Embodiment 1
[0018] 958 silver alloy with blue luster and anti-fading and its process for jewelry. In terms of weight percentage, the composition of the alloy is P:0.2wt.%, Sr:0.5wt.%, Mo:0.6wt.%, Ir:0.2wt.%, Co:1.0wt.%, In:0.3wt.%. , Ag: 95.0wt.%, the balance is copper. The above-mentioned 958 silver alloy with blue luster and anti-fading 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; heat preservation at 1200 degrees during melting 10 minutes, rely on high-frequency induction furnace to stir evenly; after stirring evenly, keep warm at 1200 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. Roll the obtained ingot at room temperature, and the amount of rolling in each pass is 20-30%; after every two rollings, the intermediate annealing temperature is 520 degrees, and the ...
