【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、ネクタイピン、
カフスボタン、時計枠、時計バンド、ライター、筆記用
具、眼鏡枠、イヤリング等の材料として使用する白金合
金の改良に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention is applicable to rings, necklaces, brooches, tie pins,
This invention relates to the improvement of platinum alloys used as materials for cufflinks, watch frames, watch bands, lighters, writing utensils, eyeglass frames, earrings, etc.
（従来技術とその問題点）
従来、上述の如き装飾品材料としては白金−パラジウム
（５〜１５重量％）合金が多用されている。然し乍ら白
金−パラジウム合金は加工性に優れているが、機械的強
さ特に硬さが低い為研摩中にすり傷、押傷が付き易く且
つ光沢が出にくく、また完成品として使用しているとき
も傷が付き易く、殊に宝石付指輪の場合には、宝石を止
めている部分がゆるんで宝石が脱落するという欠点があ
った。(Prior Art and its Problems) Conventionally, platinum-palladium (5 to 15% by weight) alloy has been widely used as a decorative material as described above. However, although platinum-palladium alloy has excellent workability, its mechanical strength and especially its hardness are low, so it is easily scratched and stamped during polishing, and it is difficult to produce gloss, and when used as a finished product. They are also easily scratched, and especially in the case of rings with jewels, the part that holds the jewels in place loosens and the jewels fall off.
また後者の白金−パラジウム−銅合金は、前記白金−パ
ラジウム合金と同様加工性に優れ、その上機械的性さに
も優れているが、鋳造時に鋳型と反応する為、細かい模
様が現われず、不鮮明になり、しかも鋳造時に巣が生じ
るという欠点があった。The latter platinum-palladium-copper alloy has excellent workability and mechanical properties as well as the platinum-palladium alloy, but because it reacts with the mold during casting, fine patterns do not appear. The problem was that it became unclear and that cavities were formed during casting.
（発明の目的）
本発明は上記欠点を解消せんが為になされたものであり
、加工性は勿論のこと機械的強さ、鋳造性に優れた装飾
用白金合金を提供んとするものである。(Object of the Invention) 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 platinum alloy for decoration that is excellent in not only workability but also mechanical strength and castability. .
（発明の構成）
本発明による装飾用白金合金は、白金８４〜９６重量％
、ニッケル１〜１０重量％、銅１〜１５重量％よりなる
成るものである。(Structure of the Invention) The decorative platinum alloy according to the present invention has a platinum content of 84 to 96% by weight.
, 1 to 10% by weight of nickel, and 1 to 15% by weight of copper.
本発明による装飾用白金合金に於いて、ニッケルを添加
した理由は、鋳造時に鋳型と反応しないこと及び鋳造時
に酸素濃度を抑制できることの条件を満し、機械的強さ
及び鋳造性を向上させる為であり、その添加量を１〜１
０重量％とじたのは１重量％未満では機械的強さ及び鋳
造性の向上が低く、１０重量％を超えると加工性が著し
く低下するからである。The reason for adding nickel to the decorative platinum alloy according to the present invention is to satisfy the conditions of not reacting with the mold during casting, suppressing oxygen concentration during casting, and improving mechanical strength and castability. and the amount added is 1 to 1
The reason why it is set at 0% by weight is because if it is less than 1% by weight, the improvement in mechanical strength and castability will be low, and if it exceeds 10% by weight, the workability will be significantly reduced.
また銅は白金と金属間化合物を作り、硬化して一層機械
的強さを向上させる為であり、その添加量が１重量％未
満では機械的強さの改善が殆んどなく、１５重量％を超
えると加工性が悪くなるからである。In addition, copper forms an intermetallic compound with platinum and hardens to further improve mechanical strength. If the amount added is less than 1% by weight, there is almost no improvement in mechanical strength, and 15% by weight This is because if it exceeds this, workability will deteriorate.
以下本発明による装飾品用白金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 platinum alloy for ornaments according to the present invention.
（実施例及び従来例）
下表の左欄に示す成分塑性の実施例１〜３の装飾品用白
金合金と従来例１．２の装飾品用白金合金の硬さ、鋳型
の細かい模様の再現度及び巣の発生度合いについて夫々
測定したところ・、下表の右欄に示すような結果を得た
。(Example and Conventional Example) Hardness of the platinum alloys for ornaments of Examples 1 to 3 of the component plasticity shown in the left column of the table below and platinum alloys for ornaments of Conventional Examples 1.2, and reproduction of the fine pattern of the mold. When we measured the frequency and the degree of nest occurrence, we obtained the results shown in the right column of the table below.
上記表で明らかなように本発明による装飾品用白金合金
は、従来の装飾品用白金合金に比し焼なまし後の硬さが
優れ、鋳造した際の鋳型の細かい模様の再現度合も極め
て優れていることが判る。As is clear from the table above, the platinum alloy for decorative items according to the present invention has superior hardness after annealing compared to conventional platinum alloys for decorative items, and the reproduction of fine patterns in the mold when cast is also extremely high. It turns out to be excellent.
（発明の効果）
以上詳記した通り本発明の装飾品用白金合金は、加工性
、機械的強さ、鋳造性が極めて優れているので、従来の
装飾品用白金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。(Effects of the Invention) As detailed above, the platinum alloy for ornaments of the present invention has extremely excellent workability, mechanical strength, and castability, so it can be used as a substitute for conventional platinum alloys for ornaments. It can be said that it is temporary.
