<P>PROBLEM TO BE SOLVED: To solve the problem that, when brazing is performed, the kind and using method of a brazing filler metal are restricted by shape, clearance, the use-nonuse of flux, a brazing system or the like, and working efficiency is inferior; and further, to solve the problem that, when brazing heating is performed by using flux, a step is also needed of removing the residue of the flux remaining in a part with complicated shape, and that productivity is deteriorated. <P>SOLUTION: Brazing is performed without using flux by using an aluminum alloy brazing filler metal wire obtained by disposing the outside of an aluminum alloy brazing filler metal containing, by mass, 5 to 13% Si and 0.1 to 5% Mg, and the balance Al with inevitable impurities with a skin material composed of an aluminum material having a solidus temperature higher than the liquidus temperature of the brazing filler metal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
