Disclosed is a high damage tolerant Al--Cu alloy of the AA2000 series
having a high toughness and an improved fatigue crack growth resistance,
including the following composition (in weight percent) Cu 3.8-4.7, Mg
1.0-1.6, Zr 0.06-0.18, Cr<0.15, Mn>0-0.50 , Fe.ltoreq.0.15,
Si.ltoreq.0.15, and Mn-containing dispersoids, the balance essentially
aluminum and incidental elements and impurities, wherein the
Mn-containing dispersoids are at least partially replaced by
Zr-containing dispersoids. There is also disclosed a method for producing
a rolled high damage tolerant Al--Cu alloy product having a high
toughness and an improved fatigue crack growth resistance, and
applications of that product as a structural member of an aircraft.
