2025 aluminum alloy (Cu-Mg primary alloying elements) is a heat-treatable aerospace alloy used in aircraft structural components requiring high strength-to-weight ratio; T6 temper (solution heat-treated and artificially aged) provides yield strengths in the 50-57 ksi range with moderate elongation, suitable for die-forged critical aircraft parts operating at room temperature with good fatigue resistance.
