Chemical Composition Features
Aluminum (Al)
Aluminum is the primary alpha-phase stabilizer in Ti-6Al-4V, significantly improving strength, hardness, and heat resistance while maintaining a lightweight structure.
Vanadium (V)
Vanadium acts as a beta-phase stabilizer, enhancing toughness, ductility, fatigue resistance, and heat treatment response.
Low Interstitial Elements
Strict control of oxygen, carbon, nitrogen, and hydrogen helps maintain excellent ductility, fracture toughness, weldability, and fatigue performance.
High-Purity Titanium Matrix
The balance of titanium provides exceptional corrosion resistance in seawater, chloride solutions, oxidizing acids, and many harsh industrial environments.

Frequently Asked Questions (FAQ)
Q: What is the main difference between Gr5 Titanium Alloy and Gr2 titanium?
A: Gr5 is an alpha-beta alloy with approximately twice the strength and hardness of commercially pure Gr2 titanium, though with slightly lower formability. Gr5 is selected for applications requiring higher mechanical performance.
Q: Is your Gr5 material compliant with medical implant standards?
A: Yes. We supply ASTM F136 compliant Ti-6Al-4V ELI (Extra Low Interstitial) grade material, specifically designed for surgical implants, offering enhanced fracture toughness and biocompatibility.
Q: Can you supply custom-sized machining stock?
A: Absolutely. Our advanced CNC machining centers allow us to provide finished "ready-to-install" components per your drawings, saving you time and production costs.
