Description
Technical Parameters
Products Description
Grade 23 is the Extra Low Interstitial (ELI) variant of Gr5. With strictly limited oxygen, nitrogen, carbon, hydrogen, and iron, it gains much higher ductility, fracture toughness, and biocompatibility compared to standard Grade 5.It becomes the top choice for life-critical medical implants and cryogenic and aerospace components. It is typically supplied annealed for maximum toughness.
Our company is located in the "China's Titanium Valley". We provide a complete industrial chain for titanium product manufacturing. With a strong reputation in the titanium industry, we are committed to delivering high-quality products through strict quality inspection and control.

Manufacturing & Processing of Gr23 Titanium Wires
Double Vacuum Arc Remelting
Double VAR process is adopted to precisely control interstitial elements and ensure chemical composition uniformity.
Hot Working + Cold Drawing
Use hot working and multi-pass cold drawing to achieve the final specified diameter and apply with intermediate stress-relief annealing between drawing passes to eliminate internal stress.
Final Heat Treatment & Cleaning
Final mill annealing to optimize material ductility and toughness.
Strict surface cleaning procedures implemented to prevent hydrogen absorption and surface contamination.
Quality & Traceability
Full material traceability from raw material to finished product.
Complete MTC provided per batch.
Batch inspection covering chemical composition, mechanical properties, and surface quality.
Key Advantages vs. Grade 5
Higher ductility & fracture toughness : It is safer for implants and fatigue loading.
Superior biocompatibility: It has lower interstitials reduce ion release risk.
Better performance at cryogenic temperatures: It has no ductile-to-brittle transition issues.
Tighter chemistry control for batch-to-batch consistency in regulated industries.

FAQ
Everything You Need to Know
Q: What tempers are available?
A: Annealed (M): Soft, ductile, good for forming.
Cold worked (Y): Higher strength, lower ductility.
Hot rolled (R): Intermediate properties.
Q: What are the packaging and shipping requirements?
A: Usually packed on plastic or metal spools, with anti corrosion paper and wooden crates for bulk shipments to prevent damage during transport.
Q:Can Gr23 wire be welded?
A:Yes, it has good weldability. Use Ti 6Al 4V ELI filler wire and inert gas shielding (argon) to avoid contamination and embrittlement.
