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 / T230.1-2004 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 pure gold is yellow, which is not fashionable enough today when white jewelry is popular.

Embodiment approach 1

[0028] The gold alloy provided by Embodiment 1, its components are expressed in parts by weight, and consist of the following substances:

[0029] 90 parts of gold, 1-10 parts of platinum or palladium, 1-10 parts of nickel, 1-10 parts of silver, and 1-10 parts of zinc.

[0030] Embodiment one enumerates the embodiment below and illustrates:

Embodiment 1

[0032] The gold alloy provided by Embodiment 1 of the present invention consists of the following substances:

[0033] 90 points of gold, 1 part of platinum, 6 parts of nickel, 1.8 parts of silver, and 1.2 parts of zinc.

[0034] The gold alloy that this embodiment one provides, the weight percent of each component is:

[0035] Gold accounts for 90%, platinum accounts for 1%, nickel accounts for 6%, silver accounts for 1.8%, and zinc accounts for 1.2%.

[0036] In the embodiment of the present invention, the gold is bleached by adding platinum, nickel, silver, and zinc to the gold, so that the color of the obtained gold alloy appears white, which increases the fashion sense compared with the traditional yellow; in addition, after testing, The gold alloy Rockwell hardness GB / T230.1-2004 provided by this embodiment is about 82.5HRG, the Vickers hardness GB / T4340.1-1999 is about 227HV10, and the density GB / T1423-1996 is about 17.28g / cm3. The Vickers hardness of gold GB / T4340.1-...

Abstract

The invention provides a gold alloy and a preparation method thereof, wherein the gold alloy comprises the following components by weight portion as: 90 portions of gold, 1 to 10 portions of platinum or palladium, 1 to 10 portions of nickel, 1 to 10 portions of silver and 1 to 10 portions of zinc. The invention can enhance the hardness of the gold alloy and change the color of the gold alloy while ensuring that the gold amount of the alloy is higher than 90 percent.

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 / T230.1-2004 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 pure gold is yellow, which is not fashionable enough today when white jewelry is popular. [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 con...
