Description

Silberlegierungen Reinsilber gilt vielfach als besonders widerstandsfähiger Baustoff für Behälter.Silver alloys Pure silver is often considered to be particularly resistant Building material for containers.

Es wurde nun gefunden, daß die Legierungen des Silbers mit Aluminium mit mindestens 8o°%o Silber, welche außerdem noch Arsen, Wismut oder Silicium in Mengen bis zu 7 Gewichtsprozenten oder Antimon in Mengen bis zu ro Gewichtsprozenten oder mehrere der genannten Stoffe enthalten, das Reinsilber hinsichtlich seiner Korrosionsbeständigkeit übertreffen. Dazu kommt noch, daß die Legierungen härter sind als das Beinsilber, dabei aber gut bearbeitbar bleiben. hie Legierungen stellen sich auch billiger als Beinsilber.It has now been found that the alloys of silver with aluminum with at least 80% o silver, which also contains arsenic, bismuth or silicon in Quantities up to 7 percent by weight or antimony in quantities up to ro percent by weight or contain several of the substances mentioned, the pure silver with regard to its Outperform corrosion resistance. In addition, the alloys are harder are as the leg silver, but remain easy to work with. here are alloys also cheaper than leg silver.

Die genannten Legierungen eignen sich vorzüglich zur Herstellung von chemischen Apparaten, Gefäßen, Rohrleitungen usw., bei denen es auf `?Widerstandsfähigkeit gegen Chemikalien, wie Säuren, insbesondere Salzsäure, Schwefelwasserstoff u. dgl., ankommt. Als Beispiel sei eine Gußlegierung folgender Zusammensetzung genannt: 8r,8°/" Silber, 9,31/1o Aluminium, 8,9"/" Antimon. Die Legierung ist zur Herstellung der verschiedensten Gebrauchsgegenstände geeignet, insbesondere auch für solche, die man bislang aus Reinsilber hergestellt hat.The alloys mentioned are particularly suitable for the production of chemical apparatus, vessels, pipelines, etc., for which there is a need for resistance against chemicals such as acids, especially hydrochloric acid, hydrogen sulfide and the like, arrives. A cast alloy with the following composition is mentioned as an example: 8r, 8 ° / " Silver, 9.31 / 10 aluminum, 8.9 "/" antimony. The alloy is used to manufacture the A wide variety of everyday objects suitable, especially for those who has so far been made from pure silver.
