Embodiment 1
[0017] The jewelry material is made of 18K white gold material and processing technology that is resistant to wear and nickel allergy. By weight percentage, the composition of the alloy is Ca: 0.8wt.%, Re: 0.2wt.%, Fe: 0.6wt.%, Ge: 2.0wt.%, In: 8.0wt.%, Ag: 10.0wt.% , the balance is gold. The above-mentioned wear-resistant and nickel-allergic-free 18K white gold material for jewelry materials and a preparation method for the processing technology include the following steps: adding the raw materials in the above proportions into an argon-protected induction furnace, and using a graphite crucible; after the metal is melted, using Low-flow argon protection to avoid serious burning of alloy elements due to large airflow; keep at 1200 degrees for 10 minutes during smelting, and stir evenly by high-frequency induction furnace; The alloy casting adopts a steel mold with a diameter of 50-100mm, and it is cooled by water cooling. The obtained ingot is rolled at room temperature, and...
