<P>PROBLEM TO BE SOLVED: To provide a method for producing a brazing product of a soft aluminum and a different material, in which the brazing product which is hardly cracked by relieving the stress of a joining interface in a thermal cycle is produced by a simple step. <P>SOLUTION: An aluminum base material (10) includes an aluminum alloy containing 0.1 to 0.5 mass% Mg and 0.1 mass% or less in total of impurities, and the balance consisting of Al. A material (15) for brazing is produced by allowing Si particles (11) having an average particle size of 25 μm or less to collide against the outside of at least one surface of the aluminum base material (10) by a cold spray to form a Si layer (12) in which the amount of Si adhesion is 3 to 10 g/m<SP POS="POST">2</SP>. The material (15) for brazing and the different material (16) are attached by performing vacuum brazing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
