Abstract
【課題】プラチナはその希少性の故に高価である。また、プラチナ（比重２１．４）は比重が大きいため、ネックレス等の宝飾用の鎖に使用した場合、全体の重量が大きくなり、トップの大きさを制限する必要が出て来る。
【解決手段】パラジウムを９５．０質量％、プラチナを１．０質量％、ルテニウムを４．０質量％含むことを特徴とするパラジウム合金を作成し、軽量化と低価格化を実現し、ネックレス、指輪、ピアス、眼鏡フレームなどの宝飾装身具用素材として使用する。
【選択図】なしPlatinum is expensive because of its rarity. Also, platinum (specific gravity 21.4) has a large specific gravity, so when used for jewelry chains such as necklaces, the overall weight increases and the top size must be limited.
A palladium alloy characterized by containing 95.0% by mass of palladium, 1.0% by mass of platinum, and 4.0% by mass of ruthenium is realized, and the weight is reduced and the price is reduced. Used as a material for jewelry such as rings, earrings, and eyeglass frames.

Description
本発明は、宝飾装身具に用いるパラジウム合金に関し、プラチナの様な深みのある光沢を備え、耐蝕性及び耐変色性に優れ、プラチナよりも廉価なパラジウム合金に関する。 The present invention relates to a palladium alloy used for jewelry accessories, and relates to a palladium alloy having a gloss as deep as platinum, excellent in corrosion resistance and discoloration resistance, and cheaper than platinum.
従来の宝飾装身具に用いる白色系合金はプラチナの含有量が多いプラチナ合金が中心となっている。本発明は、白色系宝飾装身具用の合金として、変色しにくく、宝飾としての輝きにも優れ、プラチナよりも廉価に製造できるパラジウムを９５．０質量％としている。 White alloys used in conventional jewelry are mainly platinum alloys with a high platinum content. The present invention is 95.0% by mass of palladium which is difficult to discolor as an alloy for white jewelry, is excellent in shine as a jewelry, and can be manufactured at a lower cost than platinum.
プラチナはその希少性の故に高価である。また、プラチナ（比重２１．４）は本発明（比重１２．０）よりも比重が大きいため、ネックレス等の宝飾用の鎖に使用した場合、全体の重量が大きくなり、トップの大きさを制限する必要が出て来る。Platinum is expensive because of its rarity. Platinum (specific gravity 21.4) has a higher specific gravity than the present invention (specific gravity 12.0), so when used for jewelry chains such as necklaces, the overall weight increases and the size of the top is limited. The need to come out.
パラジウムを９５．０質量％、プラチナを１．０質量％、ルテニウムを４．０質量％含むことを特徴とする宝飾装身具用パラジウム合金。A palladium alloy for jewelry, comprising 95.0% by mass of palladium, 1.0% by mass of platinum, and 4.0% by mass of ruthenium.
本発明の宝飾装身具用パラジウム合金は、プラチナと同等の輝きを持ち、変色しにくいのでメッキがいらず、硬い（ビッカーズ硬度１４０〜１６０）だけでなく粘りがあるので加工性にも優れ、本発明により白色系宝飾装身具用素材を廉価に提供できる。また、プラチナ（比重２１．４）よりも本発明（比重１２．０）は軽いので、本発明を鎖に使用した場合は、トップをより大きくすることができる。The palladium alloy for jewelry according to the present invention has the same brightness as platinum and is not easily discolored, so it does not require plating, and is not only hard (Vickers hardness 140 to 160), but also has a high viscosity and excellent workability. This makes it possible to provide materials for white jewelry accessories at a low price. Moreover, since this invention (specific gravity 12.0) is lighter than platinum (specific gravity 21.4), when this invention is used for a chain | strand, a top can be enlarged more.
パラジウムを９５．０質量％、プラチナを１．０質量％、ルテニウムを４．０質量％含むパラジウム合金を作成し、軽量化と低価格化を実現し、ネックレス、指輪、ピアス、眼鏡フレームなどの宝飾装身具用素材として使用する。A palladium alloy containing 95.0% by mass of palladium, 1.0% by mass of platinum, and 4.0% by mass of ruthenium is created to reduce weight and price, such as necklaces, rings, earrings, and eyeglass frames. Used as a material for jewelry.
