Abstract
An aluminum brazing sheet for use in brazing comprises; PA0 a core material composed of an aluminum alloy containing: PA1 0.2-1.0 wt % Cu, PA1 0.2-0.8 wt % Mg and PA0 at least one of the elements selected from: PA1 0.05-0.5 wt % Mn, PA1 0.05-0.5 wt % Zr, PA1 0.05-0.5 wt % Cr, and PA1 the balance of Al and impurities, and PA0 a filler material composed of an Al-Si based alloy brazing material coated on one surface of said core material and a skin material composed of a sacrificial aluminum anode material at a purity higher than 99.0 wt % coated on the other surface of the core material. The aluminum brazing sheet according to this invention is satisfactory in the brazing property and also excellent in the corrosion resistance and the strength, which is suitable as the material for use in aluminum heat exchangers.
