Abstract

PURPOSE:To provide a heat exchanger having excellent corrosion resistance and an excellent heat exchange characteristic by combining to braze and join brazing fins using of Al alloy of a specific composition as a core material and an Al-Si alloy as a skin material with an Al alloy tube having a potential nobler than that of the brazing fin. CONSTITUTION:The heat exchanger made of an aluminum alloy is made by combining to braze and join brazing fins using as a core material an Al alloy including 0.03-0.1% of Si, 0.05-0.3% of Fe, 0.01-0.3% of Zr, and 0.001-0.009% of In, the residual part being substantially Al, and using an Al-Si alloy as a skin material, with an Al alloy tube having a nobler potential. The components Si and Fe of the core material alloy have effects of improving the strength of the fin material Zr serves to improve the moldability of the fin material and the suspension resistance at high temperatures. In based on the corrosion potential of the fin material improves the victim anode effect.
