7475 aluminum is a zinc-copper-magnesium precipitation-hardened alloy engineered for high-strength aerospace structural applications, particularly where exfoliation corrosion resistance is critical; T651 temper (solution heat-treated, artificially aged, and stress-relieved by controlled stretching) provides ultimate tensile strengths in the 470–510 MPa range with improved through-thickness properties and corrosion resistance compared to T73 variants, making it suitable for highly loaded aircraft components including wing skins, fuselage frames, and pressure vessels.
