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. The hardness is generally soft, and the Vickers hardness is GB / T4340.1-1999 is about 72.4HV1; Rockwell hardness GB / T230.1-2009 is about 68.9HRF; density GB / T1423-1996 is about 19.352g / cm3, so pure gold products are easy to deform and are not suitable for inlaid jewelry
In addition, the color of thousand pure gold is yellow, and the color is relatively monotonous.

Embodiment approach 1

[0017] The gold alloy provided by Embodiment 1, its components are expressed in parts by weight, and consist of the following substances:

[0018] 90 parts of gold, 1-10 parts of platinum or palladium, 1-10 parts of silver, 1-10 parts of copper or bronze, and 1-10 parts of zinc.

[0019] Embodiment one enumerates the embodiment below and illustrates:

Embodiment 1

[0021] The gold alloy provided by Embodiment 1 of the present invention consists of the following substances:

[0022] 90 points of gold, 0.5 parts of platinum, 1.0 parts of silver, 8 parts of copper, and 0.5 parts of zinc.

[0023] The gold alloy that this embodiment one provides, the weight percent of each component is:

[0024] Gold accounts for 90%, platinum accounts for 0.5%, silver accounts for 1.0%, copper accounts for 8%, and zinc accounts for 0.5%.

[0025] In the embodiment of the present invention, by adding platinum, red copper, silver, and zinc to gold, the color of gold is changed, so that the color of the obtained gold alloy appears rose red, which increases the fashion sense compared with the traditional yellow; in addition, After testing, the Rockwell hardness GB / T230.1-2009 of the gold alloy provided in this example is about 60.88HRB, the Vickers hardness GB / T4340.1-2009 is about 184.15HV1, and the density GB / T1423-1996 is about 17.184g / cm3, It can be seen ...

Abstract

The invention provides gold alloy and a preparation method thereof. The gold alloy comprises the following components in parts by weight: 90 parts of gold, 1-10 parts of platinum or palladium, 1-10 parts of silver, 1-10 parts of pure copper or bronze and 1-10 parts of zinc. The Rockwell hardness GB / T230.1-2009 of the gold alloy is about 60.88 HRB, the Vickers hardness GB / T4340.1-2009 is about 184.15HV1, and the density GB / T1423-1996 is about 17.184g / cm<3>, thus the hardness of the gold alloy is higher than that of the thousand pure gold, and the hardness of the gold alloy is improved.

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. The hardness is generally soft, and the Vickers hardness is GB / T4340.1-1999 is about 72.4HV1; Rockwell hardness GB / T230.1-2009 is about 68.9HRF; density GB / T1423-1996 is about 19.352g / cm3, so pure gold products are easy to deform and are not suitable for setting jewelry. In addition, the color of thousand pure gold is yellow, and the color is relatively monotonous. [0003] In the prior art, inlaid jewelry is usually made of 18K gold or platinum. 18K gold is made by adding about 25% of silver, copper, zinc and other metals into gold. 18K gold is harder than pure gold, but its gold content is only 75%. ....
