An aluminum core alloy for use in the manufacture of brazed heat exchanger assemblies having high resistance to corrosion and moderate strength. A preferred composition of the aluminum base alloy consists of from 0.13 to 0.22% titanium, from 0.8 to 1.5% manganese, 0.4 to 0.6% copper, up to 0.7% iron, up to 0.3% silicon, up to 0.3% magnesium, with the balance being essentially aluminum and normal impurities. Another preferred composition, which is a modification of the preceding composition, includes 0.3 to 0.6% magnesium.

Aluminum alloys suitable for use as anode structures in electrochemical cs are disclosed. These alloys include iron levels higher than previously felt possible, due to the presence of controlled amounts of manganese, with possible additions of magnesium and controlled amounts of gallium.
