Grade 23 Ti-6Al-4V ELI Titanium Foil
Ti-6Al-4V ELI (Extra Low Interstitials) is a highly refined titanium alloy, widely recognized as one of the most commonly used titanium alloys.
Description
Ti-6Al-4V is named after the approximately 6% aluminium (Al) and 4% vanadium (V) content, while the ELI suffix emphasizes its extra low content of interstitials (e.g., carbon and nitrogen), which further optimizes its ductility and crack resistance, especially in welding and biomedical applications.
Industry-leading Grade 23 titanium metal foil production technology

Chemical Composition
The chemical composition of grade 23 Ti 6Al 4V ELI alloy is outlined in the following table.
| Element | Content (%) |
|---|---|
| Titanium, Ti | 88.09 - 91 |
| Aluminum, Al | 5.5 - 6.5 |
| Vanadium, V | 3.5 - 4.5 |
| Iron, Fe | ≤ 0.25 |
| Carbon, C | ≤ 0.080 |
| Nitrogen, N | ≤ 0.030 |
| Hydrogen, H | ≤ 0.0125 |
| Other, each | ≤ 0.10 |
| Other, total | ≤ 0.40 |
Advantages
1. Excellent mechanical properties: Combining high strength with good toughness, Ti-6Al-4V ELI stands out from many other alloys for environments where high pressures and dynamic loads are required.
2. excellent corrosion resistance: like all titanium alloys, it is highly resistant to a wide range of corrosive media, making it particularly suitable for offshore and chemical industry applications.
3. excellent biocompatibility: the purification of the ELI grade reduces the number of elements that can cause biological reactions, making it the material of choice for implants such as bone fixation and joint replacement components.
4. Excellent weldability: The low interstitial element content makes the alloy less prone to cracking during welding and facilitates machining into complex shaped components.
