PROBLEM TO BE SOLVED: To provide soldering slurry which can carry out soldering at a low temperature and is inexpensive, and further to provide an aluminum alloy sandwich panel which has been soldered using the same soldering slurry, and is light-weighted, has an excellent appearance, and is inexpensive. SOLUTION: Mixed slurry for soldering an aluminum alloy contains a soldering material composed of a powder aluminum alloy having an average grain diameter of 10 to 100μm, which powder aluminum alloy has been manufactured by spraying and quenching the molten metal of the aluminum alloy containing 23 to 37 mass% of Cu and 4 to 10 mass% of Si in a vacuum or an inert gas, and a fluoride flux including 11 mass% or more of CsF as a solid component. The aluminum alloy sandwich panel is formed by soldering face plate materials 2 and core materials 3 using the mixed slurry for soldering. COPYRIGHT: (C)2006,JPO&NCIPI
