【発明の詳細な説明】
（産業上の利用分野）
本発明は耐食性及び機械的強度の優れた銀合金材料に関
するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver alloy material with excellent corrosion resistance and mechanical strength.
（従来技術とその問題点）
一般に時計ハント、時計枠、ライター等装飾関係に用い
られる金属材料は耐食性１機械的強度の優れたものが、
要求されている。従来これらの目的の為にはＡ ｇ ９
５− Ｃｕ ５ 、 Ａ ｇ ９２．５− Ｃｕ ７
．５゜Ａｇ９Ｏ−ＣｕｌＯが用いられることが多かった
が、耐食性が劣ること、色調的にも銀に比べやや黄味が
かって見劣りしており、且つ硬さが装飾用としては低い
為、傷つき易い等の欠点があった。(Prior art and its problems) In general, metal materials used for decorative purposes such as watch handles, watch frames, lighters, etc. have excellent corrosion resistance and mechanical strength.
requested. Conventionally, for these purposes A g 9
5-Cu5, Ag92.5-Cu7
．． 5゜Ag9O-CulO was often used, but it has poor corrosion resistance, has a slightly yellowish color tone compared to silver, and is less hard than silver, so it is easily scratched. There was a drawback.
（発明の目的及び構成）
本発明はこれらの欠点を解消すべくなされたもので、本
発明の耐食性合金は、ｐｔ、Ａｕが単独か複合で５〜１
５重量％とＺｎ、３ｎ、ｉｎの少なくとも一種以上が５
〜１０重量％と残部Ａｇからなるものである。(Object and structure of the invention) The present invention has been made to eliminate these drawbacks, and the corrosion-resistant alloy of the present invention has a content of 5 to 1% of PT and Au, either alone or in combination.
5% by weight and at least one of Zn, 3n, and in.
~10% by weight and the balance is Ag.
かかる本発明の耐食性銀合金においてＰＬ、Ａｕが単独
又は複合で５〜１５重量％とじたのは５重量％未満では
耐食性の向上が期待出来ず、又１５重量％を超えると耐
食性は向上するものの価格的に高価なものとなり、実用
に供しない為である。In the corrosion-resistant silver alloy of the present invention, if PL and Au are contained in an amount of 5 to 15% by weight alone or in combination, if it is less than 5% by weight, no improvement in corrosion resistance can be expected, and if it exceeds 15% by weight, although corrosion resistance will be improved. This is because it is expensive and cannot be put to practical use.
Ｚｎ、 Ｓｎ、Ｉｎを単独又は複合で５〜１０重量％
添加する目的は耐食性とＡｇの色調をそこなわない範囲
で、機械的強度、硬さを増し、耐摩耗性を向上し、傷を
つきにくくするためで、５重量％未満ではその効果が十
分現われず、１０重量％を超えると加工性が悪くなるも
のである。Zn, Sn, In alone or in combination 5 to 10% by weight
The purpose of adding it is to increase mechanical strength and hardness, improve wear resistance, and make it less likely to be scratched without damaging the corrosion resistance and color tone of Ag. If it is less than 5% by weight, the effect will not be fully realized. First, if it exceeds 10% by weight, processability will deteriorate.
（実施例及び従来例）
本発明による耐食性銀合金と従来の銀合金についてその
特性を下記の表に示す。(Examples and Conventional Examples) The characteristics of the corrosion-resistant silver alloy according to the present invention and the conventional silver alloy are shown in the table below.
（以下余白）
ここで機械的性質は３０％冷間圧延加工時の特性を示す
ものであり、また耐食性は鏡面研摩したサンプルを人工
汗中、５％食塩中への浸漬２４時間後の表面の変色状態
を示すものである。(Left below) Mechanical properties indicate the properties during 30% cold rolling, and corrosion resistance indicates the surface properties after 24 hours of immersing a mirror-polished sample in artificial sweat and 5% common salt. This indicates a discolored state.
Ｘ印は変色発生、○印は変色なく頭初の表面状態を維持
した場合を示す。The X mark indicates that discoloration occurred, and the O mark indicates that the initial surface condition of the head was maintained without discoloration.
上記の表から本発明の銀合金が腕時計ケース等の装飾用
として十分なる機械的強度と耐食性を具備した合金であ

られない貴金属調の高級な外観を呈するものであった。Next, the alloys of Example No. 3 were melted and cast by high-frequency induction heating, cold-rolled to create a plate material with a thickness of 3.5 mm, which was then press punched and then cold stamped. A blank was prepared, and after annealing at 550° C. 2 +1r, finishing stamping was performed. Next, by polishing this to create a watch case with a mirror-finished surface, a white case with excellent gloss was obtained. In the commonly conducted corrosion resistance tests (i.e., immersion tests, etc.), this case showed properties comparable to those of cases made of stainless steel, nickel silver, or brass with 20% gold alloy plating. It had a precious metal-like, high-class appearance that is difficult to obtain.
