What is 7095?
7095 is a spray-formed Al-Zn-Mg-Cu alloy of the 7000-series family (UNS A97095), stocked in O and F plus the T6/T651 peak-aged and T73, T7351, T74, T7451, T76, T7651 and T77 over-aged tempers. Engineers specify it as thick plate where static strength governs, with default values of 675 MPa yield, 710 MPa tensile, 10% elongation and 190 HB, as used on 787-class wing skins and fuselage panels. The trade-offs are typical 7000-series ones: no fusion welding, a low corrosion rating (35/100), a 120 °C service ceiling and limited mill availability, so 7055 or 7150 plate is the usual substitute. 7095 has a density of 2.86 g/cm³ (0.103 lb/in³), heavier than 97% of aluminum grades. It melts at 470°C (878 °F). 7095 has a yield strength of 675 MPa (97.9 ksi) and a tensile strength of 710 MPa (103 ksi) — stronger than 100% of aluminum grades. Elongation at break is 10% and the elastic modulus is 71.5 GPa (10.4 Msi).

Working with 7095
Is 7095 easy to machine?
Machines well in T6/T7x with sharp carbide tooling, high speed and flood coolant; chips are short and residual-stress distortion is small in stress-relieved 51 tempers.
Can 7095 be welded?
Not fusion weldable (hot cracking, loss of temper); join by riveting, bolting or friction stir welding with post-weld property knock-down accounted for.
Can 7095 be formed, bent or molded?
Form in O or freshly quenched W condition then age; peak-aged plate tolerates only large-radius bending and gentle stretch forming.

Is 7095 easy to machine?
Yes — machinability is rated very good (70/100, better than 72% of aluminum grades). Machines well in T6/T7x with sharp carbide tooling, high speed and flood coolant; chips are short and residual-stress distortion is small in stress-relieved 51 tempers.
Can 7095 be welded?

What is the maximum service temperature of 7095?
7095 is rated for continuous use to about 120°C (248 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 7095-T651 and 7095-O?
T651 is the default condition — standard peak-aged, low-residual-stress plate condition for machined thick aerospace structure. O: softest condition, supplied for deep forming or machining before re-solution treatment. Yield strength is 675 MPa in T651 versus 115 MPa in O.
How much does 7095 cost?
