ABSTRACT:
A typical aluminum alloy brazing material includesover 7.0 wt. % and not more than 12.0 wt. % of Si: over 0.1 wt. % and not more than 8.0 wt. % of Cu. over 0.05 wt. % and not more than 0.5 wt. % or Fe, further at least one kind selected from a group consisting of over 0.5 wt. % and not more than 5.5 wt. % of Zn. over 0.002 wt. % and not more than 0.3 wt % of In and over 0.002 wt. % and not more than 0.3 wt. % of Sn, and the balance of Al an inevitable impurities. A typical cladded aluminum alloy brazing sheet with a three-layer structure includes a brazing material, a core material comprising over 0.6 wt. % and not more than 2.5 wt. % of Si, over 0.5 wt. % and not more 2.5 wt. % of Cu, over 0.05 wt. % and not more than 2.0 wt. % of Mn, and the balance of Al and inevitable impurities, and a sacrificial material comprising at least one kind selected from a group consisting of over 0.5 wt. % and not more than 6.0 wt. % of Zn. over 0.002 wt. % and not more than 0.3 wt. % of In, and over 0.002 wt. % and not more than 0.3 wt. % of Sn, and the balance of Al and inevitable impurities, or comprises a core material cladded both sides thereof with the brazing material. By using the inventive brazing materials or brazing sheets, the brazing heating can be performed at a temperature of 570.degree. to 585.degree. C.
