PURPOSE:To improve brazability mechanical strength and further, workability as fitting members of a heat exchanger by making iron-based material to core material and covering Al-based material having satisfactory brazing property on one surface thereof at least. CONSTITUTION:The structure of a bracket 6 for fitting of a fitting part is that of three layers. Namely, the iron-based material is provided as the core material 10 on the center and a brazing side covering layer 11 and a corrosion protective surface side covering layer 12 of Al-based material are covered on both sides or the front and rear surfaces thereof. When such joined structure is made, the bracket 6 for fitting is provided with mechanical strength and satisfactory workability by the core material 10 of the iron-based material and also provided with satisfactory brazing property by the brazing side covering layer 11. Thus, in the structure where the heat exchanger such as a capacitor 1 specially is fitted to a prescribed part, the fitting member structure with mechanical strength, workability and brazing property is provided. |
