。Generally, for items that require white color like this,
Brass was plated and used, but there was a problem that the plating would peel off, so there was a desire to develop a copper alloy material that was white in color and was inexpensive.
上記の代表的な例として鍵について説明すると。Let's explain the key as a typical example of the above.
自動車用あるいは住宅用鍵には、黄銅３種にＮｌないし
Ｃｒをメッキしたものが使用されており。Three types of brass plated with Nl or Cr are used for automobile and residential keys.

（１）白色美麗であること
（２）強度が高いこと
（３）耐食性に優れていること
（４）被剛性に優れていること

次に本発明合金を構成する合金成分及び内容の限定理由
について説明する。Next, the reasons for limiting the alloy components and contents constituting the alloy of the present invention will be explained.
Ｃｕ及びＺｎは本発明合金の基本成分であり。Cu and Zn are the basic components of the alloy of the present invention.
加工性２機械的性質に優れている。Ｚｎ含有量を２０〜
４０ｗｔ％とする理由は、Ｚｎ含有量が２０ｗｔ％未満
では強度が十分ではなく、Ｚｎ含有量が４０ｗし％を超
えると、加工性が劣化する為である。Workability 2: Excellent mechanical properties. Zn content 20~
The reason for setting it to 40 wt% is that if the Zn content is less than 20 wt%, the strength will not be sufficient, and if the Zn content exceeds 40 wt%, the workability will deteriorate.
Ｎｉ含有量を２〜１０ｗｔ％とする理由は。What is the reason for setting the Ni content to 2 to 10 wt%?
Ｎｉ含有量が２ｗｔ％未満では白色を呈せず、また強度
、及び耐食性が十分ではなく、Ｎｉ含有量が１０ｗｔ％
を超えると加工性が悪くなり、また価格も高くなるため
である。Ｍｎを添加するのは。If the Ni content is less than 2 wt%, it will not exhibit white color, and the strength and corrosion resistance will not be sufficient, and if the Ni content is less than 10 wt%.
This is because if it exceeds this, workability will deteriorate and the price will also increase. What is the reason for adding Mn?
Ｎｉよりも安価で、かつ銅合金を白色化できるため一部
Ｎｉの代替材として使用でき、しかも熱間加工性を向上
させるからである。Ｍｎ含有量を１〜１０ｗｔ％とする
理由は、Ｍｎ含有量が１ｗｔ％未満では白色化及び熱間
加工性及び強度の向上の効果が認められず、またＭｎ含
有量が１０ｗｔ％を超えると逆に加工性が劣化するため
である。This is because it is cheaper than Ni and can whiten copper alloys, so it can be used as a partial substitute for Ni, and it also improves hot workability. The reason why the Mn content is set to 1 to 10 wt% is that when the Mn content is less than 1 wt%, the effect of whitening and improving hot workability and strength is not observed, and when the Mn content exceeds 10 wt%, the effect of improving hot workability and strength is not observed. This is because processability deteriorates.
Ｓｎを添加するのは９強度及び耐食性を向上させるため
であり、Ｓｎ含有量を０．０１〜３ｗｔ％とする理由は
、Ｓｎ含有量がＯ，０１ｗｔ％未満では強度及び耐食性
の向上が認められず、Ｓｎ含有量が３ｗｔ％を超えると
加工性が劣化し、また価格も高くなるためである。The purpose of adding Sn is to improve strength and corrosion resistance, and the reason why the Sn content is set to 0.01 to 3 wt% is that when the Sn content is less than 0.01 wt%, improvements in strength and corrosion resistance are observed. First, if the Sn content exceeds 3 wt%, processability will deteriorate and the price will also increase.
また、Ｐｂは被削性を向」ニさせるために添加するが、
Ｐｂ含有量を０．０１〜４．０ｗｔ％とする理由は、Ｐ
ｂ含有量がＯ，０１ｗｔ％未満では被削性の向上が認め
られず、また４、０ｗｔ％を超えると、加工性が劣化す
るからである。In addition, Pb is added to improve machinability, but
The reason for setting the Pb content to 0.01 to 4.0 wt% is that Pb
This is because if the b content is less than 0.01 wt%, no improvement in machinability is observed, and if it exceeds 4.0 wt%, the workability deteriorates.
さらに副成分としてＴｅ、Ｃｒ、Ｇｏ、Ｚｒ。Furthermore, Te, Cr, Go, and Zr are sub-components.
Ｖ ｒ Ｂ ｅ ＨＣｄ ＨＡ ｓ ｒ Ｐを添加する

The reason why it is set as 0.01 wt% is that if the content is less than 0.01 wt%, these improvement effects will not be recognized, and if it exceeds 3 wt%, the workability and machinability will deteriorate.
