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 white jewelry; in addition, due to the high gold content, the preparation cost of pure gold is also high

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 platinum, 0.5-1 part of palladium, 11-17 parts of silver, 1-6 parts of zinc, 1-3 parts of nickel, and 11-14 parts of copper .

[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, 0.8335 parts of platinum, 0.8335 parts of palladium, 13.336 parts of silver, 3.334 parts of zinc, 1.667 parts of nickel, and 13.336 parts of copper.

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

[0023] Gold accounts for 66.66%, platinum accounts for 0.8335%, palladium accounts for 0.8335%, silver accounts for 13.336%, zinc accounts for 3.334%, nickel accounts for 1.667%, and copper accounts for 13.336%.

[0024] In the embodiment of the present invention, by adding platinum, palladium, silver, zinc, nickel, and copper to the gold, the color of the gold is changed, so that the color of the obtained gold alloy appears white, which increases the sense of fashion compared to the traditional yellow After testing, the Rockwell hardness GB / T230.1-2009 of the gold alloy provided in this embo...

Abstract

The invention provides a gold alloy and a preparation method thereof. The gold alloy comprises the following components by weight part: 60 to 70 parts of gold, 0.5 to 2 parts of platinum, 0.5 to 1 part of palladium, 11 to 17 parts of silver, 1 to 6 parts of zinc, 1 to 3 parts of nickel, and 11 to 14 parts of copper. According to the embodiment of the invention, the hardness of the gold alloy can be improved, the color of the gold alloy can be changed, and the preparation cost of the gold alloy can be reduced.

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 inlaying jewelry; moreover, the color of pure gold is yellow, which is not fashionable enough in today's white jewelry; in addition, the preparation cost of pure gold is relatively high due to its high gold content. Contents of the invention [0003] The problem to be solved by the present invention is ...
