PROBLEM TO BE SOLVED: To easily and securely join an aluminum material and an iron material. SOLUTION: AlaZnbCucMgd (where (a), (b), (c) and (d) are in mass%, while (a) is the balance, 5≤b≤12, 0≤c≤2, 0.5≤d≤3, and inevitable impurities can be included) which is an alloy solutionizable to the aluminum material and the iron material or the alloy material having a composition shown by 0.5 in the lower limit of the described above (c) is held between both the materials and is joined thereto. The alloy material to be held therebetween is foil or powder and the thickness of the foil is≤150μm and the central grain size of the powder is≤150μm. The alloy material to be held therebetween in joining is joined by holding the material at the temperature below its liquid phase temperature and pressurizing the material. COPYRIGHT: (C)2003,JPO |
