Abstract
Brazing sheet for flux-free brazing, wherein an outermost surface brazing filler metal layer, consisting of an Al—Si-based alloy containing 4 to 12% Si in mass %, and an intermediate brazing filler metal layer, consisting of an Al—Si—Mg-based alloy containing 1% or more and less than 4% Si and 0.1 to 5.0% Mg in mass %, are cladded on one side or both sides of a core material, and wherein aluminum members are joined to each other without using flux in a non-oxidizing gas atmosphere under normal pressure with an oxygen concentration of 300 ppm or less, using the brazing sheets.
