【発明の詳細な説明】
［産業上の利用分野］
本発明は、指輪、ネックレス、ブローチ、ネクタイ止め
その他装身具として用いられる板や線などの加工材ある
いは鋳造体に使用する装飾用Ａｕ合金に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a decorative Au alloy used for processed materials or cast bodies such as plates and wires used as rings, necklaces, brooches, tie holders, and other accessories.
［従来の技術］
Ａｕは、Ｃｕと共に数少ない有色金属の一つであり、そ
の美しい黄金色と加工し易さの故に古くから装身具とし
て使用されている。しかし、そのままでは軟らかすぎる
ため、一般にはＡｇ、ＣｕおよびＺｎなどを添加して硬
さや強度を増加して使用される。[Prior Art] Au is one of the few colored metals, along with Cu, and has been used as jewelry for a long time because of its beautiful golden color and ease of processing. However, since it is too soft as it is, it is generally used by adding Ag, Cu, Zn, etc. to increase its hardness and strength.
従来より装飾用Ａｕ合金のＡｕ量は、装飾用という使用
目的に鑑み、用途と色調に応じて、５０〜９２重量％の
筒中から決定されるのが一般的であり、これに対応して
、Ａｇが３〜３５重量％、Ｃｕが３〜４０重量％、Ｚｎ
が０．５〜１０重量％添加される。Conventionally, the amount of Au in decorative Au alloys has generally been determined from 50 to 92% by weight in the cylinder, depending on the purpose and color tone, considering the purpose of decorative use. Ag is 3-35% by weight, Cu is 3-40% by weight, Zn
is added in an amount of 0.5 to 10% by weight.
即ち、従来の装飾用Ａｕ合金は、Ａｇ３〜３５重量％、
Ｃｕ３〜４０重量％Ｚｎが０．５〜１０重量％を含むに
１２〜Ｋ２２が主流であった。That is, conventional decorative Au alloys contain 3 to 35% by weight of Ag;
The mainstream was 12 to K22 containing 3 to 40% by weight of Cu and 0.5 to 10% by weight of Zn.
［発明が解決しようとする問題点］
しかしながら、上述の構成の従来の合金系は、通常大気

Ｚｎは非常にガスを吸収し易いため、溶湯の流動性やイ
ンゴット内の鋳巣とそれに伴う加工性の低下、あるいは
鋳造体表面の肌荒れなどの欠陥を招来するという問題が
ある。[Problems to be solved by the invention] However, the conventional alloy system having the above-mentioned structure is usually melted and cast in the atmosphere, but the blended elements Ag, Cu, and Zn very easily absorb gas. However, there is a problem in that it causes defects such as fluidity of the molten metal, cavities in the ingot, resulting in a decrease in workability, and roughness on the surface of the cast body.
また、これらの合金系は、鋳造体そのものの硬さが低い
ため、例えば、指輪やネックレスにダイヤモンド、ルビ
ーなどの宝石を止める場合、宝石の止め爪の強度が弱い
ため爪の保持が弛み易く、宝石の脱落事故につながると
いう問題がある。In addition, these alloys have low hardness of the casting itself, so when securing a gemstone such as a diamond or ruby to a ring or necklace, for example, the strength of the retaining claw of the jewel is weak, so the holding of the claw tends to loosen. There is a problem in that it can lead to jewelry falling off.
さらに、ネクタイピン、ブローチ、眼鏡フレームなどの
細工に際しては、必ずロウ付工程を経ることになるが、
この際の加熱によって軟化が起り、当該箇所の強度が問
題になってくる。Furthermore, when crafting items such as tie pins, brooches, and eyeglass frames, a soldering process is always required.
The heating at this time causes softening, and the strength of the area becomes a problem.

金を提供することにある。In view of the above problems, the present invention eliminates the gas absorption effect during melting and casting of Ag, Cu, and Zn, and improves castability without impairing the aesthetic golden color of conventional decorative Au alloys. To provide a decorative Au alloy that can obtain a sound cast body, increase the hardness of the cast body, and exhibit excellent properties in terms of workability into plates and wires that require a brazing process. be.

Cast into a plate with a diameter of 5 mm and a length of approximately 10+w+ and heat it at 750℃.
After annealing, rolling was performed, and the processing and annealing were repeated at every 50% processing rate.

I observed the skin.

るいは硬さの増大が不充分なためである。In addition, in the present invention, the Ge content is 0.05 to 2% by weight.
The reason for limiting the amount is that adding more than 2% by weight will cause a significant drop in melting point and change in color, while adding less than 0.05% by weight will result in poor degassing effects, improved castability, or hardness. This is because the increase is insufficient.
一方、従添加元素としてのＦｅ、Ｃｒ、Ｃｏの添加量の

加ではＧｅとの相乗添加効果が期待できないためであり
、また、１重量％以上の添加は加工性を阻害したり、鋳
造性（流動性）にむしろ悪影響を及ぼすためである。On the other hand, the reason why the lower limit of the addition amount of Fe, Cr, and Co as secondary additive elements is limited to 0.01% by weight is that a synergistic addition effect with Ge cannot be expected if the addition is less than 0.01%. This is because addition of more than % by weight inhibits workability or has a rather negative effect on castability (fluidity).
上表から明らかなように、本実施例ｆ〜０はいずれも従
来例ａ〜ｅにくらべて、鋳造品の硬さも高く、加工性も
向上している。また、鋳造体の表面（ｆＡ肌）が美しく

く、非常に優れた鋳造性を示している。As is clear from the table above, all of Examples f to 0 have higher hardness and improved workability than Conventional Examples a to e. In addition, the surface of the cast body (fA skin) is beautiful, there are few internal defects (tA cavities), and the flowability to precision parts is good, indicating extremely excellent castability.
