PURPOSE:To obtain an Al alloy brazing sheet for non-corrosive brazing by incorporating a specific ratio of Be into at least either of an Al-Si brazing filler metal and Al alloy core material which is specified in the content of Mg so that the thinner material can be formed. CONSTITUTION:The Al alloy brazing sheet for non-corrosive brazing consists of the Al-Si brazing filler metal and the Al alloy core material which contains 0.2-1.5wt.% Mg and the balance Al. This brazing sheet is increased in the permissible content of Mg in the material by incorporating 0.001-0.05wt.% Be into at least either of the brazing filler metal and the core material. The high-strength Al alloy brazing sheet for non-corrosive brazing which permits formation of the thinner material is thereby obtd. |
