Description
Messinglegierung Es ist bekannt, daß bestimmte Messinglegierungen durch gleichzeitigen Zusatz von Silizium und Zinn für Gußzwecke besonders geeignet werden, und daß ihre Festigkeitseigenschaften durch diese Zusätze eine wesentliche Verbesserung erfahren. Bisher konnte diese günstige Wirkung indessen nur an Legierungen beobachtet werden, die einen Kupfergehalt von 56 bis 58 % besitzen. Derartige Legierungen mit im Mittel o,8 °/o Silizium und z °/o Zinn können Festigkeitsw orte erreichen, die bei So kg/qmm liegen.Brass alloy It is known that certain brass alloys Particularly suitable for casting purposes due to the simultaneous addition of silicon and tin and that their strength properties are essential due to these additives Experience improvement. So far, however, this beneficial effect could only be achieved with alloys can be observed, which have a copper content of 56 to 58%. Such alloys with an average of 0.8% silicon and 2% tin, strength words can be achieved, which are so kg / qmm.
Es hat sich nun gezeigt, daß auch Messinglegierungen mit geringerem Kupfergehalt (So bis 56 °/a Cu) durch gleichzeitigen Zusatz von Silizium und Zinn verbessert werden können, so daß ihre Verwendung für Gußzwecke besonders vorteilhaft wird. Diese Verbesserung der genannten Legierungen gelingt, wenn die Zusätze von Silizium und insbesondrere von Zinn niedriger gehalten werden, als das bisher bei Legierungen mit höherem Kupfergehalt möglich war, und zwar müssen mit abnehmendem Kupfergehalt auch die Mengen der Silizium- und Zinnzusätze vermindert werden. Der Siliziumzusatz darf nur o,z bis o,8 und der Zinnzusatz nux o,r bis 0,41[" betragen. Werden diese Mengenverhältnisse genau eingehalten, so erreichen die Legierungen gemäß der Erfindung höhere Festigkeitseigenschaften als die bekannten Legierungen mit höherem Kupfergehalt. Ein Messing mit 54 % Cu, 0,5 % Si und o,2 bis 0,3 °/o Sn hat z. B. eine Festigkeit von 6o und mehr kg/qmm.It has now been shown that brass alloys with a lower Copper content (So up to 56 ° / a Cu) due to the simultaneous addition of silicon and tin can be improved, so that their use for casting purposes is particularly advantageous will. This improvement of the alloys mentioned succeeds if the additions of Silicon and in particular tin are kept lower than previously at Alloys with higher copper content was possible, and that with decreasing Copper content also the amounts of silicon and tin additives can be reduced. Of the The addition of silicon may only be o, z to 0.8 and the tin addition nux o, r to 0.41 [". If these proportions are precisely adhered to, the alloys achieve according to the invention higher strength properties than the known alloys with a higher copper content. A brass with 54% Cu, 0.5% Si and 0.2 to 0.3% Sn has z. B. a strength of 6o and more kg / sqmm.
