Definitions

  • the present invention relates to a metal alloy for jewels and similar products, for example watches, pens, tableware, cutlery, knick-knack and other gift items.
  • the present invention also relates to jewels and similar products manufactured with said alloy.
  • the gold-like metals used for manufacturing jewels and similar products generally consist of metal alloys, in particular containing silver, which are coated with a thin gold layer applied by means of plating processes. These known materials are relatively expensive due to the plating and to the employed amount of gold, even if small. Furthermore, said gold layer tends to deteriorate after a determinate time, due to the mechanical wear and tear of the product surface.
  • the alloy according to the present invention allows to obtain a material which is similar to gold, but can be manufactured in a simple and economic manner and keeps substantially unaltered its outer aspect during the time.
  • different color gradations of gold can be reproduced with the alloy according to the present invention by suitably changing the percentages of silver, copper and zinc, if present.
  • the metal alloy according to the present invention comprises silver in a percentage A comprised between 30% and 70%, as well as copper in a percentage B comprised between 30% and 70%.
  • Other metals can be present in a percentage comprised between 0% and 16%, in particular zinc in a percentage C comprised between 3% and 13%.
  • the alloy according to a first embodiment of the present invention comprises silver in a percentage A comprised between 35% and 45%, in particular between 39,5% and 40,5%, and copper in a percentage B comprised between 55% and 65%, in particular between 59,5% and
  • the alloy according to a second embodiment of the present invention comprises silver in a percentage A comprised between 55% and 65%, in particular between 58% and 59%, and copper in a percentage B comprised between 35% and 45%, in particular between 41% and 42%.
  • the alloy according to a third embodiment of the present invention comprises silver in a percentage A comprised between 35% and 45% and copper in a percentage B comprised between 48% and 61%, as well as zinc.
  • this alloy comprises silver in a percentage A comprised between 39,5% and 40,5%, copper in a percentage B comprised between 48% and 56%, as well as zinc in a percentage C comprised between 5% and 12%.
  • the alloy according to a fourth embodiment of the present invention comprises silver in a percentage A comprised between 55% and 65% and copper in a percentage B comprised between 32% and 40%, as well as zinc.
  • this alloy comprises silver in a percentage A comprised between 58% and 59%, copper in a percentage B comprised between 32% and 38%, as well as zinc in a percentage C comprised between 4% and 9%.
