ALUMINUM ALLOY MATERIAL FOR HEAT EXCHANGER FIN, MANUFACTURING METHOD FOR SAME, AND HEAT EXCHANGER USING THE ALUMINUM ALLOY MATERIAL
摘要:
Disclosed is an aluminum alloy material for a heat exchanger fin, the aluminum alloy material containing Si: 1.0% to 5.0% by mass, Fe: 0.1% to 2.0% by mass, and Mn: 0.1% to 2.0% by mass with balance being Al and inevitable impurities, wherein 250 pieces/mm2 or more to 7×104 pieces/mm2 or less of Si-based intermetallic compound particles having equivalent circle diameters of 0.5 to 5 μm are present in a cross-section of the aluminum alloy material; and wherein 10 pieces/mm2 or more and 1000 pieces/mm2 or less of the Al—Fe—Mn—Si-based intermetallic compounds having equivalent circle diameters of more than 5 μm are present in a cross-section of the aluminum alloy material. The aluminum alloy material may further contain one or more additive elements of Mg, Cu, Zn, In, Sn, Ti, V, Zr, Cr, Ni, Be, Sr, Bi, Na, and Ca.
