<P>PROBLEM TO BE SOLVED: To provide a structure, which is formed using an aluminum-alloy material and little changed in form and size after jointing, and in which to-be-jointed members are jointed without using a jointing member such as a brazing filler metal or a filler metal, and to provide a jointing method for the same structure. <P>SOLUTION: A structure is formed by using an aluminum-alloy material as one of to-be-jointed materials, and using any of an aluminum-alloy material, a pure aluminum material, and a metal material other than aluminum as the other of to-be-jointed materials, and by jointing the one and other of to-be-jointed materials without using a jointing member. The aluminum-alloy material as one of to-be-jointed materials contains 1.5-5.0% Si, 0.3-2.0% Mg, and the balance Al with inevitable impurities. The structure after jointing is almost identical in form and size with itself before jointing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
