本発明は、装飾用金合金の代用として用いられる黄金色
系銅合金に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a golden copper alloy used as a substitute for decorative gold alloys.
近年の省資源化に伴い、装飾用金合金の代用として黄金
色系合金材料が要求されている。With the recent efforts to save resources, golden alloy materials are required as a substitute for decorative gold alloys.
一般に装飾品に於いては、耐食性が良好であることが具
備条件の一つとされている。更には、これ等の装飾品は
装飾性の面から、複雑な加工が施される為、その加工が
容易であること、さらにその色が黄金色に近いことも併
せて要求されている。In general, one of the requirements for decorative items is good corrosion resistance. Furthermore, since these ornaments are subjected to complex processing for decorative purposes, they are also required to be easy to process and to have a color close to golden yellow.
ところで、装飾用黄金色系材料として用いられている合
金としてはＺ ｎ ３０ｗｔ％、残部Ｃｕより成る黄銅
合金があるが、この合金は耐食性が悪く、複雑な形状に
加工しづらいという欠点があった。Incidentally, an alloy used as a decorative golden-colored material is a brass alloy consisting of 30 wt% Zn and the balance Cu, but this alloy has the disadvantage of poor corrosion resistance and difficulty in processing into complex shapes. .
本発明は、上記の欠点を解消せんが為になされたもので
あり、銅系合金で耐食性、加工性（冷間加工性、切削性
）に優れ、かつ黄金色を有する装飾用黄金色系材料釡を
提供せんとするものである。The present invention has been made in order to eliminate the above-mentioned drawbacks, and is a decorative golden-colored material that is made of a copper-based alloy and has excellent corrosion resistance and workability (cold workability, machinability), and has a golden color. The purpose is to provide a pot.
本発明による装飾用黄金色系銅合金はＡ１２〜１０ｗｔ
％、ＰｂＯ０１〜３１１ｔ％、貴金属０．０１〜’ １
．８ｗｔ％、残部Ｃｕより成る合金である。The decorative golden copper alloy according to the present invention is A12~10wt.
%, PbO01~311t%, noble metal 0.01~' 1
．． It is an alloy consisting of 8 wt% and the balance Cu.
本発明による装飾用黄金色系銅合金に於いて、ＡＩを添
加した理由は、ＡＩはＣｕと合金を作った際に表面に安
定な酸化被膜を作り、耐食性を向上すると共に、黄金色
の合金が得られる為であり、２ｓｔ％未満ではその効果
が薄く、１０ｗｔ％を超えると金属間化合物を作り、薄
板に加工することが困難になる為である。The reason why AI is added to the decorative golden-colored copper alloy according to the present invention is that when alloyed with Cu, AI forms a stable oxide film on the surface, improving corrosion resistance and producing a golden-colored alloy. This is because if it is less than 2st%, the effect is weak, and if it exceeds 10wt%, intermetallic compounds are formed, making it difficult to process into a thin plate.
また、ｐｂを添加した理由はｐｂはＣｕ中にほとんど固
溶せず、はとんどが結晶粒界に粒状になって析出し、切
削性が良好になる為であり、０．１％未満ではその効果
が薄＜３ｗｔ％を超えると加工性が低下してくる為であ
る。In addition, the reason why Pb is added is that Pb hardly dissolves in solid solution in Cu, but mostly precipitates in the form of particles at grain boundaries, improving machinability, and is less than 0.1%. This is because when the effect exceeds 3wt%, the workability decreases.
また、貴会）属を添加した理由は、貴金属の微量添加に
よりＣｕ−Ａｌ合金の耐食性をさらに向上させる為であ
り、（１，０１ｗｔ％未満でばその効果が薄く、 １，
３ｗｔ％を超えてもあまり顕著な変化が見られなくなる
為である。ここで言う貴金属とは、Ａｕ。In addition, the reason for adding precious metals is to further improve the corrosion resistance of the Cu-Al alloy by adding a small amount of precious metals.
This is because even if the content exceeds 3 wt%, no significant change is observed. The precious metal referred to here is Au.
Ａｇ、Ｐｔ、Ｐｄ、Ｒｈ、Ｒｕ、Ｉ ｒ、Ｏｓを含めて
のことである。This includes Ag, Pt, Pd, Rh, Ru, Ir, and Os.
以下本発明による装飾用黄金色系銅合金の効果を明瞭な
