Embodiment 1

[0016] A corrosion-resistant and deformation-resistant 10K rose red gold containing Ba and Ge gold alloy. In terms of weight percentage, the composition of the alloy is Ba:0.3wt.%, Zr:0.2wt.%, Ge:1.0wt.%, W:0.3wt.%, Ag:20.0wt.%, Au:40.0wt.% , and the balance is copper. The preparation method of the above-mentioned corrosion-resistant and deformation-resistant 10K rose gold alloy containing Ba and Ge includes the following steps: adding the raw materials in the above ratio into an induction furnace protected by argon gas, and using a graphite crucible; The flow of argon is protected to avoid severe burning of the alloy elements due to the large air flow; when smelting, it is kept at 1150 degrees for 10 minutes, and it is evenly stirred by a high-frequency induction furnace; after stirring, it is kept at 1250 degrees for 1 minute and cast out of the furnace; gold alloy Casting adopts a steel mold with a diameter of 100-200mm, and uses water cooling to cool down. Roll the obtai...

Abstract

The invention discloses a Ba and Ge containing gold alloy for corrosion-resisting and deformation-resisting 10K rose red gold. According to the weight percent, the alloy comprises components including0.3 wt.%-0.5 wt.% of Ba, 0.2 wt.%-0.4 wt.% of Zr, 1.0 wt.%-1.5 wt.% of Ge, 0.3 wt.%-0.5 wt.% of W, 20.0 wt.%-25.0 wt.% of Ag, 40.0 wt.%-42.0 wt.% of Au and the balance Cu. The Ba and Ge containing gold alloy avoids the phenomenon that current 10K rose gold fades in the usage process. Through alloy component innovation and optimization, the development bottleneck of jewelry 10K rose gold materialsis broken through. It can be predicted that abundant economic gains and social benefits can be obtained due to material implementation and industrialization.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a gold alloy. Background technique [0002] Gold has a wide range of applications, and has a wide range of applications in electronics, communications, aerospace, chemical, medical and other departments and people's daily life. Jewelry gold is an important application field of gold. In addition to the reasons for gold to preserve value, clarity and pleasing colors are also an important factor. For gold alloys, except for white gold, others are called colored gold. The most common color in life is 18K gold, and K is an international symbol used to represent the purity of gold. 18K gold refers to gold with a gold content of 75%, while the remaining 25% is composed of other metals in a certain proportion. The reason for the color is due to the different proportions of the metals. Many gold alloys have these effects, such as gold-nickel alloys, gold-indium alloys, gold-copper all...
