COMBINATION PRESS ALUMINIUM ALLOY FIN MATERIAL FOR HEAT EXCHANGER, AND MANUFACTURING METHOD FOR SAME

WIPO Patent Application WO/2012/132785

A1

Aluminium alloy fin material, which is combination press fin material, is for a heat exchanger, and exhibits excellent collar-cracking resistance which can suppress the occurrence of collar cracking during a molding process, is formed from aluminium 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 combination press aluminium alloy fin material for a heat exchanger is characterised by having a thickness of less than 0.115mm, having a subgrain average particle diameter of 2.5μm or less and proof stress of 100-130N/mm2. The material is further characterised in that intermetallic compounds having a maximum length which exceeds 3μm are not more than 2000/mm2.
