Aluminum fin material and filler metal for heat exchanger, and aluminum heat exchanger comprising same

The present invention relates to an aluminum fin material and a filler metal for a heat exchanger, and to an aluminum heat exchanger comprising the fin material and the filler metal. The present invention relates to the fin material and the filler metal, which have an optimum anti-corrosion design and are used together with an aluminum alloy tube of Korean Patent registration No. KR 10-1465389 of the present research group, thereby enabling the lifespan of the heat exchanger to improve. Particularly, the compositions of the fin material and the filler metal are controlled, thereby being optimized so as to be capable of acting as a sacrificial anode for the aluminum tube.
