Description

Technical Parameters

Products Description

Gr23 titanium sheet, also known as Ti-6Al-4V ELI (Extra Low Interstitial), is a premium α+β titanium alloy with ultra-low interstitial elements (O, N, H, Fe). It is the medical-grade version of Grade 5 (Ti-6Al-4V), engineered for superior toughness, biocompatibility, and weldability in critical applications.

Gr23 titanium is a higher purity variant of the ubiquitous grade 5, specifically formulated with extra low interstitial elements like oxygen, nitrogen and iron. This refinement gives it superior fracture toughness and enhanced ductility compared to standard grade 5, making it the premier choice for the most demanding aerospace and medical applications where reliability and human safety are critical.

FAQ About Gr23 Titanium Sheet

How is Gr23 different from Gr5 (Ti‑6Al‑4V)?

Interstitials: Gr23 has stricter limits on O/N/C/H → higher toughness, better fatigue life.
Biocompatibility: Gr23 is ASTM F136‑certified for long‑term implantation; Gr5 is not recommended for permanent implants.
Weldability: Gr23 welds more reliably with less brittleness at joints.
Cost: Gr23 is more expensive due to stricter purification and testing.

Can Gr23 titanium sheet be welded or machined?

Welding: Yes, use TIG/laser welding. Post‑weld annealing is recommended to relieve stress.
Machining: Possible, but use low speed, high feed, and sharp tools.

What are the limitations of Gr23?

Cost: Higher than Gr5 and pure titanium (Gr1/Gr2).
Strength: Slightly lower than Gr5 in some heat‑treated conditions.
Surface hardness: Lower than steel; prone to scratching without proper coating.

How to store and handle Gr23 titanium sheet?

Store in a dry, clean environment (avoid moisture and dust).
Use gloves when handling to prevent fingerprint contamination.
Package with pearl cotton + wooden case for shipping (anti‑collision, anti‑rust)
