Description

Anschlußkontakt für elektrische Widerstandskörper für hohe Temperaturen. Vorliegende Erfindung betrifft einen Anschlußkontakt für elektrische WiderstandskÖrper für hohe Temperaturen. Er besteht aus einer Aluminiumbronze, die 87 bis 94 Prozent Kupfer, i bis 8 Prozent Silizium und i bis i:2 Prozent Aluminium enthält. Diese Bronze -zeichnet sich durch ihre Widerstandsfähigkeit ,legen den Sauerstoff der Luft in der Hitze aus. Durch den gleichzeitigen Zusatz von Silizium und Aluminium: in den angegebenen Mengen wird erreicht, @daß selbst bei stundenlangem Glühen an der Luft die Kontakte nicht oxydieren.Connection contact for electrical resistance bodies for high temperatures. The present invention relates to a connection contact for electrical resistance bodies for high temperatures. It consists of an aluminum bronze that is 87 to 94 percent Contains copper, i to 8 percent silicon and i to i: 2 percent aluminum. These Bronze - is characterized by its resilience, attach the oxygen to the Air in the heat. By adding silicon and aluminum at the same time: in the specified amounts it is achieved that even after glowing for hours the air does not oxidize the contacts.

Die Widerstandsfähigkeit gegen Oxydation würde auch-noch vorhanden sein, wenn man den Gesamtzusatz von Aluminium und Silizium über 13 Prozent hinaus steigert. Die Legierung ist :dann aber praktisch nicht mehr bearbeitbar. Nimmt man den Gesamtzusatz kleiner als io Prozent, .dann ist die Legierung vorzüglich bearbeitbar, sogar duktil.The resistance to oxidation would also still be present if you put the total addition of aluminum and silicon beyond 13 percent increases. The alloy is: but then practically no longer machinable. Taking the total addition less than 10 percent, then the alloy is excellently machinable, even ductile.
