An extrudable aluminum alloy composition includes, in weight percent, between 0.60 and 0.90 manganese, between 0.45 and 0.75 copper, between 0.05 and 0.24 magnesium, less than 0.30 iron, less than 0.30 silicon , less than 0.05 titanium, less than 0.05 vanadium, and a Cu/ ratio higher or equal to 3. It also relates to aluminum alloy heat exchanger extruded or dra wn tube and extruded or drawn aluminum alloy tubing having the above-described aluminum alloy composition. It also relates to a heat exchanger comprising a plurality of extruded or drawn tube sections having the above-described aluminum alloy composition and a process for manufacturing same.
