Title: BRAZING SHEET AND PRODUCTION METHOD THEREFOR
Abstract:
Provided are: a brazing sheet that exhibits an excellent brazeability in brazing within an inert gas atmosphere and is able to curb an increase in material cost; and a production method therefor. This brazing sheet has: a core material having a chemical composition comprising 0.20-1.3 mass% of Mg with the remainder being Al and unavoidable impurities; and a brazing material that has a chemical composition comprising 6.0-13.0 mass% of Si, 0.0040-0.070 mass% of Bi, and not less than 0.050 but less than 0.10 mass% of Mg, the remainder being Al and unavoidable impurities, and that is laminated over the core material. This brazing sheet is applicable to brazing that is performed in an inert gas atmosphere or in vacuum without using flux.
