Clad 7475-T7351 is a high-strength aluminum alloy (7xxx series, zinc-primary) with a thin corrosion-resistant aluminum or aluminum-alloy cladding layer, solution heat-treated, stress-relieved by controlled stretching, and artificially aged to T7351 condition for maximum stress-corrosion cracking (SCC) resistance while maintaining high yield strength (typically 415–435 MPa). This temper is specified for critical aerospace structures, particularly fuselage skins and other damage-tolerant applications where both strength and SCC resistance in marine or humid environments are required.
