Brazed aluminum composite having improved resistance to intergranular corrosion. The core alloy consists essentially of from 1 to 1.5% manganese, from 0.1 to 0.4% chromium, from 0.1 to 0.4% copper, from 0.01 to 0.6% silicon, from 0.01 to 0.7% iron, balance essentially aluminum. The cladding brazing alloy consists essentially of from 4 to 14% silicon, from 0.05 to 0.2% bismuth and the balance essentially aluminum. The brazed alloy composite provides galvanic protection against intergranular corrosion.
