Abstract (en)

[origin: EP2692881A1] Aluminum alloy fin material, which is drawless-press fin material, is for a heat exchanger, and exhibits excellent collar-cracking resistance which can suppress the occurrence of collar cracking during a forming process, is formed from aluminum alloy material which contains 0.010 - 0.4 mass% of Fe, the remainder of which is formed from Al and unavoidable impurities, and in which the Al purity is at least 99.30 mass%. The drawless-press aluminum alloy fin material for a heat exchanger is characterized by having a thickness of less than 0.115 mm, having a subgrain average particle diameter of 2.5 µm or less and proof stress of at least 130 N/mm 2 . The material is further characterized in that intermetallic compounds having a maximum length which exceeds 3 µm are not more than 2,000/mm 2 .
