Description
Technical Parameters
Products Introduction
Ti-6Al-4V ELI is also known as Grade 23 titanium alloy plate, the ultra-high-purity variant of standard Ti-6Al-4V (Grade 5).
Titanium plates are thick flat rolled metal panels manufactured from commercially pure titanium (CP Ti) or titanium alloys via hot rolling, cold rolling and heat treatment.
· Standard Ti-6Al-4V: Higher oxygen, nitrogen, hydrogen and iron interstitial limits; high strength, common for aerospace structural parts.
· Ti-6Al-4V ELI: Strictly controlled low interstitial element content (lower O, N, C, H). It delivers superior ductility, fracture toughness, fatigue resistance and cryogenic performance, with slightly lower tensile strength than Grade 5.

FAQ about Ti-6Al-4V ELI Titanium Plates
Where are Ti-6Al-4V ELI titanium plates widely used?
- Medical industry (dominant field): Orthopedic implants, dental frameworks, surgical equipment
- Aerospace & aviation: Cryogenic fuel tank components, aircraft landing gear parts, helicopter structural parts requiring high fatigue toughness
- Deep sea/marine equipment: Subsea pressure vessels, seawater desalination equipment, underwater robot structural plates
- Cryogenic engineering: Liquid gas storage equipment working under ultra-low temperature
- High-end precision equipment: Semiconductor vacuum chamber parts, high-reliability sensor brackets
Why is Ti-6Al-4V ELI plate more expensive than regular Ti-6Al-4V Grade 5 plate?
- Higher raw material cost: Extra low interstitial sponge titanium has stricter smelting control
- Rigorous inspection: Batch oxygen/hydrogen/nitrogen testing required for every plate batch
- Narrow production process window: More precise rolling and annealing parameters
- Lower production yield due to strict impurity limits
When to pick Ti-6Al-4V ELI plate vs pure titanium vs Grade 5 Ti-6Al-4V?
- Medical implant, cryogenic parts, high-fatigue aerospace parts → Ti-6Al-4V ELI Grade 23 plate
- General high-strength aerospace structural parts without strict toughness demand → Ti-6Al-4V Grade 5 plate
- Pure corrosion resistance, soft forming, low load components → Grade 1/2 pure titanium plate
How is the corrosion resistance of Ti-6Al-4V ELI plate?
- Excellent universal corrosion resistance thanks to self-passivating TiO₂ film:
- Fully resistant to seawater, brine, fresh water, mild acids, chlorides
- Resists pitting and crevice corrosion in marine environments
- Not resistant to concentrated hydrofluoric acid and hot strong reducing acids
