Description

Legierungen aus Platinmetallen, die sich insbesondere für Federspitzen eignen. In unserem Patent 350703 haben wir eine Osmiumlegierung beschrieben, welche sich besonders für Federspitzen eignet und deren Hauptbestandteile (mehr als 70 Prozent) aus Osmium und der Rest aus anderen Platinmetallen besteht. Eingehende Versuche haben nun gezeigt, daß das Osmium zum großen Teil ersetzt werden kann durch Ruthen, ohne daß die besonderen Eigenschaften, die für den Gebrauch maßgebend sind, geändert werden. Es hat sich gezeigt, daß Legierungen, welche 4.o bis 6o Prozent Ruthen, 35 bis 5o Prozent Osmium und 5 bis 15 Prozent Platin enthalten, für den vorliegenden Zweck gut brauchbar sind. Selbstverständlich können diese Legierungen auch für andere Zwecke als für Federspitzen, z. B. für Kompaßpinnen u. dgl., Verwendung finden.Alloys made of platinum metals, which are particularly suitable for pen nibs. In our patent 350703 we described an osmium alloy which is particularly suitable for nibs and whose main components (more than 70 percent) consist of osmium and the rest of other platinum metals. Extensive experiments have now shown that the osmium can be largely replaced by rods without changing the special properties that are decisive for its use. It has been shown that alloys which contain 40 to 60 percent ruthenium, 35 to 50 percent osmium and 5 to 15 percent platinum are very useful for the present purpose. Of course, these alloys can also be used for purposes other than nibs, e.g. B. for compass tiller and the like., Use.
