Embodiment 1
[0016] A corrosion-resistant and deformation-resistant 10K rose red gold containing Ba and Ge gold alloy. In terms of weight percentage, the composition of the alloy is Ba:0.3wt.%, Zr:0.2wt.%, Ge:1.0wt.%, W:0.3wt.%, Ag:20.0wt.%, Au:40.0wt.% , and the balance is copper. The preparation method of the above-mentioned corrosion-resistant and deformation-resistant 10K rose gold alloy containing Ba and Ge includes the following steps: adding the raw materials in the above ratio into an induction furnace protected by argon gas, and using a graphite crucible; The flow of argon is protected to avoid severe burning of the alloy elements due to the large air flow; when smelting, it is kept at 1150 degrees for 10 minutes, and it is evenly stirred by a high-frequency induction furnace; after stirring, it is kept at 1250 degrees for 1 minute and cast out of the furnace; gold alloy Casting adopts a steel mold with a diameter of 100-200mm, and uses water cooling to cool down. Roll the obtai...
