Problems solved by technology

It is obviously not suitable for the field of Miao silver that requires low price
In addition, although a layer of colored film can be plated on the surface of Miao silver jewelry by ion plating, this colored film will inevitably expose the fresh matrix alloy due to corrosion, fading or wear after use, resulting in vulcanization. further deterioration of corrosion
[0008] But it is a pity that Miao silver alloy has not formed a rich color silver series like color K gold.

Embodiment 1

[0019] A corrosion-resistant yellow seedling silver alloy with low density and light weight and its technology. In terms of weight percentage, the composition of the alloy is Li:0.8wt.%, Al:3.0wt.%, Mg:4.0wt.%, B:0.4wt.%, Sc:0.5wt.%, Zn:10.0wt.% , Ag: 30.0wt.%, the balance is copper. The above-mentioned low-density and light-weight corrosion-resistant yellow seedling silver alloy and its process include the following steps: adding the above-mentioned raw materials into an induction furnace under an argon environment, and using a graphite crucible; melting at 1400 degrees Keep warm for 10 minutes, stir evenly with high-frequency induction furnace electromagnetically; after stirring evenly, keep warm at 1400 degrees for 1 minute and cast out of the furnace; alloy casting uses a steel mold with a diameter of 20-30mm, and uses water cooling to cool down. The obtained ingot is rolled at room temperature, and the amount of reduction in each pass is 20-30%; after every two rollings,...

Abstract

The invention discloses a yellow Miao silver alloy with the features of low density, light weight and corrosion resistance, and a technology thereof. The yellow Miao silver alloy comprises, by weight,0.8%-1.2% of Li, 3.0%-4.0% of Al, 4.0%-6.0% of Mg, 0.4%-0.6% of B, 0.5%-0.8% of Sc, 10.0%-15.0% of Zn, 30.0%-50.0% of Ag and the balance copper. According to the yellow Miao silver alloy, a light-weight selection scheme is provided for Miao silver alloy in China, and the obtained product not only has excellent yellow appearance, but also is extremely resistant to hydrogen sulfide corrosion. The requirements of product update of the jewelry industry and the industry upgrade in China can be promoted through the implementation and industrialization of the yellow Miao silver alloy effectively.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a silver alloy. Background technique [0002] Wearing a silver crown, a silver necklace around the neck, and a chest full of silver ornaments, the image of a Miao girl in full attire constitutes the impression of the Miao people in most people's minds. As early as the Qing Dynasty, the use of silver jewelry by the Miao people was very common. Miao people, regardless of gender, old or young, regarded wearing silver jewelry as beautiful. In terms of the use of silver ornaments, southeast Guizhou is the heaviest, and there are many kinds of silver ornaments in Taijiang, Kaili, Leishan and other regions, and there are even more than 50 kinds of silver ornaments in full decoration. The girls in Miao Village are dressed in silver ornaments, the ornaments can reach half a person's height, and the parts can reach hundreds of pieces, weighing more than 20 to 30 catties. This complicated ...
