Problems solved by technology

[0002] Gold alloy has a long history as a traditional material for producing gold jewelry. Usually, the gold alloy used in pure gold jewelry is 99.99% gold with 0.09% silver or copper added, and its gold content is at least 99.9%. The hardness is generally soft, the Vickers hardness GB / T4340.1-1999 is about 72.4HV1, the Rockwell hardness GB / T230.1-2004 is about 68.9HRF, and the density GB / T1423-1996 is about 19.352g / cm3, so the pure gold product is easy It is deformed and is not suitable for setting jewelry; moreover, the color of pure gold is yellow, which is not fashionable enough in today's rose-colored jewelry; in addition, the preparation cost of pure gold is relatively high due to its high gold content

Embodiment approach 1

[0016] The gold alloy provided by Embodiment 1, its components are expressed in parts by weight, and consist of the following substances:

[0017] 60-70 parts of gold, 0.5-2 parts of palladium, 1-2 parts of ruthenium, 12-14 parts of silver, 3-5 parts of zinc, 0.5-2 parts of aluminum, 10-15 parts of red copper or bronze.

[0018] Embodiment one enumerates the embodiment below and illustrates:

Embodiment 1

[0020] The gold alloy provided by Embodiment 1 of the present invention consists of the following substances:

[0021] 66.66 parts of gold, 1 part of palladium, 1 part of ruthenium, 14 parts of silver, 4 parts of zinc, 1 part of aluminum, 12.34 parts of copper or bronze.

[0022] The gold alloy that this embodiment one provides, the weight percent of each component is:

[0023] Gold accounted for 66.66%, palladium 1.0%, ruthenium 1.0%, silver 14.0%, zinc 4.0%, aluminum 1.0%, and copper or bronze 12.34%.

[0024] In the embodiment of the present invention, the gold is changed in color by adding palladium, ruthenium, silver, zinc, aluminum, and copper to the gold, so that the color of the obtained gold alloy appears rose red, which increases the fashion compared to the traditional yellow. In addition, after testing, the Rockwell hardness GB / T230.1-2009 of the gold alloy provided by the present embodiment is about 79.78HRB, the Vickers hardness GB / T4340.1-2009 is about 171.16HV1...

Embodiment 2

[0027] 66.66 parts of gold, 1 part of palladium, 2 parts of ruthenium, 13 parts of silver, 3 parts of zinc, 1 part of aluminum, 13.34 parts of copper or bronze.

Abstract

The invention provides a gold alloy and a method for preparing the same, wherein the gold alloy comprises the components of, by weight, 60 to 70 parts of gold, 0.5 to 2 parts of porpezite, 1 to 2 parts of ruthenium, 12 to14 parts of silver, 3 to 5 parts of zinc, 0.5 to 2 parts of aluminum and 10 to 15 parts of pure copper or bronze. The gold alloy and the method for preparing the same can improve the hardness of the gold alloy, change the color of the gold alloy and reduce the preparation cost of the gold alloy.

Description

technical field [0001] The invention relates to the technical field of precious metal processing, in particular to a gold alloy and a preparation method thereof. Background technique [0002] Gold alloy has a long history as a traditional material for producing gold jewelry. Usually, the gold alloy used in pure gold jewelry is 99.99% gold with 0.09% silver or copper added, and its gold content is at least 99.9%. The hardness is generally soft, the Vickers hardness GB / T4340.1-1999 is about 72.4HV1, the Rockwell hardness GB / T230.1-2004 is about 68.9HRF, and the density GB / T1423-1996 is about 19.352g / cm3, so the pure gold product is easy It is deformed and is not suitable for inlaid jewelry; moreover, the color of pure gold is yellow, which is not fashionable enough in today's rose-colored jewelry; in addition, due to the high gold content of pure gold, its preparation cost is also high. Contents of the invention [0003] The problem to be solved by the present invention is ...
