Description

Metallegierung für ärztliche und zahnärztliche Zwecke. Nickel-Chrom-Legierungen mit hoher chemischer Widerstandsfähigkeit und mechanischer Bearbeitbarkeit, die einen Zusatz von etwas Silber haben, sind bekannt. Statt des Silbers kann man auch die doppelte Menge Kupfer anwenden, insbesondere wenn statt Nickel Kobalt verwendet wird. Diese Legierungen sind besonders für die chemische Industrie verwendbar. Die niedrigste Grenze für den Chromgehalt beträgt 25 Prozent.Metal alloy for medical and dental purposes. Nickel-chromium alloys with high chemical resistance and mechanical workability that have an addition of some silver are known. Instead of silver you can also use twice the amount of copper, especially if cobalt is used instead of nickel will. These alloys are particularly useful in the chemical industry. the the lowest limit for the chromium content is 25 percent.

Die Erfindung betrifft nun eine Legierung,. die als Ersatz für die in der Zahnheilkunde verwendeten Goldlegierungen und für Prothesen dienen soll. Solche Legierungen müssen den im Munde vorhandenen chemischen Einflüssen widerstehen, die. den Einflüssen der Säuren in der Chemie nicht gleichzusetzen sind.The invention now relates to an alloy. the replacement for the Gold alloys used in dentistry and for prostheses. Such alloys must withstand the chemical influences present in the mouth, the. are not to be equated with the influences of acids in chemistry.

Die Erfindung geht ebenfalls von einer Nickel-Chrom-Legierung aus, jedoch beträgt der Chromgehalt nur 17 Prozent, und es werden als Zusätze Aluminium, Silber und Kupfer verwendet. Eine solche Legierung besteht etwa aus 75 Teilen Nickel, 17 Teilen Chrom, z Teilen Aluminium, 5 Teilen Kupfer und einem Teil Silber.The invention is also based on a nickel-chromium alloy, but the chromium content is only 17 percent, and aluminum, silver and copper are used as additives. Such an alloy consists of about 75 parts nickel, 17 parts chromium, z parts aluminum, 5 parts copper and one part silver.

An und für sich ist auch der Zusatz von Aluminium zu Nickel-Chrom-Legierungen bekannt. Eine derartige Legierung ist aber bisher nur für elektrische Widerstandskörper vorgeschlagen, bei denen der Zusatz von Aluminium die Beständigkeit der Legierung bei hohen Temperaturen sichern soll, die im vorliegenden Fall nicht in Frage kommen.In and of itself there is also the addition of aluminum to nickel-chromium alloys known. Such an alloy has so far only been used for electrical resistance bodies proposed in which the addition of aluminum increases the durability of the alloy to secure at high temperatures, which are out of the question in the present case.
