What is Ti-6Al-4V ELI and why is it preferred for critical applications?
Ti-6Al-4V ELI (Extra Low Interstitial) is a premium grade titanium alloy with reduced oxygen, nitrogen, and iron content, offering superior fracture toughness and ductility. This makes it ideal for aerospace, medical implants, and cryogenic applications where reliability and performance are critical. The ELI grade provides enhanced fatigue resistance and low-temperature toughness compared to standard Ti-6Al-4V.
What is STA heat treatment and how does it enhance titanium properties?
STA (Solution Treated and Aged) is a two-step heat treatment process that significantly enhances the mechanical properties of Ti-6Al-4V. Solution treatment at high temperature followed by controlled aging creates a fine microstructure that provides optimal strength, toughness, and fatigue resistance. This process is essential for aerospace components requiring maximum performance and reliability.
What forms of Ti-6Al-4V ELI titanium products do you manufacture?
We manufacture a comprehensive range of Ti-6Al-4V ELI products including sheet, plate, forgings (stock, block, bar, and die), extruded bar and shapes, and titanium ingot. All products are available with STA or annealed heat treatment and meet AMS, MIL-T, and BMS specifications for aerospace and critical applications.
What specifications do your Ti-6Al-4V products meet?
Our Ti-6Al-4V products meet multiple industry specifications including AMS 4911, AMS 4928, AMS 4935, AMS 6930, MIL-T-9046, MIL-T-9047, and BMS 7-247. Each specification is tailored for specific applications and forms, ensuring compliance with aerospace, military, and commercial aviation requirements.
Why choose Ti-6Al-4V for aerospace applications?
Ti-6Al-4V offers an exceptional strength-to-weight ratio, excellent corrosion resistance, and maintains mechanical properties at elevated temperatures up to 400°C (750°F). This combination makes it the most widely used titanium alloy in aerospace, accounting for more than 50% of all titanium tonnage used in aircraft structures, engines, and landing gear components.
