Description

Technical field [0001] The invention relates to the technical field of alloys, in particular to a silver alloy. Background technique [0002] Among jewelry alloys, gold alloys are the most important. The market demand for gold alloys for jewelry has expanded rapidly in the jewelry market in recent years, which indirectly illustrates the important position of gold jewelry in the world's jewelry industry. This is largely due to the beautiful color of gold, long-term storage without discoloration, and good processing properties. Although there are many types of gold alloys used in jewelry, and the appearance of color is changeable, the most eye-catching is the gold alloy for jewelry called Span gold. [0003] Spangold uses the martensite in the gold alloy or the surface relief and fine layered structure produced by the martensite transformation to produce the grating barrier diffraction effect under the action of light, so that the surface of the gold alloy can produce similar Beca...
