Embodiment 1
[0020] A silver alloy resistant to hydrogen sulfide corrosion and excellent die-casting properties for jewelry. In terms of weight percentage, the composition of the alloy is B: 0.1wt.%, Ca: 1.2wt.%, Al: 2.0wt.%, Ni: 1.6wt.%, In: 3.0wt.%, Ge: 1.0wt.%. , Sn: 1.5wt.%, the balance is silver. The above-mentioned a kind of silver alloy that is corrosion-resistant to hydrogen sulfide and has excellent die-casting performance for jewelry comprises the following steps: adding the above proportioned raw materials into an induction furnace under an argon environment, and adopting a graphite crucible; 10 minutes, rely on high-frequency induction furnace to stir evenly; 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...
