Description

  

  Alliage destiné notamment à remplacer le doublé et le dorage en horlogerie  et en bijouterie.    La     présente    invention a pour objet un  alliage destiné notamment à remplacer le  doublé et le dorage en horlogerie et en bijou  terie, caractérisé par le fait qu'il contient au  moins trois des quatre métaux or, palladium,       cuivre    et aluminium, dans une proportion en  poids comprise entre 2 et 5 % d'or, jusqu'à  o,3% de palladium, entre 87,5 et<B>90%</B> de  cuivre et entre 5 et     7,5%    d'aluminium.  



       Les    métaux composants sont fondus dans  le vide dans l'ordre or, palladium, cuivre et  aluminium; l'alliage     obtenu    est     ensuite    coulé  dans le vide en barres ou en lingots     qu'on     travaille     ensuite    comme un autre     métal.     



  La fonte et lai coulée s'effectuent dans le  vide afin d'éviter l'action particulièrement       nuisible    que pourrait avoir l'air sur le cuivre.  L'addition de     palladium    augments la     résis-          tanee,de    l'alliage à l'oxydation.  



  1 kg d'alliage     .destiné    notamment à la;  fabrication des bracelets et boîtes de montres  pour montres-bracelets peut, par exemple,  être préparé en fondant successivement dans  le vide 49 g d'or, 1 g de palladium, 875 g  de cuivre auxquels on ajoute 75 g d'alumi  nium.  



  On peut, par exemple, préparer 1 kg  d'alliage .destiné notamment à la fabrication  de bijoux pour dames, y compris     les    bracelets,  en fondant successivement dans le vide 25 g  d'or, 1 g de palladium, 899 g de cuivre, aux  quels on ajoute 75 g d'aluminium.  



  Si l'on n'a pas à craindre particulièrement  l'effet de l'oxydation     sur    l'alliage à préparer,    on pourra     supprimer    le palladium et répar  tir le poids     relatif    à ce composant sur les  trois autres métaux restants.  



  L'alliage     obtenu    est brillant, résistant à       l'action    -de l'air, très léger par     rapport    à l'or,  possède un point de fusion élevé, et il est, de  plus, facile à travailler comme l'or et bon  marché.



  Alloy intended in particular to replace lining and gilding in watchmaking and jewelry. The present invention relates to an alloy intended in particular to replace doubling and gilding in watchmaking and jewelry, characterized in that it contains at least three of the four metals gold, palladium, copper and aluminum, in a proportion of weight between 2 and 5% gold, up to 0.3% palladium, between 87.5 and <B> 90% </B> copper and between 5 and 7.5% aluminum.



       The component metals are melted in a vacuum in the order of gold, palladium, copper and aluminum; the alloy obtained is then cast in a vacuum into bars or ingots which are then worked like another metal.



  Melting and casting are carried out in a vacuum in order to avoid the particularly harmful action which the air could have on the copper. The addition of palladium increases the resistance of the alloy to oxidation.



  1 kg of alloy. Intended in particular for; manufacture of bracelets and watch cases for wristwatches can, for example, be prepared by successively melting in vacuum 49 g of gold, 1 g of palladium, 875 g of copper to which is added 75 g of aluminum.



  One can, for example, prepare 1 kg of alloy. Intended in particular for the manufacture of ladies' jewelry, including bracelets, by successively melting in vacuum 25 g of gold, 1 g of palladium, 899 g of copper, to which is added 75 g of aluminum.



  If one does not have to particularly fear the effect of the oxidation on the alloy to be prepared, one can remove the palladium and repair the relative weight of this component on the three other remaining metals.



  The alloy obtained is bright, resistant to the action of air, very light compared to gold, has a high melting point, and it is, moreover, easy to work like gold and good. market.
