Compare all 5 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Thermomechanically controlled processed | Pick the annealed state for cold forming, heavy machining or as blank stock ahead of solution treatment and ageing; strength is lowest at 130 MPa yield but elongation reaches 14%. | 130 | 250 | 14 | 65 HB | 45 % IACS |
Solution treated and naturally aged | Bend, form or rivet in this freshly quenched, naturally aged state shortly after solution treatment, then artificially age to T1; it is not a final service condition. | 250 | 400 | 15 | 105 HB | 31 % IACS |
Cooled from hot working, cold worked and naturally aged | Pick the solution treated and overaged temper for thick load-bearing parts in damp or highly stressed service, trading 10–15% strength for far better stress-corrosion resistance and toughness. | 400 | 480 | 10 | 135 HB | 40 % IACS |
Solution heat treated, cold worked and naturally aged | Use the solution treated and two-step aged temper for sheet and extruded skin parts needing exfoliation resistance while staying near peak strength at 440 MPa yield. | 440 | 510 | 9 | 143 HB | 38 % IACS |
T1Default Cooled from hot working and naturally aged | Choose solution treated and artificially aged to peak strength for machined structural parts at 470 MPa yield; check stress-corrosion sensitivity in the short-transverse direction of thick sections. | 470 | 545 | 8 | 150 HB | 33 % IACS |

What is V95?
V95 (В95) is the Russian standard high-strength Al-Zn-Mg-Cu alloy, functionally equivalent to 7075, supplied in M (annealed), T1, T2, T3, T and AT1 conditions as sheet, plate, extrusions and forgings. It is used for aircraft structure, landing-gear components and high-strength forgings at 470 MPa yield, 545 MPa tensile, 8% elongation and 150 HB, and machines freely (75/100). Corrosion resistance is low (35/100), fusion welding is not practical and service is limited to 120 °C, so clad V95A sheet is preferred for thin skins; 7075 is the direct substitute. V95 has a density of 2.85 g/cm³ (0.103 lb/in³), heavier than 96% of aluminum grades. It melts at 477°C (891 °F). V95 has a yield strength of 470 MPa (68.2 ksi) and a tensile strength of 545 MPa (79 ksi) — stronger than 93% of aluminum grades. Elongation at break is 8% and the elastic modulus is 71 GPa (10.3 Msi).

Chemical & Environmental3
Corrosion resistance is fair (35/100), worse than 85% of aluminum grades.

Producing a kilogram of V95 takes about 210 MJ of energy and emits 12.5 kg of CO₂ — more than 88% of aluminum grades. Typical recycled content is 25%.
Manufacturability8
V95's machinability is very good (75/100, better than 86% of aluminum grades); weldability poor (20/100); formability poor (25/100).

Working with V95
Is V95 easy to machine?
Machinability is very good in T1/T2; mill at high speed with HSS or carbide tooling, use plenty of coolant and lubricant, and watch residual-stress distortion on thin-walled parts by choosing stretched or T2 plate.
Can V95 be welded?
Fusion welding (TIG/MIG) is prone to hot cracking and joint softening, so riveting, bolting and friction stir welding are used in practice; if fusion welding is unavoidable, ER5356 can be used but strength drops significantly.
Can V95 be formed, bent or molded?
T1 material is effectively not cold formable; carry out forming in the M condition or shortly after quenching (T condition) and then artificially age. Hot form at 350–450 °C.

What surface finishes work on V95?
Sulphuric and chromic anodizing and hard anodizing are all possible, with only fair decorative dyeing; aerospace parts normally use a chemical conversion coating plus epoxy primer, and thin sheet is preferably clad (V95A) to improve corrosion resistance.

V95 — frequently asked
What is V95 used for?
V95 is typically used for aircraft structural parts, landing gear components and high-strength forgings. In short: russian 7075 equivalent; high-strength airframe alloy; clad sheet for corrosion.
What is the yield strength of V95?
V95 has a typical yield strength of 470 MPa (68.2 ksi) and a tensile strength of 545 MPa (79 ksi) — stronger than 93% of aluminum grades. Strength varies by condition: see the 5 listed tempers.
Is V95 easy to machine?
Yes — machinability is rated very good (75/100, better than 86% of aluminum grades). Machinability is very good in T1/T2; mill at high speed with HSS or carbide tooling, use plenty of coolant and lubricant, and watch residual-stress distortion on thin-walled parts by choosing stretched or T2 plate.
Can V95 be welded?
Not readily — weldability is rated poor (20/100). Fusion welding (TIG/MIG) is prone to hot cracking and joint softening, so riveting, bolting and friction stir welding are used in practice; if fusion welding is unavoidable, ER5356 can be used but strength drops significantly.
What surface finishes work on V95?
Sulphuric and chromic anodizing and hard anodizing are all possible, with only fair decorative dyeing; aerospace parts normally use a chemical conversion coating plus epoxy primer, and thin sheet is preferably clad (V95A) to improve corrosion resistance.
Can V95 be formed, bent or molded?
T1 material is effectively not cold formable; carry out forming in the M condition or shortly after quenching (T condition) and then artificially age. Hot form at 350–450 °C.
What is the maximum service temperature of V95?
V95 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 V95-T1 and V95-M?
T1 is the default condition — choose solution treated and artificially aged to peak strength for machined structural parts at 470 MPa yield; check stress-corrosion sensitivity in the short-transverse direction of thick sections. M: pick the annealed state for cold forming, heavy machining or as blank stock ahead of solution treatment and ageing; strength is lowest at 130 MPa yield but elongation reaches 14%. Yield strength is 470 MPa in T1 versus 130 MPa in M.
