren als seiner eigenen Zerreißfestigkeit ohne Flußmittel am Magnesium.The advantage of the composition of the solder according to the invention is in contrast to the previous effort to achieve as deep a diffusion as possible, precisely in a certain limitation of diffusion and thus the lowest risk of corrosion. The solder has a high inherent strength and toughness due to its iron content, see above that it is cold forgeable; it is also excellent in its own corrosion resistance and adheres to it with greater than its own tensile strength without flux Magnesium.
