Working with V95-M
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-M — frequently asked
What is V95-M used for?
V95-M 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-M?
V95-M has a typical yield strength of 130 MPa (18.9 ksi) and a tensile strength of 250 MPa (36.3 ksi) — weaker than 73% of aluminum grades. Strength varies by condition: see the 5 listed tempers.
Is V95-M easy to machine?
Reasonably — machinability is rated fair (45/100, worse than 72% 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-M 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-M?
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-M 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-M?
V95-M 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.
