 EMI1.1 
 



   Es sind bereits verschiedene Legierungen bekannt, die nach geeigneter thermischer Behandlung hohe Permeabilität sowie geringe Verluste bei kleinen magnetisierenden Kräften zeigen. Derartige Legierungen können beispielsweise bei elektrischen Signalleitungen zum Aufbau der Kerne für die Belastungsspulen oder im Falle eines gleichförmig belasteten Leiters als Material für dessen Belastungshülle dienen. Unter den bereits bekannten Legierungen besitzen diejenigen, bei denen die Anfangspermeabilität durch geeignetes Glühen auf einen besonders hohen Wert gebracht werden kann, die unangenehme Eigenschaft, im Zustand der starken Magnetisierbarkeit durch mechanische Beanspruchungen an magnetischer Güte zu verlieren.

   Es   müssen   deshalb besondere, teilweise   umständliche   Wege eingeschlagen werden, um diese Legierungen, beispielsweise bei ihrer Verwendung als Belastungsmaterial für gleichförmig belastete Signalleiter, im Zustand der starken   Magnetisierbarkeit zu erhalten.   



   Gegenstand der vorliegenden Erfindung ist eine bisher nicht vorgeschlagene Legierung, die gleichfalls durch geeignete thermische Behandlung auf sehr günstige magnetische Werte gebracht werden kann, die aber von den bereits bekannten Legierungen den Vorzug besitzt, in dem Zustande starker Magnetisierbarkeit nicht in dem Masse wie die bisher bekannten Legierungen gegen   mechanische   Beanspruchungen empfindlich zu sein.

   Erfindungsgemäss ist die aus Eisen, Aluminium und Silizium bestehende Legierung so zusammengesetzt, dass der Aluminiumgehalt den Siliziumgehalt   überwiegt.   Es sind schon aus den gleichen drei Komponenten bestehende Legierungen bekannt, die sich aber von der   erfindungsgemässen   Legierung dadurch unterscheiden, dass sie weniger Aluminium als Silizium enthalten ; es sind ferner Eisen-und Aluminiumlegierungen bekannt, welche mehr Aluminium als Silizium, dann aber nur Spuren an Silizium in einer Menge von weniger als 015% enthalten. Vorzugsweise geeignet ist eine Legierung, gemäss der Erfindung, die neben Eisen etwa 1% Aluminium und etwa 07% Silizium enthält.

   Diese Legierung erhält günstige magnetische Eigenschaften, indem man sie in Draht-oder Bandform bringt und in dieser Form durch einen auf etwa   8500 C   geheizten Ofen mit einer Geschwindigkeit von 3-5 in je Minute zieht.

 EMI1.1
 



   Various alloys are already known which, after suitable thermal treatment, show high permeability and low losses with small magnetizing forces. Such alloys can be used, for example, in electrical signal lines to build the cores for the load coils or, in the case of a uniformly loaded conductor, as the material for its load sheath. Among the alloys already known, those in which the initial permeability can be brought to a particularly high value by suitable annealing have the unpleasant property of losing magnetic quality due to mechanical stresses in the state of strong magnetizability.

   Therefore, special, sometimes cumbersome ways must be taken in order to keep these alloys, for example when they are used as loading material for uniformly loaded signal conductors, in the state of strong magnetizability.



   The subject of the present invention is an alloy that has not been proposed so far, which can also be brought to very favorable magnetic values by suitable thermal treatment, but which has the advantage of the already known alloys, in the state of strong magnetizability not to the extent as the previously known Alloys to be sensitive to mechanical stress.

   According to the invention, the alloy consisting of iron, aluminum and silicon is composed in such a way that the aluminum content outweighs the silicon content. Alloys consisting of the same three components are already known, but differ from the alloy according to the invention in that they contain less aluminum than silicon; Furthermore, iron and aluminum alloys are known which contain more aluminum than silicon, but then only traces of silicon in an amount of less than 15%. An alloy according to the invention which, in addition to iron, contains about 1% aluminum and about 07% silicon is preferably suitable.

   This alloy is given favorable magnetic properties by making it into wire or strip form and drawing it in this form through a furnace heated to about 8500 C at a speed of 3-5 per minute.
