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.
