【発明の詳細な説明】
本発明は、特に熱伝導性、耐食性および鞠性に優れた自
動車のラジエーター、特にラジエーターフィン用鋼合金
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile radiator, particularly a steel alloy for radiator fins, which has excellent thermal conductivity, corrosion resistance, and ballability.
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、自動車の走行中に
ラジエーターは排気ガス、塩分を含む海岸大気さらには
工場大気のＳ０２ガス等にさらされている場合、フィン
は腐食してラジエーターの放熱性、強度を著しく損う恐
れがある。Therefore, copper alloys with high thermal conductivity have conventionally been used as radiator materials. However, if the radiator is exposed to exhaust gas, coastal air containing salt, or S02 gas from factory air while the car is running, the fins may corrode, significantly reducing the heat dissipation performance and strength of the radiator. .

鋼合金を開発した。As a result of research conducted in view of this, the present invention has been developed based on Pbo.
001~1. and one or more selected from the group consisting of Si, AI, and P in a total amount of 0.001% by weight.
We have developed a steel alloy for radiators with excellent thermal conductivity and corrosion resistance, consisting of ~0.15% by weight, the balance being copper and its accompanying impurities.

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 radiator of the present invention, particularly in the steel alloy for radiator fins, and the reason for limiting the amount added will be explained.

．１５重量％に限定したのは、０．００１重量％未満で

量％を越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 range is 0.001 to 1. The reason why the content is limited to 1% by weight is that if it is less than 0.001% by weight, the above effects can hardly be expected, and if it exceeds 1.0% by weight, thermal conductivity and processability will decrease. The purpose of adding Si, P, and P is to control the amount of oxygen in molten steel and improve corrosion resistance as a deoxidizing agent during melting, and the range is 0.001 to 0.
．． The reason why the amount is limited to 15% by weight is because if it is less than 0.001% by weight, almost no effect can be expected, and if it exceeds 0.15% by weight, the thermal conductivity decreases.
次に本発明合金の実施例について説明する。Next, examples of the alloy of the present invention will be described.
