Abstract: A high corrosion resistance heat exchanger is disclosed, which has improved corrosion resistance. The improved corrosion resistance is achieved by controlling alloy components in a tube material and a fin material and inducing sacrificial corrosion of the fin material. The high corrosion resistance heat exchanger includes a tube having a channel formed therein to allow a refrigerant to flow, and a plurality of fins coupled to the outer circumferential surface of the tube. The fins may contain 0.1 wt % to 0.45 wt % of Mg, and 0.5 wt % to 0.8 wt % of Zn, a remainder wt % of Al.
