" Zweiphasiges, nicht warmbrüchiges Messing mit Zirkoniumgehalt11 "Two-phase, non-hot-brittle brass with zirconium content 11
Die Erfindung betrifft Kupfer- und Zinklegierungen, die keine oder nur eine sehr geringfügige Warmbrüchigkeit aufweisen.The invention relates to copper and zinc alloys that have no or show only a very slight hot brittleness.
Diese Legierungen sind besonders zum Gießen geeignet. Es ist bekannt, daß handelsübliches Messing oft zur Herstellung von Armaturen mittels Kokillenguß verwendet werden. Man hat dabei festgestellt, daß ein Gußstück, das ein etwas komplizierteres Profil aufweist, leicht Risse und Bruchstellen aufweist.These alloys are particularly suitable for casting. It is known, that commercial brass are often used for the production of fittings by means of permanent mold casting. It was found that a casting which has a somewhat more complicated profile is easily cracked and broken.
Man hat festgestellt, daß dies auf den Umstand zurückzuführen ist, daß beim Abkühlen des Gußstücks in ihm Spannungen auftreten, die dazu führen können, daß noch vor der Verfestigung sich Risse bilden.It has been found that this is due to the fact that when the casting cools, stresses occur in it, which can lead to cracks forming before solidification.
Dieser Nachteil wird dann noch durch die heutige Tendenz verstärkt, daß das Gießen für Großserien in automatischen Kokillen erfolgt. Wir haben festgestellt, daß diese Warmbrüchigkeit im wesentlichen bei einer zweiphasigen Messinglegierung vermieden werden kann, wenn dieser Legierung ein geringer Prozentsatz von Zirkonium beigegeben wird; es wurde weiter festgestellt, daß dieser Prozentsatz zwischen 0, 005 und 0, 3 Gewichtsprozent schwanken kann.This disadvantage is then exacerbated by today's trend that the casting for large series takes place in automatic molds. We have found that this hot brittleness is essentially can be avoided with a two-phase brass alloy, when a small percentage of zirconium is added to this alloy will; it was further found that this percentage can vary between 0.005 and 0.3 percent by weight.

ORIGINAL INSPECTEDORIGINAL INSPECTED
Die erfindung s gemäß en Legierungen können durch Verwendung von Schrott erschmolzen werden und haben daher den Vorteil, daß sie praktisch die gleichen Kosten wie die gewöhnlichen Legierungen mit sich bringen, ohne jedoch warmbrüchig zu sein, und entgegen den Erwartungen wurde herausgefunden, daß die Wirksamkeit des Zirkoniums von der Anwesenheit von Fe und/oder Ni nicht ungünstig beeinflußt wird, wie dies stattdessen bei Bor der Fall ist, das außerdem den Nachteil hat, daß es auf der Oberfläche des GußsLilcks harte Stellen bildet.The alloys according to the invention can be melted by using scrap and therefore have the advantage that they bring practically the same costs as the usual alloys, but without being hot-brittle, and contrary In accordance with expectations, it has been found that the effectiveness of the zirconium is not unfavorable from the presence of Fe and / or Ni is affected, as is instead the case with boron, which also has the disadvantage that it leaks on the surface of the casting forms hard spots.
Die erfindung s gemäß en Legierungen enthalten zwischen 56, 5 und 65 % Cu, zwischen 42 und 30 % Zn, zwischen 0, 005 und 0, 3 % Zirkonium, dazu noch die üblichen Verunreinigungen Fe, Sn, Pb, Si, Ni, die im allgemeinen insgesamt weniger als 10 % und einzeln nicht mehr als 3 % ausmachen.The alloys according to the invention contain between 56, 5 and 65% Cu, between 42 and 30% Zn, between 0.005 and 0.3% Zirconium, plus the usual impurities Fe, Sn, Pb, Si, Ni, which are generally less than 10% and individually not more than 3%.
Die beigefügte Zeichnung zeigt zwei Querschnitte durch den Hauptteil eines Kokillenguß Stücks, das einerseits· mit der erfindungsgemäßen Legierung und andererseits beispielsweise mit normalem Messing hergestellt wurde. Mit gewöhnlichem Messing hat sich ein Ausschuß von bis zu 40 % ergeben, während mit der vorerwähnten Legierung keinerlei Ausschuß anfiel.The attached drawing shows two cross sections through the main part a chill casting piece that on the one hand · with the invention Alloy and on the other hand, for example, with normal brass. With ordinary brass one has Rejects of up to 40% result, while with the aforementioned alloy there was no rejects whatsoever.
Die erfindungsgemäße Legierung hatte in dem als Beispiel genannten Fall die folgende Zusammensetzung in Gewichtsprozenten: Cu 59, 5; Sn 0,8; Ni 0, 3; Mn 0, 3; Si 0, 03; Al 0,8; Fe 0,7; Pb 1,8; Zr 0,015; Rest Zn.The alloy according to the invention had in that mentioned as an example Case the following composition in percent by weight: Cu 59.5; Sn 0.8; Ni 0.3; Mn 0.3; Si 0.03; Al 0.8; Fe 0.7; Pb 1.8; Zr 0.015; Remainder Zn.
