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
を説明する。ＣｕとＺｎは本発明合金の基本合金成分で
あり、所定量において加工性１機械的強度に優れている

〜４５ｗｔ％とする理由は、Ｚｎ含有光が１０ｗｔ％未
満では加工性が悪くなり、Ｚｎ含有量が４５ｗｔ％を越
えると十分な機械的強度が得られないからである。Ｐの
含有量を０．００５〜０．１０ｗｔ％とする理由は。Next, the reasons for limiting the alloy components and contents constituting the alloy of the present invention will be explained. Cu and Zn are the basic alloy components of the alloy of the present invention, and in a predetermined amount, they have excellent workability and mechanical strength as well as good thermal conductivity. Zn content 10
The reason for setting it to 45 wt% is that if the Zn content is less than 10 wt%, processability will be poor, and if the Zn content exceeds 45 wt%, sufficient mechanical strength will not be obtained. What is the reason for setting the P content to 0.005 to 0.10 wt%?
Ｐの含有量が０．００５ｗｔ％未満では耐食性の改善が
みられず、逆にＰの含有量が０．１０ｗｔ％を越えると
耐食性は改善されるが１粒界腐食の徴候が見られるため
である。Ｓｎの含有量が０．０５ｗｔ％未満では耐食性

効果が飽和するためである。Ａ１の含有量を０．０５〜
１．０ｗｔ％とする理由は、Ａｌの含有量が０．０５ｗ
ｔ％未満では耐食性の改善が認められず、また１、０ｗ
ｔ％を越えるとその効果が飽和するためである。If the P content is less than 0.005 wt%, no improvement in corrosion resistance is observed, and conversely, if the P content exceeds 0.10 wt%, corrosion resistance is improved, but signs of intergranular corrosion are seen. be. This is because if the Sn content is less than 0.05 wt%, no improvement in corrosion resistance is observed, and if it exceeds 1.0 wt%, the effect is saturated. A1 content from 0.05 to
The reason for setting it to 1.0wt% is that the Al content is 0.05w.
At less than t%, no improvement in corrosion resistance is observed, and at 1,0 w
This is because the effect becomes saturated if it exceeds t%.
またｇ Ｍ ｎ及びＳｉを添加することにより黄銅中に
Ｍ ｎ −Ｓ ｉ系の金属間化合物を析出させ、耐摩耗
性を向上させる。Ｍｎ含有量を０．１〜６．０ｗｔ％と
するのは、Ｍｎ含有量が０．１ｗｔ％未満ではＳｉを３
．０ｗｔ％添加しても、十分な耐摩耗性が得られず、逆
にＭｎ含有量が６．Ｏｗ ｔ％を越えると加工性が劣化
するためである。Ｓｉ含有量を０．０５〜３．０ｗｔ％
とするのは、Ｓｉ含有量が０．０５ ｗ ｔ％未満では
、Ｍｎを６．０ｗｔ％添加しても十分な耐摩耗性が得ら
れず、逆にＳｉ含有量が３．０ｗｔ％を越えると加工性
が劣化するためである。Furthermore, by adding g M n and Si, an M n -S i type intermetallic compound is precipitated in the brass, thereby improving wear resistance. Setting the Mn content to 0.1 to 6.0 wt% is because when the Mn content is less than 0.1 wt%, Si is
．． Even if 0 wt% is added, sufficient wear resistance cannot be obtained, and conversely, when the Mn content is 6. This is because if it exceeds Ow t%, workability deteriorates. Si content 0.05-3.0wt%
This is because if the Si content is less than 0.05 wt%, sufficient wear resistance cannot be obtained even if 6.0 wt% of Mn is added, and conversely, if the Si content exceeds 3.0 wt% This is because the processability deteriorates.
さらにｐｂは被耐性を向上させる。ｐｂ含有量を０．１
〜４．Ｏｗ ｔ％とする理由は、ｐｂ含右、辰が０．１
ｗｔ％未満では被削性の向上が認められず、４．０ｗｔ
％を越えると加工性が劣化するからである。Furthermore, pb improves tolerance. PB content 0.1
~4. The reason for Ow t% is that PB is included and the dragon is 0.1.
No improvement in machinability was observed at less than 4.0 wt%.

2. aims to improve the mechanical strength and wear resistance of the alloy of the present invention without impeding its corrosion resistance, but if its content is less than 0.005 wt%, the effect of its addition will be weak, and conversely, 2. This is because if it exceeds 0 wt%, the effect is saturated and workability deteriorates.
