Embodiment 1

[0017] A white, low-density, high-hardness, corrosion-resistant, low-gold content Miao gold alloy and its process. In terms of weight percentage, the composition of the alloy is Li: 0.4wt.%, Al: 15.0wt.%, In: 10.0wt.%, B: 0.5wt.%, Y: 0.2wt.%, Ge: 4.0wt.% , Au: 29.0wt.%, the balance is copper. The above-mentioned white, low-density, high-hardness, corrosion-resistant, low-gold content Miao gold alloy and its process include the following steps: adding raw materials with the above proportion into an induction furnace under an argon atmosphere, and using a graphite crucible; smelting at 1200 The temperature is kept for 10 minutes, and the high-frequency induction furnace is used to stir evenly; after stirring, the temperature is kept at 1200°C for 1 minute and cast out; the alloy casting adopts a steel mold with a diameter of 20-30mm and is cooled by water. The resulting ingot is rolled at room temperature, and the amount of each pass is 20-30%; the intermediate annealing tempera...

Abstract

The invention discloses a white low-density high-hardness corrosion-resistant low-gold-content gold alloy for Miao people and a process of the gold alloy. The gold alloy comprises 0.4-0.8 wt.% of Li,15.0-18.0 wt.% of Al, 10.0-12.0 wt.% of In, 0.5-0.8 wt.% of B, 0.2-0.3 wt.% of Y, 4.0-6.0 wt.% of Ge, 29.0-30.0 wt.% of Au and the balance Cu. The material provides a lightweight option for the gold alloy of Miao people in China. Obtained products have not only excellent white appearance but also good corrosion resistance. The implementation and industrialization of the material can effectively boost the demand of product update and industry upgrade in the jewelry industry in China.

Description

Technical field [0001] The invention relates to the technical field of alloys, in particular to a gold alloy. Background technique [0002] The Miao people love silver jewelry, and the description of the Miao people wearing silver jewelry comes from the Ming Dynasty. Today, the wearing of silver jewelry has become a materialized expression of Miao culture. The distinction of silver jewellery between splendid and casual clothes divides the sacred and secular dual space of the Miao people. According to the Miao people, it means "no girl without silver or flowers, and clothes without silver cannot make costumes." In the grand festivals and important ceremonial occasions of the Miao nationality, silver costumes are the admission ticket for women. In any seemingly simple living habits, there are extremely deep cultural traditions. The Miao costumes with silver ornaments as an important part are also called "historical books worn on the body". There are also many passages in ancie...
