Document Type and Number:
WIPO Patent Application WO/2019/181768
Kind Code:
A1
Abstract:
This aluminum alloy fin material for a heat exchanger is characterized by comprising an aluminum alloy containing 1.00-1.60 mass% of Mn, 0.70-1.20 mass% of Si, 0.05-0.50 mass% of Fe, 0.05-0.35 mass% of Cu, and 1.00-1.80 mass% of Zn, the remaining portion being Al and incidental impurities, wherein the matrix of the aluminum alloy has a fibrous structure, and the aluminum alloy fin material has a tensile strength of 170-230 MPa. The present invention can provide an aluminum alloy fin material that is for a heat exchanger and that has superior moldability before brazing, superior brazeability, and superior strength characteristics and corrosion resistance after brazing.
