PROBLEM TO BE SOLVED: To realize appropriate brazing using an Al-Si-Mg base brazing material during brazing.SOLUTION: A method of brazing aluminum materials with each other by using a cladding material obtained by bonding an Al-Si-Mg brazing material containing, by mass%, 0.2-3.0% of Mg and 3-12% of Si to an aluminum alloy core material, in which an organic resin consisting only of C, H, and O is interposed at least in a bonded portion between the Al-Si-Mg based brazing material and the aluminum bonded member before brazing, and a surface of the bonded portion is protected from the atmosphere with a carbide film obtained by the organic resin as a barrier during brazing heating.SELECTED DRAWING: Figure 1 |
