AMS 4930
AMS 4930 Titanium (Ti-6Al-4V ELI): High-Reliability Alloy for Critical Parts
AMS 4930 covers Ti-6Al-4V ELI (Extra-Low Interstitial) in bars, wire, forgings and rings supplied in the annealed condition. Engineers choose it for flight-critical hardware, medical implants, and corrosive service where strength, fracture toughness, and cleanliness (low C, O, N, H) are essential. If you’re comparing sources, we also connect you with vetted AMS 4930 titanium dealers in India for rapid regional supply.
Why Design with AMS 4930?
High strength-to-weight: Aerospace-grade performance with meaningful mass savings
ELI cleanliness: Reduced interstitials → higher ductility and fracture toughness
Corrosion resistance: Excellent in seawater and aggressive industrial media
Biocompatibility: Used widely for implants and surgical instruments
Consistent machinability: Reliable results with proper tooling and coolant
