Abstract
A method of forming a heat exchanger includes brazing heat exchanger components with a flux of non-corrosive fluoride complexes. The components comprise an aluminum alloy having improved brazing characteristics and containing 0.3 to 0.8% Mg, 4.0 to 8.0% Zn, one or more of 0.05 to 0.30% Zr, 0.05 to 0.30% Mn, 0.05 to 0.30% of Cr, 0.05 to 0.30% of Cu, aluminum and unavoidable impurities.
