The present invention relates to an optimal copper alloy for use in marine Q-interfaces such as water intake grates.
黄銅系合金は一般に機械的性質や成形性が良好であり、
その他の銅合金に比べ価格も安いため、広範囲の用途で
使用されており、復水器管などの熱交換器用材料として
多く使用されている。Brass-based alloys generally have good mechanical properties and formability,
Because it is cheaper than other copper alloys, it is used in a wide range of applications, and is often used as a material for heat exchangers such as condenser tubes.
ところで復水器管は淡水又は海水等の引込口近くの内面
、曲り部等で局部的に流速が大きくなったり、乱流を生
ずる場所で著しい腐食を受けろいｂゆるエロージョンコ
ロ−ジョンが発生し問題になっている。By the way, condenser pipes are susceptible to severe corrosion at locations where the flow velocity locally increases or turbulence occurs, such as on the inner surface near the inlet of freshwater or seawater, or at bends. It's becoming a problem.
これらの復水器用材料としては、従来アルミニウム黄銅

ルミニウム黄銅も海水中へ微量のＦｅイオンを供給する
防食法を併用しているという現状である。Conventional materials for these condensers include aluminum brass (Cu-Zn-Sn alloy) and aluminum brass (Cu-Zn-Sn alloy).
Zn-Al-As alloy) is mainly used, but it does not have sufficient 20-John corrosion resistance, and aluminum brass is used almost exclusively for freshwater applications. The current situation is that anti-corrosion methods that supply Fe ions are also used.
又、一部の復水器管には、キュブロニッケル（Ｃｕ−Ｎ
ｉ合金）も使用されているが、価格が高いという欠点が
ある。In addition, some condenser tubes are made of cubronickel (Cu-N
i alloy) is also used, but it has the disadvantage of being expensive.
この様な状況から、耐エロージョンコロ−ジョン性に優

次に本発明の各成分の限定理由について具体的に説明す
る。Next, the reason for limiting each component of the present invention will be specifically explained.
Ｃｕ及びＺｎは本発明合金の基本成分であり、加工性１
機械的性質、及び熱伝導性を良好に保有せしめるｅＺｎ
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なく、Ｚｎ含有量が４
０ｗｔ％を超えると加工性が劣化する為である。Cu and Zn are the basic components of the alloy of the present invention, and the workability 1
eZn has good mechanical properties and thermal conductivity
The reason why the content is set to 20 to 40 wt% is that if the Zn content is less than 20 wt%, the strength is insufficient;
This is because if it exceeds 0 wt%, workability deteriorates.
Ｎｉ含有量を２〜１０ｗｔ％とする理由は、Ｎｉ含有量
が２ｗｔ％未満では強度及び耐食性が十分でなく、Ｎｉ
含有量が１０ｗｔ％を超えると加工性が悪くなり、又価
格も高くなるためである。The reason why the Ni content is set to 2 to 10 wt% is that if the Ni content is less than 2 wt%, the strength and corrosion resistance are insufficient, and the Ni
This is because if the content exceeds 10 wt%, processability will deteriorate and the price will also increase.
Ｍｎを添加するのは、Ｎｉよりも安価でかつ強度及び耐
食性を向上させるため一部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０Ｍｎ含有
量を１〜１０ｗｔ％とする理由は、Ｍｎ含有量が１ｗｔ
％未満では強度、耐食性及び熱間加工性の向上の効果が
認められず、又Ｍｎ含有量が１０ ｗ ｔ％を超えると
逆に加工性が悪化するためである。The reason for adding Mn is that it is cheaper than Ni, improves strength and corrosion resistance, can be used as a partial substitute for Ni, and also improves hot workability. The reason for this is that the Mn content is 1wt.
This is because if the Mn content is less than 10 wt%, no effect of improving strength, corrosion resistance, and hot workability will be observed, and if the Mn content exceeds 10 wt%, workability will deteriorate.
Ｓｎを添加するのは、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
加工性が悪化し、又価格も高くなるためである。The reason why Sn is added 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%, the strength and corrosion resistance are improved. First, if the Sn content exceeds 3 wt%, processability will deteriorate and the price will also increase.
さらに副成分としてＴｅ、Ｃｒ、Ｇｏ、Ｚｒ。Furthermore, Te, Cr, Go, and Zr are added as subcomponents.
Ｖ、Ｂｅ、Ｃｄ、Ａｓ、Ｐを添加するのは１強度及び耐
食性を向上させるからである。The reason for adding V, Be, Cd, As, and P is to improve strength and corrosion resistance.
これら副成分の内１種若しくは２種以上を０゜０１〜３
ｗｔ％とする理由は、Ｏ，０１ｗｔ％未満では添加によ
る強度及び耐食性の向上の効果が認められず、又３ｗｔ
％を超えると加工性が劣化するからである。One or more of these sub-ingredients at 0°01-3
The reason why it is set as 0.01 wt% is that if the addition of O is less than 1 wt%, the effect of improving strength and corrosion resistance will not be recognized, and if O.
%, workability deteriorates.
