Definitions

  • the present invention relates to a gold alloy gray nickel free comprising 75-76% by weight of Au and between 12 and 14% by weight of Pd.
  • the nickel allergy problem has leads to the limitation, even to the total prohibition of the presence of nickel in white or gray gold alloys. In more, these alloys are excessively hard and not very deformable so they don't lend themselves well to work in the jewelry and watchmaking in particular.
  • CH-684 616 has already proposed a gold alloy nickel-free gray with good deformability, comprising generally in this case essentially between 15% and 17% by weight of Pd, between 3 and 5% of Mn and between 5 and 7% in Cu weight.
  • Pd is a very expensive metal and whose prices fluctuate enormously.
  • the lowering of the proportion of Pd, and the addition of Ag in the above-mentioned alloy leads to low deformability.
  • a percentage too high Ag causes tarnishing of the alloy.
  • JP-A-9078160 has also proposed a ternary gray gold alloy with more than 10% by weight of Pd and more than 10% by weight of Cu, the amounts of Pd and Cu preferably being the same, which means that the higher the the higher the Pd content, the higher the copper content and vice versa.
  • a ternary gray gold alloy with more than 10% by weight of Pd and more than 10% by weight of Cu, the amounts of Pd and Cu preferably being the same, which means that the higher the higher the Pd content, the higher the copper content and vice versa.
  • the respective contents of Pd and Cu can only be 12.5% respectively.
  • such a ternary alloy does not not in particular the molding properties, allowing its use with the technique known as lost wax.
  • JP 03 130 333 A has also proposed an alloy white gold comprising between 10 and 35% by weight of Pd to which is added Ga and In in order to improve the flowability properties and to make it easier to to work.
  • this alloy contains between 1 and 10% in weight of Ag intended to reduce the proportion of Pd.
  • the addition of Ag in such an alloy causes tarnishing of its color.
  • the object of the present invention is to substantially improve white or gray gold alloys allowing reduce the proportion of Pd without reducing its properties deformability, as well as its metallurgical properties allowing it to be used in casting techniques by lost wax.
  • this invention relates to an alloy nickel-free gray gold according to claim 1.
  • Some other items are added to the items main of this alloy, to improve its properties metallurgical, in particular to lower its temperature melting, improving the fineness of grain as well as for avoid porosities.
  • the table gives indications relating to the hardness of the alloy in the molded annealed and work-hardened state, as well as color measured in a three-axis coordinate system.
  • examples 2, 3, 4 show a relatively low deformability, so these alloys do not lend themselves to applications where good deformability is required.
  • Examples 4, 8, and 11 show saturation in yellow expressed by the value b * relatively high, compared to references and other alloys of the same category, i.e. including between 12 and 14% Pd.
