Grade 5 (α+β Alloy (Ti-6Al-4V)) — Properties, Specifications & Supply

Grade 5, also known as Ti-6Al-4V (6% aluminum, 4% vanadium), is the most widely used titanium alloy — over 50% of all titanium produced globally. UNS R56400. With 895 MPa tensile strength and excellent fatigue resistance, it's the standard for aerospace fasteners, landing gear, medical implants, and high-performance racing components.

Grade 5 (Ti-6Al-4V) bar stock costs $22–32/kg FOB Baoji for standard commercial quantities (≥100 kg). Sheet runs $30–42/kg. Forgings cost $28–55/kg depending on complexity. Medical-grade (ASTM F136 certified) commands a 15–30% premium.

Yes. Grade 5 (Ti-6Al-4V) is an alpha-beta titanium alloy containing 6% aluminum and 4% vanadium as intentional alloying elements. Unlike commercially pure grades (1-4), it's engineered for high strength-to-weight ratio and is the most common titanium alloy worldwide.

Both are Ti-6Al-4V, but Grade 23 (ELI — Extra Low Interstitials) has tighter limits on oxygen (≤0.13% vs ≤0.20%), iron, and carbon. This gives Grade 23 superior fracture toughness and fatigue life, making it mandatory for medical implants (ASTM F136) and critical aerospace fracture-sensitive parts.
