Abstract (en)

[origin: WO0198019A1] An aluminum filler alloy, particularly useful in fluxless controlled atmosphere brazing (CAB), contains from about 4 % to 20 % wt.% silicon (Si) and about 0.0008 % to 0.06 % sodium (Na). In addition to the sodium, the alloy may also contain bismuth (Bi) and/or potassium (K) in the ranges of about 0.0005 % to 0.03 % K, and from about 0.03 % to 0.133 % Bi. The filler metals can be clad to aluminum core alloys preferably from the 3XXX, 5XXX, or 6XXX alloys series.
