ALUMINUM ALLOY BRAZING SHEET, INSTALLATION BODY OF ALUMINUM ALLOY FOR BRAZING, AND METHOD FOR BRAZING ALUMINUM ALLOY MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an aluminum alloy brazing sheet capable of obtaining favorable joint condition, an installation body of aluminum alloy for brazing, and a method for brazing an aluminum alloy material.;SOLUTION: A brazing sheet is obtained by cladding an aluminum alloy brazing material on one or both surfaces of an aluminum alloy core material so that the aluminum alloy brazing material positions on an outermost surface, bringing an aluminum or aluminum alloy member to be brazed into contact with the brazing material to join in a non-oxidation atmosphere accompanying no pressure reduction. The aluminum alloy brazing material has a composition comprising, by mass, 3 to 13% Si, 0.1 to 3.0% Mg, 0.0001 to 3.0% Ce, one or both of 0.001 to 1.0 Sr and 0.0001 to 0.1% Be as desired, and the balance Al with inevitable impurities.;COPYRIGHT: (C)2015,JPO&INPIT
