Alclad 2524-T3 is a copper-aluminum-magnesium alloy with a pure aluminum corrosion-protective cladding, used primarily in aircraft fuselage and wing structures requiring high fatigue resistance and damage tolerance. The T3 temper (solution heat-treated and cold-worked) provides yield strength around 41 ksi with excellent fatigue performance and moderate corrosion resistance, suitable for high-cycle applications in the -55°C to 120°C temperature range.
