Abstract
The invention relates to a piece of jewelry having a copper-containing gold alloy which consists of - 58.5 to 58.7 wt.% gold, - 26.9 to 32.6 wt.% copper, - 5.7 to 10.7 wt.% silver, - 1.0 to 3.0 wt.% palladium, and a remainder containing 0.7 to 2.2 wt.% zinc.
Description
Schmuckkörper jewelry body
Beschreibung description
Die Erfindung betrifft einen Schmuckkörper, wie ein Schmuckstück, insbesondere ein ringförmiges Schmuckstück, einen Teil eines Schmuckstückes oder ein Halbzeug für die Herstellung eines Schmuckstückes nach dem Oberbegriff des Anspruchs 1 , eine Schmuck-Legierung zur Herstellung eines solchen Schmuckkörpers und ein Verfahren zur Herstellung der Schmuck-Legierung. Der Schmuckkörper ist dabei aus einer Goldlegierung mit einem Anteil aus Kupfer hergestellt. The invention relates to a piece of jewelry, such as a piece of jewelry, in particular a ring-shaped piece of jewelry, a part of a piece of jewelry or a semi-finished product for the production of a piece of jewelry according to the preamble of claim 1, a jewelry alloy for the production of such a piece of jewelry and a method for producing the jewelry -Alloy. The jewelery body is made from a gold alloy with a proportion of copper.
Aus DE60310555T2 ist eine Legierung zur Herstellung von Uhren-, Schmuck- und Juwelierartikeln bekannt, die einen Goldanteil von wenigstens 75 Gew.-% und einen Kupferanteil von wenigstens 14 Gew.-% aufweist. Ferner ist beschrieben, wie bei derartigen Goldlegierungen in Abhängigkeit der Anteile von Kupfer und Silber ein Farbton von rot über rosa nach gelb erzielt werden kann. DE60310555T2 discloses an alloy for the production of watches, jewelery and jewellery, which has a gold content of at least 75% by weight and a copper content of at least 14% by weight. It is also described how a hue from red to pink to yellow can be achieved in gold alloys of this type, depending on the proportions of copper and silver.
Nachteilig an den bekannten Legierungen ist dabei, dass diese aufgrund des hohen Goldanteils relativ teuer in der Herstellung sind. Zudem besteht am Schmuckmarkt ein Bedarf an Legierungen, die über die bekannten Farbgoldlegierungen hinaus, insbesondere auch bei der Herstellung von Goldschmuck, neue Farbvarianten ermöglichen und dabei relativ kostengünstig herzustellen sind. A disadvantage of the known alloys is that they are relatively expensive to produce due to the high proportion of gold. In addition, there is a need on the jewelery market for alloys which, in addition to the known colored gold alloys, enable new color variants, in particular also in the manufacture of gold jewellery, and which can be produced relatively inexpensively.
Die Aufgabe der Erfindung ist es daher, bei einem gattungsgemäßen Schmuckkörper die genannten Nachteile zu vermeiden und eine neue Farbgebung zur Verfügung zu stellen. The object of the invention is therefore to avoid the disadvantages mentioned in a generic jewelry body and to provide a new color scheme.
Diese Aufgabe wird durch den Schmuckkörper aus einer kupferhaltigen Goldlegierung mit den Merkmalen des Anspruchs 1 gelöst. Dabei besteht die Goldlegierung aus wenigstens 58,5 bis maximal 58,7 Gew.-% Gold, wenigstens 26,9 bis maximal 32,6 Gew.-% Kupfer, wenigstens 5,7 bis maximal 10,7 Gew.-% Silber, wenigstens 1 ,0 bis maximal 3,0 Gew.-% Palladium und einem Rest, der wenigstens 0,7 bis
maximal 2,2 Gew.-% Zink aufweist, wodurch ein Schmuckkörper mit einem neuartigen Farbton gewonnen wird, der als champagnerfarben bezeichnet werden kann. This object is achieved by the jewelery body made from a copper-containing gold alloy with the features of claim 1. The gold alloy consists of at least 58.5 to a maximum of 58.7% by weight gold, at least 26.9 to a maximum of 32.6% by weight copper, at least 5.7 to a maximum of 10.7% by weight silver, at least 1.0 to a maximum of 3.0% by weight of palladium and a remainder of at least 0.7 to has a maximum of 2.2% by weight of zinc, resulting in a jewel body with a novel hue that can be described as champagne-colored.
In einer besonders vorteilhaften Ausführungsform besteht die Legierung aus 58,6 Gew.-%Gold, 29,0 bis 29,5 Gew.-% Kupfer, 8,5 bis 9,0 Gew.-% Silber, 1 ,9 bis 2,1 Gew.-% Palladium, und einem Rest, der zwischen 1 ,4 und 1 ,5 Gew.-% Zink aufweist. Mit einer derartigen Zusammensetzung kann eine besonders intensive Champagnerfarbe erzielt und eine besonders gute Verarbeitbarkeit der Gold-Kup- fer-Legierung gewährleistet werden. Zudem kann die Goldlegierung mit dem Champagnerfarbton auf diese Weise relativ kostengünstig hergestellt werden. In a particularly advantageous embodiment, the alloy consists of 58.6% by weight gold, 29.0 to 29.5% by weight copper, 8.5 to 9.0% by weight silver, 1.9 to 2. 1% by weight of palladium, and a remainder containing between 1.4 and 1.5% by weight of zinc. With such a composition, a particularly intense champagne color can be achieved and particularly good workability of the gold-copper alloy can be ensured. In addition, the gold alloy with the champagne hue can be produced relatively inexpensively in this way.
Ferner wird die oben genannte Aufgabe durch ein Verfahren gelöst, bei dem der Zinkanteil der Legierung wenigstens teilweise durch das Zusammenschmelzen von Messing mit den übrigen Bestandteilen gewonnen wird. Auf diese Weise kann der Zinkanteil der Schmelze besonders einfach hergestellt werden. Furthermore, the above object is achieved by a method in which the zinc content of the alloy is at least partially obtained by melting brass together with the other components. In this way, the zinc content of the melt can be produced particularly easily.
Vorteilhafterweise ist das hierbei eingeschmolzene Messing durch Cu63Zn37-Mes- sing gebildet, wodurch der gewünschte Zinkanteil besonders einfach und in exakter Menge eingeschmolzen werden kann. The brass melted in here is advantageously formed by Cu63Zn37 brass, as a result of which the desired proportion of zinc can be melted in particularly easily and in an exact quantity.
Nach Herstellung der entsprechenden Schmelze ist es vorteilhaft, wenn diese von Hand abgegossen wird, um auch kleine beziehungsweise besonders filigrane Schmuckkörper in dem Champagnerton herstellen zu können. After the corresponding melt has been produced, it is advantageous if this is cast by hand in order to be able to produce small or particularly filigree pieces of jewelry in the champagne tone.
Alternativ oder zusätzlich hierzu kann die Schmelze, insbesondere bei größeren Mengen einem Stranggussverfahren zugeführt werden, um beispielsweise Halbzeuge herstellen zu können, die für die spätere Weiterverarbeitung zu Schmuckstücken dienen können, wie beispielsweise für die Herstellung ganz oder teilweise champagnerfarbener Schmuckringe.
Im Folgenden wird eine bevorzugte Zusammensetzung der Schmelze zur Herstellung der Schmucklegierung und des Schmuckkörpers mit einem besonders strahlenden Champagnerfarbton angegeben: Alternatively or additionally, the melt can be fed to a continuous casting process, especially in larger quantities, in order to be able to produce, for example, semi-finished products that can later be processed into pieces of jewelry, such as for the production of completely or partially champagne-colored jewelry rings. A preferred composition of the melt for the production of the jewelery alloy and the jewelery body with a particularly radiant champagne color is given below:
Beispiel: Example:
58,6 Gew.-% Gold, 58.6% by weight gold,
26,7 Gew.-% Kupfer, 26.7% by weight copper,
8,7 Gew.-% Silber, 8.7% by weight silver,
2,0 Gew.-% Palladium 2.0% by weight palladium
4,0 Gew.-% CuZn37-Messing
4.0% by weight CuZn37 brass
