Embodiment 1

[0017] The jewelry material is made of 18K white gold material and processing technology that is resistant to wear and nickel allergy. By weight percentage, the composition of the alloy is Ca: 0.8wt.%, Re: 0.2wt.%, Fe: 0.6wt.%, Ge: 2.0wt.%, In: 8.0wt.%, Ag: 10.0wt.% , the balance is gold. The above-mentioned wear-resistant and nickel-allergic-free 18K white gold material for jewelry materials and a preparation method for the processing technology include the following steps: adding the raw materials in the above proportions into an argon-protected induction furnace, and using a graphite crucible; after the metal is melted, using Low-flow argon protection to avoid serious burning of alloy elements due to large airflow; keep at 1200 degrees for 10 minutes during smelting, and stir evenly by high-frequency induction furnace; The alloy casting adopts a steel mold with a diameter of 50-100mm, and it is cooled by water cooling. The obtained ingot is rolled at room temperature, and...

Abstract

The invention discloses a wear-resistant nickel-allergy-free 18K platinum material for jewelry and a processing technology thereof. The alloy comprises following components in percentage by weight: 0.8 to 1.0 wt.% of Ca, 0.2 to 0.4 wt.% of Re, 0.6 to 1.4 wt.% of Fe, 2.0 to 3.0 wt.% of Ge, 8.0 to 10.0 wt.% of In, 10.0 to 12.0 wt.% of Ag, and the balance being gold. The provided K14 platinum does not contain nickel, which is allergic to human body and is usually contained by platinum alloy in the prior art. The provided K14 platinum does not contain any nickel, is friendly to human body, and isdeveloped by optimizing the components. The bottleneck of the jewelry field is broken through effectively. The application and industrialization of the K14 platinum may generate great economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a gold alloy. Background technique [0002] Gold is a precious metal and one of the earliest metals discovered and exploited by human beings. It is an important raw material for making jewelry and coins, and an important reserve material for the country. It is known as the king of metals. It is not only regarded as a symbol of beauty and wealth, but also benefits human life with its unique value. An important area of ​​application for gold is decorative materials, including jewelry. Gold can also be used for daily necessities, such as gold-plated clocks, belt buckles, lighters, pens, etc. The watch kingdom of Switzerland is not a big country, but its jewelry industry uses about 40 tons of gold every year, of which 95% is used in the watchmaking industry. A single watch factory in Japan consumes 1 ton of gold salt a year, which is equivalent to 680 kilograms of gold. Gold is u...
