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.

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.

T761 — peak combination of strength and toughness for skins and structural plate. T7351 — improved stress-corrosion resistance. Both are overaged; not weld-friendly.
Among the toughest 7xxx grades for thick sections.
Suited to cyclic-load aircraft skins.
Not recommended for fusion welding.
Aircraft fuselage and wing skins, high-toughness structural parts, bulkheads, critical military components, aerospace fasteners.
CNC machining and saw cutting supported; anodizing with sealant advised for corrosion service.
Every order ships with an MTC. SGS third-party test reports available on request. Linsy holds ISO 9001, ISO 14001 and ISO 45001.
