Title:
ALUMINUM ALLOY FIN MATERIAL FOR HEAT EXCHANGER AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2015/002314
Kind Code:
A1
Abstract:
Provided is an aluminum alloy fin material for a heat exchanger and characterized by containing 0.5-1.5 mass% of Si, over 1.0 mass% and no greater than 2.0 mass% of Fe, 0.4-1.0 mass% of Mn, and 0.4-1.0 mass% of Zn, the remainder comprising Al and unavoidable impurities, the pre-brazing-heating metal structure being such that the density of second phase particles having an equivalent circle diameter of less than 0.1 μm is less than 1×107
particles/mm2 and the density of second phase particles having an equivalent circle diameter of at least 0.1 μm is at least 1×105 particles/mm2, the pre-brazing-heating tensile strength (TSB) (N/mm2), post-brazing-heating tensile strength (TSA) (N/mm2), and fin material thickness (t) (μm) satisfying the relationship 0.4 ≤ (TSB - TSA)/t ≤ 2.1, and the thickness being no greater than 150 μm. Further provided is a method for producing same.
