An aluminum alloy brazing sheet having high strength comprising: a core alloy; an Al-Si-based filler alloy cladded on one side or both sides of the core alloy, wherein the core alloy is composed of an aluminum alloy containing 0.3-1.2% (mass%, the same applies the below) Si, 0.05-0.4% Fe, 0.3-1.2% Cu, 0.3-1.8% Mn, 0.05-0.6% Mg, and containing one or more elements selected from the group consisting of 0.02-0.3% Ti, 0.02-0.3% Zr, 0.02-0.3% Cr and 0.02-0.3% V, the balance of A1 and unavoidable impurities; and wherein, after the aluminum alloy brazing sheet is subjected to brazing, the core alloy features a metallic structure in which a density of intermetallic compounds having a grain diameter of at least 0.1 µm is at most ten grains per µm 2 .
摘要:
A resin-coated aluminum alloy sheet material for an aluminum electrolytic capacitor case has a superior formability even when being formed into an aluminum electrolytic capacitor case having a large height/diameter ratio, using a volatile press oil. A resin layer contains wax composed of at least one of polyethylene wax and carnauba wax, and has a thickness falling within a range from at least 2 µm to at most 22 µm. A total of lengths of wax particles, defined when the wax particles are cut along a straight line of 100 µm optionally drawn on the surface of the resin layer, is at least 10 µm. A number of the wax particles, featured by a cross-sectional shape having a size of at most 80 % of the thickness of the resin layer and of at least 0.1 µm, is from at least 3 to at most 50. A number of the wax particles, featured by a cross-sectional shape featured by a major axis extent having a size of more than 80 % of the thickness of the resin layer is less than 10. Although the resin-coated aluminum alloy sheet material is formed into an aluminum electrolytic capacitor case having a large height/diameter ratio, cracks and peelings do not occur in the resin layer.
