本発明は、ネクタイピンのばね、クリップ状のブローチ
等の装飾品用白金合金ばね材の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for manufacturing a platinum alloy spring material for decorative items such as tie pin springs and clip-shaped brooches.
（従来の技術）
従来より装飾品用白金合金としては、Ｐｔ−Ｐｄ二元系

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場合も傷が付き易く、また宝石付
指輪の場合、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。However, although the Pt-Pd binary alloy has excellent workability and castability, it has low mechanical strength, especially hardness, so it is easily scratched and pressed during polishing, and it is difficult to produce gloss. Furthermore, when used as a finished product, it is easily scratched, and in the case of rings with jewels, the part that holds the jewels loosens, causing the jewels to fall off.

為、鋳巣が生じるという欠点があった。In addition, Pt-Pd-Cu ternary alloy has excellent workability and mechanical strength like the Pt-Pd binary alloy, but it reacts with the mold during casting, so it has fine patterns. The problem was that the porosity did not appear and became unclear, and furthermore, the oxygen concentration could not be suppressed, resulting in the formation of cavities.
このような欠点を解消するものとして、加工性は勿論の

ところで、上記の白金８４〜９６重１％、ガリウム１〜

には使用できなかった。(Refer to Japanese Unexamined Patent Publication No. 59-150042) (Problem to be solved by the invention) By the way, the above-mentioned platinum 84-96% by weight, gallium 1-1%
Platinum alloys for decorations, which are made of 10% by weight and the balance copper, are heated during brazing of parts during the manufacturing process of decorations, so that the material that has been hardened by processing becomes soft. Therefore, it could not be used for, for example, clip-type ornaments that utilize spring properties.
そこで本発明は、上記白金、ガリウム、銅より成る装飾
品用白金合金に於いて、硬く、ばね性に優れ、クリップ
タイプの装飾品として好適なばね材の製造方法を提供し
ようとするものである。Therefore, the present invention aims to provide a method for manufacturing a spring material that is hard, has excellent spring properties, and is suitable for clip-type ornaments in the platinum alloy for ornaments made of platinum, gallium, and copper. .

ある。(Means for Solving the Problems) In order to solve the above problems, the method for producing a platinum alloy spring material for decorative articles of the present invention includes platinum of 84 to 96% by weight and 1% by weight of umum.
In the method for manufacturing a platinum alloy spring material for decorative items consisting of ~10% by weight and 0.5~10% by weight of copper, after brazing the parts,
It is characterized by heat treatment at 400 to 600°C.
本発明の装飾品用白金合金ばね材の製造方法に於いて、

るとばね材が軟らかくなったり、ろう材が溶けたりする
からである。In the method for manufacturing a platinum alloy spring material for decorative articles of the present invention,
The reason for heat treatment at 400 to 600℃ after parts brazing is to harden the spring material by dispersing and precipitating gallium in the crystals. Below 400℃, the spring material will not harden sufficiently, and if the temperature exceeds 600℃, the spring material will harden. This is because it may become soft or the brazing material may melt.

In the platinum alloy spring material for decorative items that has been softened by brazing the parts, Ga is dispersed and precipitated in the crystals, increasing the hardness and increasing the springiness, which enhances the function of clip-type decorative items, that is, the clamp holding function. A platinum alloy spring material having the following properties is obtained.

As is clear from the table above, according to the example of the method for manufacturing platinum alloy spring materials for decorative articles of the present invention, the hardness after brazing the parts was reduced by annealing. However, it can be seen that the hardness significantly increased due to heat treatment. This is simply because Ga in the spring material was dispersed and precipitated in the crystals due to the heat treatment. In this way, the platinum alloy spring material for ornaments has strong spring properties and has a clamp holding function for clip-type ornaments.
