LEGA PER LA PRODUZIONE DI MONILI. ALLOY FOR JEWELERY PRODUCTION.
DESCRIZIONE DESCRIPTION
Campo tecnico Technical field
L’invenzione riguarda una lega per la produzione di monili, in particolare per gioielli o articoli di bigiotteria. L’invenzione si riferisce anche a oggetti, in particolare monili, prodotti con questa lega. The invention relates to an alloy for the production of jewelery, in particular for jewelery or costume jewelery items. The invention also refers to objects, in particular jewelry, produced with this alloy.
Stato della tecnica State of the art
II mercato della gioielleria e bigiotteria conosce un gran numero di leghe d’oro o di altri metalli preziosi, come per esempio il platino per realizzare monili. L’oro e il platino sono metalli non facilmente ossidabili, ma hanno un costo molto elevato. Il peso dell'ero e del platino à ̈ relativamente alto,<'>ciò che limita le dimensioni ragionevolmente realizzabili nei gioielli, in particolare nel caso degli orecchini. The jewelery and costume jewelery market knows a large number of gold alloys or other precious metals, such as platinum for making jewelery. Gold and platinum are metals that are not easily oxidizable, but they have a very high cost. The weight of the hero and platinum is relatively high, <'> what limits the size reasonably achievable in jewelry, particularly in the case of earrings.
Per offrire monili anche a prezzi contenuti, il mercato della bigiotteria ha sviluppato diverse leghe a base di rame e zinco, componenti dell’ottone, che hanno un costo inferiore rispetto alle leghe d’oro ma che presentano diversi svantaggi. In order to offer jewels even at low prices, the costume jewelery market has developed various alloys based on copper and zinc, components of brass, which have a lower cost than gold alloys but which have several disadvantages.
Per evitare l’ossidazione della lega e quindi l’alterazione dell’aspetto dorato si rende necessaria una copertura dell’oggetto, per esempio con uno strato d’oro attraverso una placcatura con metodi galvanici. Questo strato però à ̈ soggetto a usura. Le leghe che sostituiscono le classiche leghe d’oro, dovuto a processi d’ossidazione, nella maggior parte dei casi non mantengono l’aspetto dorato durante il tempo e necessitano frequenti puliture o placcature con leghe ad elevato contenuto d’oro. In più, queste leghe spesso non imitano perfettamente il metallo prezioso e le sue leghe nell’aspetto esterno, cioà ̈ nella colorazione e nel grado di lucentezza. To avoid oxidation of the alloy and therefore the alteration of the golden aspect, it is necessary to cover the object, for example with a layer of gold through a plating with galvanic methods. However, this layer is subject to wear. The alloys that replace the classic gold alloys, due to oxidation processes, in most cases do not maintain their golden appearance over time and require frequent cleaning or plating with high gold content alloys . In addition, these alloys often do not perfectly imitate the precious metal and its alloys in the external appearance, that is in the coloring and in the degree of luster.
Presentazione dell’invenzione Presentation of the invention
Lo scopo della presente invenzione à ̈ proporre una lega perfezionata che superi gli svantaggi sopra elencati. Principalmente, lo scopo della presente invenzione à ̈ proporre una lega a bassa caratura di metalli preziosi, che, oltre a non essere facilmente ossidabile e ad avere una buona lavorabilità , imiti l'aspetto e la lucentezza dei metalli preziosi e delle loro leghe. The object of the present invention is to propose an improved alloy which overcomes the disadvantages listed above. Mainly, the purpose of the present invention is to propose a low-carat alloy of precious metals, which, in addition to not being easily oxidizable and having good machinability, imitates the appearance and luster of precious metals and their alloys.
Gli scopi prima ricordati e altri che verranno meglio evidenziati in seguito sono raggiunti da una lega per la produzione di monili, che à ̈ costituita da: 7-16 % in peso di argento; 15 - 36 % in peso di zinco; The purposes mentioned above and others that will be better highlighted later are achieved by an alloy for the production of jewelry, which is made up of: 7-16% by weight of silver; 15 - 36% by weight of zinc;
0,1 - 4,17 % in peso di un metallo o una combinazione di metalli scelti fra a) oro e platino, b) oro e palladio c) oro, platino e palladio, d) platino, e) palladio, e f) platino e palladio; 0 - 0,5 % in peso di uno o più metalli scelti fra iridio, germanio, silicio, osmio, stagno, indio e gallio, preferibilmente iridio, germanio, silicio e gallio; e il resto rame. E’ da intendersi che le leghe ivi descritte possono sempre contenere altri elementi, cioà ̈ elementi che non vengono elencati come componenti compositori della lega, in forma di tracce in quantità complessive fino allo 0,2 % in peso. Queste tracce derivano da impurità delle materie prime o sono residui di materiali ausiliari usati durante la produzione o lavorazione della lega. 0.1 - 4.17% by weight of a metal or a combination of metals selected from a) gold and platinum, b) gold and palladium c) gold, platinum and palladium, d) platinum, e) palladium, and f) platinum and palladium; 0 - 0.5% by weight of one or more metals selected from iridium, germanium, silicon, osmium, tin, indium and gallium, preferably iridium, germanium, silicon and gallium; and the rest copper. It is to be understood that the alloys described therein may always contain other elements, ie elements that are not listed as compositional components of the alloy, in the form of traces in total quantities up to 0.2% by weight. These traces derive from raw material impurities or are residues of auxiliary materials used during the production or processing of the alloy.
Le aggiunte di metalli come gallio e/o indio aiutano ad abbassare il punto di fusione della lega. Per influenzare la fluidità del materiale fuso, l’adattamento del materiale alla microfusione, allo stampaggio (qui si usano preferibilmente leghe senza silicio) o alla saldatura (qui sono preferibili aggiunte di indio), l’esperto con le sue conoscenze generali varia le percentuali dei componenti ausiliari. La variazione del contenuto di rame rispetto a metalli con colorazione argentea, come per esempio lo zinco, l’argento e il palladio, permette la realizzazione di colorazioni diverse della lega che variano dal colore rosso, ovvero, rosa attraverso il colore di oro giallo fino a tonalità che corrispondono a quelle note per l’oro bianco. Additions of metals such as gallium and / or indium help to lower the melting point of the alloy. To influence the fluidity of the molten material, the adaptation of the material to investment casting, molding (preferably silicon-free alloys are used here) or welding (indium additions are preferable here), the expert with his general knowledge varies the percentages of auxiliary components. The variation of the copper content compared to metals with a silver color, such as zinc, silver and palladium, allows the creation of different colors of the alloy that vary from red, that is, pink through the color of yellow gold up to shades that correspond to those known for white gold.
Sorprendentemente, la bassa caratura di rispettivamente oro, platino e palladio permette realizzare leghe che imitano i colori dei rispettivi metalli preziosi o delle loro leghe e presentano contemporaneamente un’elevata lucentezza. Surprisingly, the low carat of gold, platinum and palladium respectively allows alloys to be made that mimic the colors of the respective precious metals or their alloys and at the same time have a high luster.
In più, la lega risulta molto elastica, di facile pulitura, lucidatura, lavorazione meccanica e presenta buoni valori di specchiatura, in parte migliori di altre leghe di caratura superiore, In addition, the alloy is very elastic, easy to clean, polish, mechanically work and has good mirroring values, partly better than other higher carat alloys,
In una variante vantaggiosa dell’invenzione, la lega non contiene gli elementi iridio, germanio, silicio, osmio, stagno, indio e gallio come elementi compositori della lega. Come detto sopra, li può comunque contenere all’interno del gruppo delle tracce di altri elementi. In an advantageous variant of the invention, the alloy does not contain the elements iridium, germanium, silicon, osmium, tin, indium and gallium as composing elements of the alloy. As mentioned above, it can still contain them within the group of tracks of other elements.
Le varianti di seguito descritte sono le composizioni che nella ricerca di leghe economiche a basse carature di metalli preziosi si sono rivelate particolarmente idonee per l’uso nella bigiotteria poiché sono poco ossidabili, facilmente lavorabili e lucide e imitano le tonalità delle leghe ad alta caratura. The variants described below are the compositions that in the search for low-carat low-carat precious metal alloys have proven to be particularly suitable for use in costume jewelery as they are not very oxidizable, easily workable and shiny and imitate the shades of high-grade alloys. carat.
