What Is 7475 Aluminum?

7475 is a high-strength 7xxx alloy engineered specifically for superior toughness and fracture resistance, even in thicker sections. Commonly supplied in T761 temper for aircraft fuselage and wing skins, it is the preferred choice for critical structures where both strength and durability matter. Linsy supplies 7475 sheet, plate, bar and tube with full MTC documentation. Its high zinc content gives an outstanding strength-to-toughness combination, making it a staple for aircraft skins and bulkheads.

Proprietà meccaniche in base al trattamento termico

Typical T761 values (converted from source KSI): tensile ≈ 524 MPa (76 ksi), yield ≈ 441 MPa (64 ksi), elongation ≈ 12%, shear ≈ 317 MPa (46 ksi). Confirm against the MTC for your form and thickness.

Temperamento Temperamento Tensile (MPa) Yield (MPa) Elong. (%)
T761 ≈ 524 ≈ 441 ≈ 12
T7351 ≈ 510 ≈ 425 ≈ 12

Guida alla scelta della tempra

T761 — peak combination of strength and toughness for skins and structural plate. T7351 — improved stress-corrosion resistance. Both are overaged; not weld-friendly.

Caratteristiche principali

Superior Toughness
