Description

Eisenlegierung für Gegenstände mit guter Kaltverformbarkeit Eisen-Aluminium-Legierungen und Eisenlegierungen, die neben anderen Legierungeleinenten auch Aluminium enthalten, sind für verschiedene Verwendungszwecke, beispielswe:se als magnetisch weiche sowie als hitzebeständ?ge Werkstoffe, bekannt. Ihr Aluminiumgehalt, der etwa bis zu 15 0/0 betragen kann, verschlechtert aber die Kaltverformbarkeit.Iron alloy for objects with good cold formability Iron-aluminum alloys and iron alloys, which contain aluminum in addition to other alloy elements, are for various uses, for example: se as magnetically soft as well known as heat-resistant materials. Their aluminum content, which is about up to 15 Can be 0/0, but worsens the cold formability.

Nach der Erfindung wird nun die Kaltverformbarleit aluminiumhaltiger Eisenlegierungen durch einen Schwefelgehalt von o, i bis o,5 0/0, vorzugsweise etwa 0,3 0/0, verbessert.According to the invention, the cold deformability of aluminum-containing iron alloys is now improved by a sulfur content of 0.1 to 0.5%, preferably about 0.3 %.

Diese Verbesserung ist insbesondere für die als magnetisch weiche sowie als hitzebeständige Werkstoffe, z. B. Widerstandswerkstoffe, verwendeten aluminiumhaltigen Eisenlegierungen von Bedeutung, weil diese vielfach in Form kalt gewalzter bzw. kalt gezogener Bänder bzw. Drähte verwendet werden.This improvement is particularly useful for those considered magnetically soft as well as heat-resistant materials, e.g. B. Resistance materials used containing aluminum Iron alloys are important because they are often in the form of cold-rolled or cold drawn tapes or wires can be used.
