Description

Magnetische Legierung, insbesondere zur induktiven Belastung von Telegraphen-und Telephonkabeln Magnetische Legierungen aus Nickel, Eisen und Kupfer mit überwiegendem Nickelgehalt und geringem Manganzusatz sind bekannt. Je nach der Zusammensetzung weisen sie entweder hohe, aber von der Feldstärke abhängige Anfangspermeabilität auf, oder aber niedrige und konstante Anfangspermeabilität. Beispielsweise hat eine bekannte Legierung folgender Zusammensetzung: Nickel 70,5 %, Eisen 18,5 0/0, Kupfer 10,5 %, Mangan o,5 0/0 eine Anfangspermeabilität von 5 300 für Feld-.stärken in der Nähe von Null, dagegen von 18 400 für die Feldstärke o,io. Für die nachstehende, ganz. ähnlich zusammengesetzte Legierung: Nickel 65,5 0/0, Eisen 17 0/0, Kupfer 17 0(0, Mangan 0,5 % hingegen sind die entsprechenden Werte der Anfangsperineabilität 3 20o und q. 500.Magnetic alloy, in particular for inductive loading of telegraph and telephone cables. Magnetic alloys made of nickel, iron and copper with a predominant nickel content and a small amount of manganese are known. Depending on the composition, they either have a high initial permeability, which is dependent on the field strength, or else a low and constant initial permeability. For example, a known alloy has the following composition: Nickel 70.5%, iron 18.5 0/0, copper 10.5%, manganese o, 5 0/0 an initial permeability of 5300 for field .stärken near zero , on the other hand from 18 400 for the field strength o, io. For the following, quite. Alloys with a similar composition: nickel 65.5 0/0, iron 17 0/0, copper 17 0 (0, manganese 0.5%, however, the corresponding values of the initial perineability are 3 20o and q. 500.

Erfindungsgemäß ist nun eine magnetische Legierung zur induktiven Belastung von Telegraphen- und Telephonkabeln folgendermaßen zusammengesetzt: Eisen 14 bis 15 0/0, Kupfer 15 0,f0, Nickel der Rest mit oder ohne einen kleinen Zusatz von Mangan, der 0,5 % nicht überschreitet.According to the invention is now a magnetic alloy for inductive The load on telegraph and telephone cables is composed as follows: Iron 14 to 15 0/0, copper 15 0, f0, nickel the rest with or without a small addition of manganese not exceeding 0.5%.

Wenn diese Legierung in geeigneter Weise ausgeglüht ist, so ist ihre magnetische Permeabilität nahezu unabhängig von der-Stärke des Feldes innerhalb der Grenzen: H _-_- o,ooi und H - o, i Gauß.When this alloy is suitably annealed, so is yours magnetic permeability almost independent of the strength of the field within the limits: H _-_- o, ooi and H - o, i Gauss.

Z. B. hat eine Legierung, bestehend aus Nickel 70 0/0, Eisen 15 0/0, Kupfer 15 % mit einer Spur von Mangan, nachdem sie zu feinem Draht ausgezogen und ausgeglüht war, bei der Prüfung folgendes ergeben: H - o,ooi : 6 300, H - o,oi : 6 8oo, H - o,o5 : 7 d.oo, H .- o, i : 8 Zoo.E.g. an alloy consisting of nickel 70 0/0, iron 15 0/0, Copper 15% with a trace of manganese after being drawn to fine wire and was annealed, the test results in the following: H - o, ooi: 6 300, H - o, oi: 6 8oo, H - o, o5: 7 d.oo, H .- o, i: 8 Zoo.

Der hohe und dabei gleichmäßige Wert ihrer Anfangspermeabilität ist eine Eigenschaft, die säe in Gestalt von Band oder Draht sehr brauchbar macht für die induktive Belastung von Telegraphen- und Telephonkabeln.The high and at the same time uniform value of their initial permeability is a property which, in the form of tape or wire, would make it very useful for the inductive loading of telegraph and telephone cables.

Die Legierung kann einen Zusatz von Mangan im Betrage von weniger als o,5 % erhalten; sie kann auch eine geeignete desoxydierende Substanz enthalten, soll jedoch keine Spur von Kohlenstoff aufweisen.The alloy may have an addition of manganese in the amount of less obtained as 0.5%; it can also contain a suitable deoxidizing substance, however, should not have any trace of carbon.

Die Legierung wird zu ihrer angegebenen Verwendung in Streifen-, Band- oder Drahtform gebracht und in bekannter Weise, entweder vor oder nach dem Aufbringen auf das Kabel, einer Wärmebehandlung unterworfen, bei der sie auf geeignete Temperatur erhitzt und derart gekühlt wird, daß ihre magnetischen Eigenschaften sich ausbilden.The alloy is used for its specified use in strip, ribbon or brought into wire form and in a known manner, either before or after application on the cable, subjected to a heat treatment in which it reaches the appropriate temperature heated and cooled in such a way that their magnetic properties develop.
