Description

Werkstoff für magnetische Zwecke Zur Herstellung der 1VIagnetkerne von Transformatoren und Dynamomaschinen, werden seit geraumer Zeit mit Vorteil siliciumlegierte Eisenbleche verwendet, die infolge ihres hohen spez. Widerstandes geringe Wirbelstromverluste und infolge ihrer geringen Koerzitivkraft geringe Hysteresisverluste besitzen. Diese Legierungen weisen aber den Nachteil auf, daß sie verhältnismäßig schwer veraxbeitbar sind. Es sind ferner für denselben Zweck Nickel-Eisen-Legierungen ausgebildet worden. Schließlich sind magnetische Legierungen mit hoher P:ermeabilität bekanntgeworden, die als wesentliche Bestandteile Nickel, Eisen und Kupfer enthalten. und denen zur Erhöhung des spez. Widerstandes ein Zusatz ran Silicium bis zu etwa t % gegeben worden ist. Über den Einfluß des Siliciums auf die Wattverluste der erwähntem. ternären Legierungen war nichts bekannt.Material for magnetic purposes For the production of the 1V magnetic cores of transformers and dynamo machines have been silicon-alloyed with advantage for some time Iron sheets used, which due to their high spec. Resistance low eddy current losses and have low hysteresis losses due to their low coercive force. These However, alloys have the disadvantage that they are relatively difficult to process are. Nickel-iron alloys have also been formed for the same purpose. Finally, magnetic alloys with high P: permeability have become known, which contain nickel, iron and copper as essential components. and those for Increase of the spec. Resistance an additive ran silicon up to about t% has been. About the influence of silicon on the watt losses mentioned. ternary Alloys was not known.

Gemäß der Erfindung wird für Zwecke, bei denen es ,auf möglichst geringe Wattverluste ankommt, ein. Werkstoff verwendet, .der aus Nickel, Eisen und Silicium besteht. Ein Zusatz von Titan, der gelegentlich für ähnliche Legierungen vorgeschlagen worden. ist, soll in der Legierung nach der Erfindung nicht enthalten sein. Der Gehalt an Silicium beträgt bis 6%, der Nickelgehalt liegt bei mindestens 4o%, aber unter 75%. Diese Legierungen zeichnen. sich dadurch vor den für magnetische Zwecke bekannten Legierungen aus, daß sie im, besonders vorteilhafter Weise geringe Wattverluste mit guter Verarbeitbarkeit vereinigen. Legierungen derselben Zusammens@etzung sind an sich bekamt. Sie sind bisher aber lediglich für Zwecke verwendet worden, bei denen es auf höhe Oxydationsbeständigkeit oder seinen geringen Ausdehnungskoeffi4enten ankommt. Über ihre magnetischen Eigenschaften war nichts bekannt.According to the invention, for purposes where it is as low as possible Watt loss arrives, a. Material used, made of nickel, iron and silicon consists. An addition of titanium that is occasionally suggested for similar alloys been. should not be included in the alloy according to the invention. Of the The silicon content is up to 6%, the nickel content is at least 40%, but below 75%. Draw these alloys. in front of them for magnetic purposes known alloys that they in a particularly advantageous manner low watt losses combine with good workability. Are alloys of the same composition got in itself. So far, however, they have only been used for purposes which it has high resistance to oxidation or its low expansion coefficient arrives. Nothing was known about their magnetic properties.
