Ti-6Al-4V Annealed
VerifiedmetalTi-6Al-4V annealed is a two-phase titanium alloy (6% aluminum, 4% vanadium) in a stress-relieved condition offering moderate strength with improved ductility and fracture toughness compared to higher-strength tempers. Widely used in aerospace engine casings, compressor blades, and airframe components where operating temperatures to 300°C and damage tolerance are critical; available in forgings, extrusions, castings, and wrought forms per MIL specifications.

Quality & Standards
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
