Clad 7475 aluminum is a high-strength 7xxx-series alloy (Zn-Mg-Cu system) with a thin pure aluminum cladding layer for enhanced corrosion resistance, used primarily in aerospace structural applications requiring exceptional strength-to-weight ratios and fatigue performance. The T761 temper (overaged condition) provides reduced quench sensitivity and improved stress-corrosion cracking resistance compared to peak-aged conditions, with yield strengths approximately 440–480 MPa and ultimate tensile strengths of 500–550 MPa in sheet form.
