Embodiment 1

[0020] A silver alloy with blue luster and corrosion resistance for jewelry and its technology. In terms of weight percentage, the composition of the alloy is P:0.1wt.%, Mg:1.0wt.%, In:4.0wt.%, Co:3.2wt.%, Mo:0.4wt.%, Th:0.1wt.% , Ge: 1.5wt.%, the balance is silver. The above-mentioned silver alloy with blue luster and corrosion resistance and its technology for jewelry include the following steps: adding the raw materials in the above ratio into an induction furnace under an argon environment, and using a graphite crucible; melting at 1100 degrees Keep warm for 10 minutes, stir evenly by high-frequency induction furnace electromagnetically; after stirring evenly, keep warm at 1100 degrees for 1 minute and cast out of the furnace; alloy casting uses a steel mold with a diameter of 50-100mm, and uses water cooling to cool down. The ingot can be used as a casting raw material for casting in the subsequent process to prepare castings of complex shapes; the final heat treatment p...

Abstract

The invention discloses a jewelry silver alloy having blue gloss and corrosion resistance and a technology of the silver alloy. The alloy comprises compositions including, by weight, 0.1%-0.2% of P, 1.0%-1.2% of Mg, 4.0%-5.0% of In, 3.2%-4.8% of Co, 0.4%-0.6% of Mo, 0.1%-0.2% of Th, 1.5%-1.8% of Ge and the balance silver. A new type capable of having the blue gloss is provided for colorful silveron the market at present by means of the material, and in addition, the material further has the excellent color-changing-resistant characteristic. The production cost is reduced, and the related production technology and equipment meets are greatly simplified. It can be predicted that material implementation and industrialization can obtain plenteous economic gains and social benefits.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a silver alloy. Background technique [0002] Silver is a metal with a very strong white luster. In English, silver is called Silver, which means white brilliance. Sterling silver has a soft texture and good ductility. It can be made into various ornaments through drawing, hammering and other processing techniques. It was an indispensable jewelry material in ancient times. The history of human use of silver can be traced back to about 3000 BC, and silver utensils were found in the Mesopotamia civilization in Southwest Asia. In nature, it seldom exists in the form of simple substance, and generally exists in the form of compound in deep veins, which is difficult to extract, so the discovery and utilization of silver is later than that of gold. [0003] Because of its beauty and rarity, silver has become a symbol of wealth and status. Silver coins are an important currency in cir...
