7175 is a high-strength 7xxx alloy designed for superior toughness — often favored over 7075 where fracture resistance matters more than peak strength. Linsy supplies 7175 plate, bar and tube in T74, T7452 and T7454 tempers with full MTC documentation for aerospace and high-stress applications.
Available forms: plate / sheet / bar / tube
Common tempers: T74 / T7452 / T7454
Processing support: CNC machining, forging support, anodizing
Quality documents: MTC report with every order
7175 is a high-strength 7xxx alloy designed for superior toughness — often favored over 7075 where fracture resistance matters more than peak strength. Linsy supplies 7175 plate, bar and tube in T74, T7452 and T7454 tempers with full MTC documentation for aerospace and high-stress applications. Its improved toughness helps it perform under stress and impact, making it a common choice for forged and machined aircraft parts.

T74 / T7452 / T7454 — overaged tempers that maximize toughness and stress-corrosion resistance; T7452 is for die forgings, T7454 for hand forgings. Choose based on form and toughness needs.
Better fracture resistance than 7075 at slightly lower strength.
Machines well in overaged tempers.
Not recommended for fusion welding.
Aircraft structural forgings, gears and shafts, high-stress machine parts, automotive and aerospace components.
CNC machining supported; anodizing available. Overaged tempers machine more predictably than T6.
Every order ships with an MTC. SGS third-party test reports available on request. Linsy holds ISO 9001, ISO 14001 and ISO 45001.
