Working with 7095-F
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.
What surface finishes work on 7095?
Chromic/sulphuric anodize, hard anodize or Alodine + epoxy primer for corrosion protection; shot peening is common to improve fatigue and SCC life.

7095-F — frequently asked
What is 7095-F used for?
7095-F is typically used for commercial aircraft wing skins, fuselage panels and high-strength thick plate. In short: highest-strength 7000-series plate; spray-formed aerospace grade; not fusion weldable.
What is the yield strength of 7095-F?
7095-F has a typical yield strength of 250 MPa (36.3 ksi) and a tensile strength of 380 MPa (55.1 ksi) — stronger than 65% of aluminum grades. Strength varies by condition: see the 12 listed tempers.
Is 7095-F easy to machine?
Reasonably — machinability is rated good (55/100, worse than 59% 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-F be welded?
Not readily — weldability is rated poor (20/100). Not fusion weldable (hot cracking, loss of temper); join by riveting, bolting or friction stir welding with post-weld property knock-down accounted for.
What surface finishes work on 7095-F?
Chromic/sulphuric anodize, hard anodize or Alodine + epoxy primer for corrosion protection; shot peening is common to improve fatigue and SCC life.
Can 7095-F 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.
What is the maximum service temperature of 7095-F?
7095-F is rated for continuous use to about 150°C (302 °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.
