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.

Abstract

The invention discloses a light high-strength blue Miao silver alloy with excellent pressure casting performance and a process thereof. The light high-strength blue Miao silver alloy is prepared from,by weight percent, 0.5 wt% to 0.8 wt% of Sr, 5.0 wt% to 8.0 wt% of Al, 2.0 wt% to 3.0 wt% of Mg, 0.5 wt% to 0.8 wt% of Be, 4.0 wt% to 5.0 wt% of Co, 12.0 wt% to 15.0 wt% of In, 30.0% to 50.0 wt% of Ag and the balance copper. According to the material, a weight-reducing selecting scheme is provided for the Miao silver alloy in our country, the obtained product has an excellent blue impression, andis extremely resistant to hydrogen sulfide corrosion. The needs of product updating and industry upgrading of the jewelry industry in our country can be effectively promoted through implementation and industrialization of the material.

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 ...
