<p><P>PROBLEM TO BE SOLVED: To provide a Zn-Al-Cu alloy rolled material which can be used as an intermediate material for obtaining a zinc alloy foil for brazing free from generation of cracks in the material when being rolled even if fatigue strength after brazing and joining is enhanced by adding Cu to zinc together with Al as an alloy element, or a zinc alloy foil for brazing as it is, and to provide a method for producing the same. <P>SOLUTION: The Zn-Al-Cu alloy rolled material includes 3.5-18 mass% Al, 1-3.5 mass% Cu, and the rest Zn and inevitable impurities. In the alloy rolled material, there exist four or more elemental Cu particles with the average crystal grain size of 10-40μm per 500μm<SP POS="POST">2</SP>. The thickness of the alloy rolled material is 80-150μm. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
