摘要： A sheet material (1) includes a stiffness-increasing concave-convex part (20). A first reference plane (K1), an intermediate reference plane (K3), and a second reference plane (K2) serve as a reference system. The intermediate reference plane is partitioned by first lattice straight lines (L1), second lattice straight lines (L2), and third lattice straight lines (L3) so as to define hexagonal unit areas (24) and triangular unit areas (25) in the intermediate reference plane. Areas that include a plurality of the hexagonal unit areas and the triangular unit areas are designated as first, second and third reference areas (214, 224, 234), respectively. Combinations thereof constitute new first, second and third reference areas (213, 223, 233), respectively. The concave-convex part includes first areas (21) and second areas (22), which respectively include the new first reference areas and the new second reference areas, and third areas (23), which include the new third reference areas.

摘要： An aqueous aluminum brazing composition containing an organic binder and a zinc-based flux which prevents the precipitation of the zinc-based flux having a large specific gravity while securing an excellent brazeability. The thixotropic index of the brazing composition is adjusted to 1.01-1.20 by adding a (meth)acrylic acid/(meth)acrylate copolymer emulsion to the brazing composition as a precipitation inhibitor in an amount of 0.03-1.50 wt % of 100 wt % of the brazing composition. Since the (meth)acrylic acid/(meth)acrylate copolymer emulsion is used as the precipitation inhibitor in a specific amount instead of other types of compounds used for a powder-containing paint, such as ultrafine particle silica, poly(meth)acrylate, or polyvinyl alcohol, the precipitation of the zinc-based flux can be prevented without impairing the brazeability.
