AL ALLOY BRAZING SHEET FOR HEAT EXCHANGER STRUCTURAL MEMBER

摘要

PURPOSE: To prepare an Al alloy brazing sheet for heat exchanger structural member, capable of holding high strength even after brazing treatment. ;CONSTITUTION: This Al alloy brazing sheet can be produced by cladding at least one side of a core material of Al alloy, which has a composition consisting of, by weight, 0.7-1.5% Si, 1.5-3% Mn, 0.01-0.25% V, 0.01-O.25% Zr, 0.01-0.25% Cr, and the balance Al with inevitable impurities and further containing, if necessary, one or ≥2 kinds among 0.2-1.5% Fe, 0.02-0.25% Ti, 0.05-0.3% Mg, and 0.05-1% Cu, with a brazing filler metal of Al-Si alloy.;COPYRIGHT: (C)1995,JPO
