Abstract

The invention relates to the technical field of alloys, and particularly relates to a gold alloy. The gold alloy comprises 5-10% of Ag, 3-7% of Zn, 2-5% of Cu, 2-4% of Nb, 0.5-1.5% of Ca, 0.5-1.5% of Zr, 2-4.5% of Er, 0.5-1% of Ho, 1-3% of epoxy resin and the balance of gold and inevitable impurities. The invention also provides a synthetic method of the gold alloy. The gold alloy provided by the invention has the advantages of excellent high-temperature property, very long service life, high-temperature resistance, oxidization resistance and creep resistance; gold jewelry made from the gold alloy has the advantages of low price, high hardness and long-lasting color and luster and can be worn for a long time.

Description

technical field [0001] The invention belongs to the technical field of alloys, and particularly relates to a gold alloy. Background technique [0002] Gold alloy has a long history as a material for the traditional production of gold jewelry. Usually, the gold alloy used in pure gold jewelry is 99.99% gold with 0.09% Cu or Ag metal added. The hardness is generally soft, so pure gold The product is easy to deform and is not suitable for inlaid jewelry. In addition, the color of pure gold is yellow, which is not fashionable enough today when white jewelry is popular. Therefore, common jewelry is made of 18K or 14K gold with a gold content of 75%. 25% of a piece of 18K gold jewelry is Ni, Cu, Zn, Ag and other metals, 14K gold jewelry contains more than 58.33% gold elements, and the rest are Cu, Zn, Ag and other metals. Compared with 18K gold, 14K gold can be mixed with more other elements, which can adjust different colors, high hardness, various processing of inlaid gemstones...
