Description
Kupferlegierung Die Erfindung betrifft eine Kupferlegierung, die sich dadurch auszeichnet, daß sie besonders hart, abbrand- und verschleißfest ist und einen verhältnismäßig geringen spezifischen Widerstand besitzt. Erfindungsgemäß besteht die Legierung aus Kupfer mit einem Zusatz von Thorium. Praktisch kommen Thoriumgehalte von i bis 5oo/o in Frage. Die besten Ergebnisse haben Legierungen geliefert, welche von 5 bis 30 % Thorium enthalten.Copper alloy The invention relates to a copper alloy that characterized by the fact that it is particularly hard, burn-off and wear-resistant and has a relatively low specific resistance. According to the invention the alloy consists of copper with an addition of thorium. Come in handy Thorium contents of 1 to 500 per cent are possible. Alloys have the best results which contain from 5 to 30% thorium.
Die neue Legierung eignet sich besonders für die Herstellung von Schweißelektroden und Schweißkontakten. Für diese Verwendungszwecke ist sie durch ihre Härte, die Abbrand- und Verschleißfestigkeit und durch den geringen spezifischen Widerstand besonders gut geeignet. Es hat sich gezeigt, daß Schweißkontakte aus der Legierung nach der Erfindung nicht nur dauernd blank bleiben, sondern auch eine wesentlich größere Schalthäufigkeit zulassen als die bisher für diesen Zweck bekannten Werkstoffe. Die Brinellhärte beträgt bis zu 250, ohne daß zum Erreichen dieser Härte eine mechanische Nachbearbeitung durch Formänderung oder sonstige Vergütung notwendig wäre. Die mechanische Bearbeitbarkeit läßt sich durch einen Zusatz von Silber, vorzugsweise in einer Menge von i bis ioo/o, wesentlich verbessern. Durch Walzen und Hämmern können Formänderungen in weitem Umfange vorgenommen werden.The new alloy is particularly suitable for the production of welding electrodes and welding contacts. For these purposes it is due to its hardness that Resistance to erosion and wear and due to the low specific resistance particularly well suited. It has been shown that welding contacts made of the alloy according to the invention not only remain permanently blank, but also an essential one allow greater switching frequency than the materials previously known for this purpose. The Brinell hardness is up to 250 without a mechanical hardness to achieve this Post-processing by changing the shape or other remuneration would be necessary. The mechanical Machinability can be increased by adding silver, preferably in an amount from i to ioo / o, improve significantly. Shape changes can be caused by rolling and hammering to be made to a large extent.
