The present invention relates to high corrosion-resistant aluminum alloy for a heat exchanger pipe and a heat exchanger pipe manufactured therefrom. The present invention has effects of having excellent corrosion resistance and strength, effectively suppressing reduction of elongation when a thin peelable pipe is manufactured, easily processing such as reduction of a pipe, expansion of a pipe, bending, etc., suppressing preferential corrosion of a processing part, and reducing manufacturing costs. 본 발명은 열교환기 배관용 고내식성 알루미늄 합금 및 이로부터 제조된 열교환기 배관에 관한 것이다. 구체적으로, 우수한 내식성 및 강도를 나타내고, 두께가 얇은 박리형 배관으로 제조시 신율의 저하를 효과적으로 억제함으로써, 결과적으로 배관의 확관, 축관, 굽힘 등의 가공이 용이하고 가공부의 우선적 부식을 억제할 수 있으며, 제조비용이 절감되는 알루미늄 합금 및 이로부터 제조된 열교환기 배관에 관한 것이다.
