  Aluminium-Kupfer-Zinn-Legierung. 



   Den Gegenstand der Erfindung bildet eine Aluminium-Kupfer-Zinn-Legierung, die gegenüber den bekannten Legierungen dieser Art wertvolle Eigenschaften aufweist. 



   Die bisher bekannten Aluminium-Kupfer-Zinn-Legierungen liefern Gussstücke, die nicht   genügend homogen   sind und daher vor ihrer Bearbeitung auf der Drehbank oder dgl. durch Pressen verdichtet werden müssen. Ferner ist bei der   Bearbeitung solcher Gussstücke   auf der Drehbank oder dgl. reichliche Zuführung eines Schmiermittels erforderlich. Hiedurch wird die Herstellung von Gebrauchsgegenständen, die aus einer der bisher bekannten Aluminium-Kupfer-Zinn-Legierungen bestehen, wesentlich erschwert und verteuert. In besonders hohem Masse ist dies bei der Herstellung von Geschosszünderteilen der Fall. 



  Benutzt man nämlich bei der Bearbeitung dieser Teile auf der Drehbank oder dgl. die gebräuchlichen   Schmiermittel,   z. B. Öl, so wird die Herstellung noch dadurch weiter erschwert und verteuert, dass alsdann eine gründliche Reinigung der fertigen   StUck !'   erforderlich ist, da solche Schmiermittel eine Zersetzung der z. B. in den Satzstücken der   Brennzünder   zur Verwendung kommenden Pulvermasse   herbeiführen   würden. Die zur Reinigung der Teile zu benutzenden Laugen greifen   ausserdem   das Metall an. 



   Dagegen lassen sich   Gebrauchsgegenstände,   die der Erfindung gemäss aus einer Legierung von etwa 87% Aluminium, 8% Kupfer und 5% Zinn bestehen, wesentlich

  Aluminum-copper-tin alloy.



   The subject of the invention is an aluminum-copper-tin alloy which has valuable properties compared to the known alloys of this type.



   The previously known aluminum-copper-tin alloys provide castings which are not sufficiently homogeneous and therefore have to be compacted by pressing before being machined on the lathe or the like. Furthermore, when machining such castings on the lathe or the like, a large supply of lubricant is required. As a result, the production of articles of daily use which consist of one of the previously known aluminum-copper-tin alloys is made considerably more difficult and expensive. This is particularly the case in the manufacture of projectile fuse parts.



  If you use namely when machining these parts on the lathe or the like. The common lubricants, z. B. oil, the production is made even more difficult and expensive that then a thorough cleaning of the finished piece! ' is required because such lubricants cause decomposition of the z. B. would bring about powder mass coming to use in the sentences of the burner igniter. The alkalis to be used to clean the parts also attack the metal.



   On the other hand, articles of daily use which, according to the invention, consist of an alloy of approximately 87% aluminum, 8% copper and 5% tin, can be used substantially

 Tin fluctuate between 4-5 and 5 # 5%. In any case, however, the copper content must exceed the tin content.
