Definitions

  • the invention relates to a bronze alloy containing copper and tin, particularly for the manufacture of ornaments such as jewellery, jewellery, clocks and clock cases.
  • Such bronze alloys are known for good strength and workability. It is customary to add a wide range of other metals and elements such as aluminum, lead, manganese, silicon, beryllium, phosphorus, magnesium or cadmium as alloying elements in order to achieve desired requirements and/or a desired appearance.
  • the object of the invention is to create a bronze alloy of the type mentioned at the outset that is easy to cast, that is resistant to corrosion and sea water and is dermatologically harmless, has a delayed tarnish and has an independent warm color tone.
  • the bronze alloy contains gold as a further alloy component, the The proportion of tin is between 6 and 8 percent by weight and the proportion of gold is between 11.5 and 13.5 percent by weight.
  • alloy components not only achieve the required properties, but also create a material with a consistent value thanks to the gold component.
  • the tin content is 7% by weight and the gold content is 12.5% by weight.
  • the high purity of the bronze alloy with these three components makes it particularly skin-friendly. This means that pieces of jewelery made from this bronze alloy can be worn particularly comfortably on a person's skin without causing irritation and which has a high degree of body compatibility.
  • Weight percent of the bronze alloy which leads to a particularly high level of body compatibility, since only non-toxic metals are used.
  • a particularly high level of body compatibility is achieved if the copper component of the bronze alloy has a degree of purity of > 99.99 and is therefore a metal of the highest purity.
  • a particularly high level of body compatibility is also achieved if the tin component of the bronze alloy has a degree of purity of > 99.99 and is therefore a metal of the highest purity.
  • the gold component of the bronze alloy has a degree of purity of > 99.99 and is therefore a metal of the highest purity.
