PROBLEM TO BE SOLVED: To provide a method of joining aluminum material capable of joining aluminum material to each other, or joining the aluminum material with an aluminum-ceramic composite at temperature of more than 350°C and less than 600°C.SOLUTION: Zn-Al-based alloy brazing metal with Al concentration of 0.5 to 13 mass%, or Zn-Cu-based alloy filler metal with Cu concentration of 0.5 to 8 mass% is used as brazing metal. CsF-AlF-based eutectic flux is used as a flux. The brazing metal with the flux being added thereto is melted and cooled under atmospheric pressure to form a brazing-joined layer 3 of thickness of 0.02 to 0.2 mm. Thus, each aluminum material 1 is joined to each other or the aluminum material 1 and an aluminum-ceramic composite 2 are joined to each other. |
