Description

Die Erfindung betrifft ein Lötmessing zum Verbinden von Messinggegenständen. Bisher wurden Hartlote mit bis zu 30 0/0 Silber, die zum Teil noch bis zu 5 o/o Phosphor enthalten, verwendet. Die Verknappung des Silbers gebot, für diese Lote ein Ersatzlot zu suchen. Es wurden daher auch schon silberfreie Hartlote, insbesondere das bekannte Phosphor-Kupfer, eine eutektische, sehr spröde Legierung aus etwa 8 o/o Phosphor, Rest Kupfer, und andere Hartlote auf Messinggrundlage mit bis zu ioo/0 Nickel verwendet.The invention relates to a soldering brass for joining brass objects. So far, hard solders with up to 30% silver, some of which still contain up to 5% phosphorus, have been used. The shortage of silver made it necessary to look for a replacement solder for these solders. There have therefore already silver-free braze alloys, in particular, the known phosphorus copper, a eutectic, very brittle alloy of about 8 o / o phosphorus, the remainder copper, and other hard solders on brass base with up to ioo / 0 is used nickel.

Diese Ersatzlote haben den Nachteil, daß sie einen hohen Schmelzpunkt besitzen, der etwa bei 725° C liegt, und daß sie in der Fließ- und Bindefähigkeit den silberhaltigen Loten nachstehen.These replacement solders have the disadvantage that they have a high melting point is about 725 ° C, and that it has the ability to flow and bind to the silver-containing Are inferior to plumbing.

Gemäß der Erfindung wird ein Lötmessing zum Verbinden von Messinggegenständen an Stelle von Silberhartloten verwendet, das dieselben Eigenschaften wie diese aufweist und aus etwa 1 o/0 Silicium, bis zu 5 o/o Phosphor, 58 bis 680/0 Kupfer und Rest Zink besteht.According to the invention, a Lötmessing is used for connecting brass articles in place of silver brazing alloys, the same characteristics as the latter has and up to 5 o / o phosphorus, 58 to 680/0 copper, the rest consisting of about 1 o / 0 silicon zinc.

Es ist zwar bekannt, daß Phosphor und Silicium, zinkhaltigen Loten zugesetzt, das Ausbrennen des Zinkes verhindern; doch war man der Ansicht, daß Phosphor und Zink das niedergeschmolzene Metall auf jeden Fall hart machen und seine Zähigkeit und Biegsamkeit vermindern.It is known that phosphorus and silicon are added to zinc-containing solders Prevent zinc burnout; but it was believed that phosphorus and zinc did that Molten metal definitely make it hard and its toughness and flexibility Reduce.

Weiter ist es auch bekannt, einem aus 6 Teilen Kupfer und 4 Teilen Zink bestehenden Lötmessing bis insgesamt 1 o/o an Silicium, Mangan, Eisen, Bor oder Zink hinzuzufügen. Diese Legierung stellt, verglichen mit dem erfindungsgemäßen Lot, einmal ein schwer herzustellendes Gemisch dar, und zum andern bewirken die geringen vorgeschlagenen Zusatzmengen praktisch keine Herabsetzung des Schmelzpunktes.It is also known to add up to a total of 1 o / o of silicon, manganese, iron, boron or zinc to a soldering brass consisting of 6 parts of copper and 4 parts of zinc. In comparison with the solder according to the invention, this alloy represents a mixture that is difficult to produce and, on the other hand, the small proposed additional amounts have practically no lowering of the melting point.

Versuche mit dem erfindungsgemäßen Lötrnessing haben gezeigt, daß es sich in seiner Fließ- und Bindefähigkeit von Silber-Kupfer-Hartloten mit bis zu 30 o/o Silber praktisch nicht unterscheidet. Auch die mechanischen Eigenschaften der damit hergestellten Hart-Experiments with the inventive Lötrnessing have shown that it differs in its flowability and binding capacity of silver-copper brazing alloys with up to 30 o / o silver practically no. The mechanical properties of the hard-

lötungen sind sehr gut. So beträgt die Festigkeit des Lotes 20 bis 22 kg/mm2 und entspricht damit derjenigen von oder Gußbronze. Der niedrigere punkt von etwa 6700 C ermöglicht ein wandfreies Löten.solderings are very good. The strength of the solder is 20 to 22 kg / mm 2 and thus corresponds to that of or cast bronze. The lower point of about 670 0 C allows a wall-free soldering.
