【発明の詳細な説明】
本発明は、特に耐熱性と熱伝導性が優れた自動車のラジ
エーター、特にラジエーターフィン用銅合金に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile radiator having particularly excellent heat resistance and thermal conductivity, and particularly to a copper alloy for radiator fins.
自動車用ラジエーターは、エンジン部の温度を調節する
ために液体を冷却媒体としてエンジンとラジエーターと
を循環させて、熱を放散させるものであり、ラジエータ
ーフィンはチューブを通して熱を放散させる働きがある
。Automotive radiators circulate heat between the engine and the radiator using liquid as a cooling medium to adjust the temperature of the engine, and radiator fins work to dissipate heat through tubes.
そのため、従来ラジエーターフィン材料として熱伝導性
の高い銅合金が用いられている。しかるにラジエーター
フィンは、ラジエーター組立て時に種々の加熱処理が加
えられるため耐熱性が悪いとフィンの機械的強度を低下
せしめるこ、とになる。Therefore, a copper alloy with high thermal conductivity has been conventionally used as a radiator fin material. However, since radiator fins are subjected to various heat treatments when assembling the radiator, poor heat resistance will reduce the mechanical strength of the fins.

本発明ラジエーター用銅合金における合金成分について
の作用と添加量の限定理由について説明する。The effect of the alloy components in the copper alloy for radiators of the present invention and the reason for limiting the amount added will be explained.
Ｐｂを添加するのは、強度および耐食性を向上させるた
めであり、範囲を０．００１〜０．０５重量％に限定し
たのは０．００１重量％未満では、上記効果がほとんど

範囲を０．０５超〜０．１５重量％に限定したのは、０
．０５重量％以下では効果がほとんど期待できないため
であり、０．１５重量％を超えると熱伝導性が低下する
ためである。The purpose of adding Pb is to improve strength and corrosion resistance, and the reason why the range is limited to 0.001 to 0.05% by weight is because if it is less than 0.001% by weight, the above effects can hardly be expected. This is because if it exceeds .05% by weight, thermal conductivity and processability will decrease. The purpose of adding Ag and Sn is mainly to improve heat resistance.
The range was limited to more than 0.05 to 0.15% by weight.
．． This is because if the amount is less than 0.05% by weight, little effect can be expected, and if it exceeds 0.15% by weight, the thermal conductivity will decrease.
次に本発明合金の実施例を説明する。Next, examples of the alloy of the present invention will be described.

れかるように本発明合金は、耐熱性、熱伝導性の優れた
合金であることがわかる。Heat resistance was evaluated by heating three pieces of sample material at a predetermined temperature, and evaluating the softening temperature at the point where the strength was 80% of that before heating. In addition, thermal conductivity was evaluated by measuring electrical conductivity, which has a positive correlation with thermal conductivity. Note that the conductivity measurement was performed in accordance with JISH0505. The results are shown in Table 2. As can be seen from Table 2, the alloy of the present invention is an alloy with excellent heat resistance and thermal conductivity.
