ABSTRACT:
A vacuum-brazing aluminum cladding material consisting of a core member and a first and a second clad which cover at least one surface of the core member. The first clad consists of 6-14% by weight of Si, 0-0.6% by weight of Mg and the balance being at least Al, and the second clad formed on the first clad consists of 0-14% by weight of Si, 0.8-2.5% by weight of Mg and the balancing being at least Al. The second clad has a thickness of at least 5"m, and this thickness and a content of Si determined so as to satisfy a formula t.ltoreq..vertline.100/(10-c).vertline., wherein, "t" is the thickness (.mu.m) of said second alloy clad, and "c" is the content (% by weight) os Si of the second clad.
