【発明の詳細な説明】
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ナサしたもので
、あり、銅系合金で耐食性、加工性に優れ、かつ黄金色
を有する装飾用黄金色系鋼合金を提供せんとするもので
ある。The present invention was made in order to eliminate the above-mentioned drawbacks, and it is an object of the present invention to provide a decorative golden-colored steel alloy that is a copper-based alloy, has excellent corrosion resistance and workability, and has a golden color. be.
本発明による装飾用黄金色系銅合金はＺｎ７〜４５−ｔ
％、貴金属０゜０１〜５ｗｔ％、残部Ｃｕより成る合金
である。The decorative golden copper alloy according to the present invention is Zn7-45-t.
%, noble metal 0°01 to 5 wt%, and the balance is Cu.
本発明による装飾用黄金色系銅合金に於いて、Ｚｎを添
加した理由は、ＺｎはＣｕと合金を作った際に黄金色が
得られる為であり、７ｗｔ％未満ではその効果が薄く、
４５ｗｔ％を超えるとβ相が現われ、薄板に加工するこ
とが困難になる為である。The reason why Zn is added to the decorative golden copper alloy according to the present invention is that Zn produces a golden color when alloyed with Cu, and if it is less than 7 wt%, the effect is weak.
This is because if it exceeds 45 wt%, β phase will appear, making it difficult to process into a thin plate.
また、貴金属を添加した理由は、貴金属の微量添加によ
りＣｕ−Ｚｎ合金の耐食性を大いに向上させる為であり
、０．０１ｗｔ％未満ではその効果が薄く、５ｗｔ％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。In addition, the reason for adding precious metals is to greatly improve the corrosion resistance of the Cu-Zn alloy by adding a small amount of precious metals.If the amount is less than 0.01wt%, the effect is weak, and if it exceeds 5wt%, there is no noticeable change. This is because it will not be seen.
ここで言う貴金属とは、Ａｕ。The precious metal referred to here is Au.
Ａｇ、ＰＬ、Ｐｄ、’ Ｒｈ、Ｒｕ、Ｉｒ、Ｏｓを含め
てのことである。This includes Ag, PL, 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
らしめる為に実施例及び従来例について述べる。Examples and conventional examples will be described below in order to clarify the effects of the decorative golden copper alloy according to the present invention.
第１表に示す成分組成の実施例１〜４の装飾用黄金色系

上記で明らかなように本発明による装飾用黄金色系銅合
金は従来の装飾用黄金色系銅合金に比し、耐汗性、加工
性が優れ、かつ黄金色を有していることが判る。As is clear from the above, the decorative golden-colored copper alloy according to the present invention has superior sweat resistance and processability, and has a golden color, compared to conventional decorative golden-colored copper alloys. .
以上詳記した通り、本発明の装飾用黄金色系銅合金は、
耐汗性、加工性が優れかつ黄金色を有しているので、従
来の装飾用黄金色系銅合金にとって代わることのできる
画期的なものと言える。As detailed above, the decorative golden copper alloy of the present invention is
Because it has excellent sweat resistance, workability, and a golden color, it can be said to be an epoch-making product that can replace conventional decorative golden copper alloys.
