Yes. Every material ultimately has a fatigue limit; there's nothing you can stress indefinitely without it eventually breaking. Now, other materials can move the number of possible cycles up and down, and potentially move the number up sufficiently that it becomes a non-concern (because other factors would drive airlines to sell and scrap the old aircraft), but it'll never be infinite.

That's not entirely true, see: https://en.wikipedia.org/wiki/Fatigue_limit

"Ferrous alloys and titanium alloys have a distinct limit, an amplitude below which there appears to be no number of cycles that will cause failure."
