Title:
ALUMINUM ALLOY BRAZING SHEET FOR FIN, HEAT EXCHANGER, AND METHOD FOR PRODUCING HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2014/065355
Kind Code:
A1
Abstract:
Provided is an aluminum alloy brazing sheet for a fin in which one side only of a core formed from an aluminum alloy is clad with a brazing material formed from an aluminum alloy comprising Si and Zn. The aluminum alloy brazing sheet for a fin is characterized in that the thickness of the aluminum alloy brazing sheet for a fin is 0.15 mm or less, and in three-minute heating tests at 600ºC, the potential difference between the surface on the core side and the surface on the brazing material side of the brazing sheet after the heating test is -40 to +40 mV. The present invention enables the provision of an aluminum alloy brazing sheet for a fin of a heat exchanger that is an aluminum alloy brazing sheet for a fin in which one side only of a core is clad with a brazing material and corrosion resistance of the fin material is improved and corrosion resistance with respect to the tube material is excellent.
