Brazeable aluminum alloy cast material and method of brazing the same |
摘要 |
Objects of the present invention are to provide a brazeable aluminum alloy cast material which can be manufactured brazeable products without lowering the productivity and the method of brazing a cast material. The cast material is composed of: 0.5-4.5% by weight of Mn; 0.5-3% by weight of Si; 0.5-1% by weight of Fe; and the balance composed of aluminum and impurities. In the method of brazing the cast material, a brazing agent and/or flux are used, the brazing agent is composed of: 25-65% by weight of Zn; 2-7% by weight of Si; and the balance composed of aluminum and 0.1% or less of Fe as one of impurities. The flux is a mixture of: 0.5-5% by weight of LiF; 1-10% by weight of ZnCl2; 1-5% by weight of K alpha AlF alpha +3 ( alpha is an integer not less than 1.); and the balance composed of BaCl2-KCl-NaCl.
