本発明は耐汗性、ろう付性、及び切削性に優れた装身具
用白色合金に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a white alloy for jewelry having excellent sweat resistance, brazing properties, and cutting properties.
従来、めがねフレーム材及び腕時計の側やバンド材等肌
に直接音につけるものの材料にはに１４ホワイトゴール
ド、ロジウムメッキを施した洋白等が使用されている。Conventionally, 14 white gold, rhodium-plated nickel silver, and the like have been used for glasses frame materials, wristwatch sides, band materials, and other materials that come into direct contact with the skin.
然しなからに１４ホワイトゴールドはろう付性、切削性
には優れているが、使用していると徐々に光沢を失い、
白色から灰白色に変色し、またロジウムメッキを施した
洋白も同様にろう付性、切削性には優れているものであ
るが、使用しているとメッキがはがれたり、ピンホール
、クラックなどから洋白が汗により変色する等の欠点が
あり、いづれも耐汗性において満足できないものであっ
た。However, although 14 white gold has excellent brazing and cutting properties, it gradually loses its luster as it is used.
Nickel silver, which changes color from white to gray-white, and is rhodium-plated, has excellent brazing and cutting properties, but when used, the plating may peel off, pinholes, cracks, etc. Nickel silver has disadvantages such as discoloration due to sweat, and all of them are unsatisfactory in terms of sweat resistance.
これらのことから、ろう付性、切削性が良好であると同
時に特に耐汗性に優れ、装身具用として最適の白色合金
の出現が強＜要望されていた。For these reasons, there has been a strong demand for a white alloy that has good brazing properties and machinability, is particularly excellent in sweat resistance, and is ideal for use in jewelry.
そこで本発明者等は上記の要望に応えるため鋭意研究の
結果、従来のに１４ホワイトゴールドやロジウムメッキ
を施した洋白に劣らないろう付性、切削性を有すると同
時に特に優れた耐汗性を有するニッケルークロム−銅−
マンガン系の装身具用白色合金を見い出したものである
。In order to meet the above demands, the inventors of the present invention conducted extensive research and found that it has brazing and cutting properties comparable to conventional nickel silver plated with 14 white gold or rhodium plating, and at the same time has particularly excellent sweat resistance. nickel-chromium-copper-
We have discovered a white manganese-based alloy for jewelry.
本発明の装身具用白色合金は上記のニッケルークロム−
銅−マンガン系合金をベースとし、この合金に白金族元
素、金の中から選んだ二種以下の成分を添加した合金、
さらに上記合金に白金族元素、金の成分及び炭素を添加
した合金であって、これらの合金により装身具用として
最適の白色合金を提供して要望に応えんとするものであ
る。The white alloy for jewelry of the present invention is the above-mentioned nickel-chromium alloy.
An alloy based on a copper-manganese alloy, to which two or less elements selected from platinum group elements and gold are added.
Furthermore, the present invention is an alloy in which a platinum group element, a gold component, and carbon are added to the above-mentioned alloy, and these alloys are used to meet the demand by providing a white alloy that is most suitable for use in jewelry.
本発明の合金の一つはクロム５〜１５ ｗ／ ｏ未満、
銅１０〜２３ｗ１０１マンガン０．５〜１０ｗｗ１０及
び白金族元素、金の中から各々が０．０１〜３ ｗ ／
ｏの範囲内で二種以下と残部ニッケルよりなる特許請
求の範囲第１項に記載の合金である。One of the alloys of the invention has less than 5 to 15 w/o of chromium,
Copper 10-23w101 Manganese 0.5-10ww10 and platinum group elements, gold each at 0.01-3w/
The alloy according to claim 1, comprises two or less types within the range of o and the balance is nickel.
更に本発明の他の合金は特許請求の範囲第１項に記載の
合金に炭素０．０１〜０．２ ｗ ／ ｏを添加してな
る特許請求の範囲第２項に記載の合金である。Furthermore, another alloy of the present invention is the alloy described in claim 2, which is obtained by adding 0.01 to 0.2 w/o carbon to the alloy described in claim 1.
而して合金成分において、ニッケル中にクロムと銅とマ
ンガンを共添加することによって得られる最も大きな特
徴は耐汗性、ろう付性及び切削性が同時に改善されるこ
とである。Among the alloy components, the most significant feature obtained by co-adding chromium, copper, and manganese to nickel is that sweat resistance, brazing properties, and machinability are simultaneously improved.
単にニッケルとクロムのみの合金は、ろう付性、切削性
が悪く、ニッケルと銅のみの合金又ニッケルとマンガン
のみの合金は耐汗性が悪く、いずれも装身具用白色合金
としてはに１４ホワイトゴールドやロジウムメッキを施
した洋白に劣っている。Alloys containing only nickel and chromium have poor brazing and machinability, while alloys containing only nickel and copper or alloys containing only nickel and manganese have poor sweat resistance, and both are suitable for use as white alloys for jewelry. It is inferior to nickel silver with rhodium plating.
即ちニッケル中にクロムと銅とマンガンの共添加によっ
てはじめて装身具用白色合金として優れた効果を発揮し
得るものである。That is, it is only by co-adding chromium, copper, and manganese to nickel that it can exhibit excellent effects as a white alloy for jewelry.
更にこれらの合金に対し白金族元素、金の添加は何れも
耐汗性の改善に優れた効果を有し、また炭素を添加する
ことにより切削性が一層改善されたものとなる。Furthermore, addition of platinum group elements and gold to these alloys has an excellent effect on improving sweat resistance, and addition of carbon further improves machinability.
次に本発明合金の組成範囲について説明する。Next, the composition range of the alloy of the present invention will be explained.
特許請求の範囲第１項に記載の合金の組成分は、クロム
５〜１５ｗ１０未満、銅１０〜２３ｗ１０１マンガン０
．５〜Ｌｏｗ１０、及び白金族元素、金の中から各々が
０．０１〜３ｗ１０範囲内で二種以下と残部ニッケルで
ある。The composition of the alloy according to claim 1 is 5 to 15 w10 of chromium, 10 to 23 w10 of copper, 0 manganese.
．． 5 to Low10, and two or less of each of the platinum group elements and gold within the range of 0.01 to 3w10, and the balance is nickel.
ニッケルにクロムを添加することにより耐汗性に効果が
あることは知られているが、クロム５ ｗ ／ ｏ以下
では本発明の合金において耐汗の効果が弱く、クロム１
５ ｗ／ 。It is known that adding chromium to nickel has an effect on sweat resistance, but below 5 w/o of chromium, the sweat resistance effect is weak in the alloy of the present invention;
5 w/.
以上ではろう付性及び加工性を悪くするからクロム５〜
１５ｗ１０未満が適当である。Above that, the brazing properties and workability will deteriorate, so chromium 5~
Less than 15w10 is suitable.
また、この合金に銅を添加するとろうのぬれ性が良いこ
とからろう付性が改善されるが、銅１０ ｗ／ ｏ以下
ではろう付性があまり改善されず銅２３ ｗ ／ ｏ以
上では加工性が悪くなるから銅１０ｗ１０〜２３ｗ１０
が適当である。Additionally, adding copper to this alloy improves brazing properties due to its good wettability with the solder, but brazing properties do not improve much when copper is less than 10 w/o, and workability is poor when copper is more than 23 w/o. Copper 10w10 to 23w10 because it becomes bad.
is appropriate.
又マンガンは切削性を向上させる効果があることが知ら
れているが、マンガン０．５ｗ１０以下では切削性に寄
与する効果が小さくマンガン１０ｗ ／ ｏ以上では本
発明の合金の耐汗性を悪くするからマンガン０．５〜１
０ ｗ／ ｏが適当である。Furthermore, manganese is known to have the effect of improving machinability, but manganese below 0.5w/o has little effect contributing to machinability, and manganese above 10w/o deteriorates the sweat resistance of the alloy of the present invention. From manganese 0.5-1
0 w/o is appropriate.
次にニッケルークロム−銅−マンガン合金に更に白金族
元素、即ち、ルテニウム、ロジウム、パラジウム、オス
ミウム、イリジウム、白金及び金の中の二種以下を添加
すると白金族元素、金がいずれもニッケル、クロム、銅
よりも電気化学的に責な金属であるため、耐汗性が更に
改善される。Next, when two or less of platinum group elements, namely ruthenium, rhodium, palladium, osmium, iridium, platinum, and gold are further added to the nickel-chromium-copper-manganese alloy, both platinum group elements and gold become nickel. Since it is a metal that is more electrochemically sensitive than chromium or copper, its sweat resistance is further improved.
しかし、白金族元素及び金のいづれか一種が０．０１ｗ
１０以下だとニッケルークロム−銅−マンガン合金の耐
汗性を向上させることができず、３ ｗ ／ ｃ）以上
だと価格に対する耐汗性の向上比が減少しはじめるので
不適当である。However, one of the platinum group elements and gold is 0.01w
If it is less than 10, the sweat resistance of the nickel-chromium-copper-manganese alloy cannot be improved, and if it is more than 3 w/c), the ratio of improvement in sweat resistance to price begins to decrease, which is inappropriate.
又、白金族元素及び金の中から二種以下と限定したのは
、これら金属を三種以上いれても、価格の高い金や白金
族元素を使用するため、却って材料の管理やスクラップ
の際の回収作業等に手間と費用を増すだけだからである
。In addition, the reason why we limited the number of platinum group elements and gold to two or less is that even if three or more of these metals are included, the high price of gold and platinum group elements will be used, so it will be more difficult to manage materials and scrap. This is because it only adds to the effort and cost of collection work, etc.
従って白金族元素、金の中より二種以下で各々が０．０
１〜３ｗ１０の範囲内に限定して耐汗性を一層改善せし
めたものである。Therefore, less than two types of platinum group elements and gold are each 0.0
The sweat resistance is further improved by limiting the weight to within the range of 1 to 3w10.
又、更に特許請求の範囲第１項に記載の合金に炭素を添
加することによって、炭素が金属と金属炭化物を作り、
この金属炭化物が切削性を一層改善させるものである。Furthermore, by adding carbon to the alloy according to claim 1, carbon forms metal and metal carbide,
This metal carbide further improves machinability.
炭素０．０１ｗ１０以下では切削性を更に改善するだけ
の十分な金属炭化物が得られず、炭素０．２ｗ１０以上
では切削性はより向上するが、特許請求の範囲第１項に
記載の合金の耐汗性を極端に悪くするからである。If the carbon is less than 0.01w10, sufficient metal carbide cannot be obtained to further improve the machinability, and if the carbon is more than 0.2w10, the machinability is further improved, but the durability of the alloy according to claim 1 is This is because it makes sweating extremely bad.
従って、炭素の添加は０．０１〜０．２ ｗ ／ ｏの
範囲内に限定したものである。Therefore, the addition of carbon is limited to within the range of 0.01 to 0.2 w/o.
上述の如き成分と組成範囲を有する本発明は装身具用白
色合金として、耐汗性、切削性、ろう付性に何等支障な

するものである。The present invention, which has the above-mentioned components and composition range, can be used as a white alloy for jewelry without any problems in sweat resistance, machinability, and brazing properties, and can replace conventional 14 white gold or rhodium-plated nickel silver. It has excellent properties that allow it to
