Description
Die bisher zur Herstellung von Gebrauchsund Schmuckgegenständen, verwendeten Goldlegierungen haben eine solche Farbe, daß sie von derjenigen der Haut in hohem Maße ab-S stechen. Dies gilt in ungefähr gleicher Weise von allen bisher bekannten Rot-, Gelb- und Weißgoldlegierungen.The gold alloys previously used for the production of everyday objects and jewelry are of such a color as to be highly distinctive from that of the skin. This is roughly the same of all previously known red, yellow and white gold alloys.
Man hat zwar versucht, durch Färben der Gegenstände den Farbengegensatz zu mildern, der sehr oft stark ins Auge fällt und bei Gebrauchsgegenständen, die nicht unsehön auffallen sollen, wie z. B. bei Brillenfassungen, unerwünscht ist.Attempts have been made to soften the contrast of colors by coloring the objects, which is very often very eye-catching and with everyday objects that do not attract attention should, such as B. in eyeglass frames, is undesirable.
Diese Goldfärbungen sind jedoch, da nur oberflächlich, zu wenig dauerhaft.However, since these gold colors are only superficial, they are not permanent enough.
Man hat nun schon Goldlegierungen hergestellt, in welchen Metalle der Platingruppe enthalten sind. Auch ist es bekannt, die Metalle der Platingruppe in mehr oder minderGold alloys have now been produced, in which metals of the platinum group are included. It is also known that the metals of the platinum group in more or less
ao weitem Maße durch Metalle der Eisen-Nickel-: Gruppe, im besonderen durch Nickel zu ersetzen. Schließlich ist man bei der Herstellung solcher Legierungen anstatt von reinem Gold auch schon von Kupfergoldlegierungen ausgegangen. Die Zusammensetzung ist aber stets so gewählt worden, daß die Goldlegierungen bzw. Kupfergoldlegierungen von weißer Farbe waren.ao by far by iron-nickel metals: Group, in particular to be replaced by nickel. After all, you are in the process of manufacturing of such alloys, instead of pure gold, copper-gold alloys have already been used. The composition has always been chosen so that the gold alloys or copper gold alloys of were white in color.
Gold-Kupfer-Nickel-Legierungen mit 5 °/0 Nickel und 36,5 °/o Kupfer sowie 10 °/0 Nickel und 31,5 % Kupfer sind als blaßgelbe bzw. weiße Legierungen bekannt.Gold-copper-nickel alloys with 5 ° / 0 nickel and 36.5 ° / o copper, and 10 ° / 0 nickel and 31.5% copper are known as pale yellow or white alloys.
Gegenstand der vorliegenden Erfindung ist nun eine fleischfarbige Goldlegierung, die einem vorhandenen Bedürfnis, insbesondere auf optischem Gebiet, in weitgehendem Maße entspricht.The present invention is now a flesh-colored gold alloy that an existing need, especially in the optical field, to a large extent is equivalent to.
Die neue Legierung besteht aus 50 bis 60 °/0 Feingold, 34 bis 45 °/0 Kupfer und mehr als 5 und weniger als io°/0 Nickel.The new alloy consists of 50 to 60 ° / 0 fine gold, 34 to 45 ° / 0 copper and more than 5 and less than 10 ° / 0 nickel.
Es hat sich gezeigt, daß die mehr als 5 und weniger als 10 °/o Nickel ganz oder teilweise durch andere, dem Nickel ähnliche Metalle, nämlich Kobalt, Eisen oder Chrom, oder auch durch Metalle der Platingruppe, insbesondere durch Platin und Palladium, ersetzt werden können.It has been shown that the more than 5 and less than 10% nickel in whole or in part by other metals similar to nickel, namely cobalt, iron or chromium, or else be replaced by metals of the platinum group, in particular by platinum and palladium can.
Durch einen Zusatz von höchstens 4 °/o Zink wird die Legierung leichter bearbeitbar, ohne daß die Farbe eine wesentliche Änderung erfährt.The addition of not more than 4% zinc makes the alloy easier to work with, without the color undergoing any significant change.
Die neue Goldlegierung kann sowohl voll als auch doubliert mit einer Unterlage aus unedlem Metall verwendet werden.The new gold alloy can be made either fully or doubled with a backing base metal can be used.
