Titanium Grade 5 and Grade 23
Jan 19, 2026
Titanium Grade 5 and Grade 23 are high-performance titanium alloys widely recognized for their exceptional strength, corrosion resistance, and biocompatibility. Both grades are part of the Ti-6Al-4V family and share similar properties, with Grade 23 being a specialized variant for medical and implant applications.
Key Features of Titanium Grade 5
High Strength-to-Weight Ratio: Offers excellent mechanical strength while remaining lightweight.
Corrosion Resistance: Exceptional resistance to corrosive environments, including seawater and industrial chemicals.
Versatility: Excellent machinability and weldability, making it suitable for complex designs.
Thermal Stability: Can operate at temperatures up to 400°C (752°F).
Wear Resistance: Superior to commercially pure titanium grades, suitable for demanding applications.

Titanium Grade 23 (Ti-6Al-4V ELI): For Medical Applications
Titanium Grade 23, also known as Ti-6Al-4V ELI (Extra Low Interstitial), is a variant of Grade 5 specifically designed for applications requiring superior biocompatibility and lower levels of impurities. It is primarily used in medical, dental, and aerospace applications.




Key Features of Titanium Grade 23
Biocompatibility: Meets stringent medical standards, making it ideal for implants and surgical instruments.
Low Impurity Levels: Extra low interstitial elements improve ductility and fracture toughness.
Corrosion Resistance: Exceptional resistance to body fluids, preventing reactions and corrosion.
Fatigue Strength: Excellent resistance to fatigue under cyclic loading, crucial for medical implants.
Ease of Sterilization: Can withstand multiple sterilization cycles without degradation.

Our factory
We are a specialized manufacturer engaged in the deep processing of titanium and titanium alloys, offering a full product range including titanium tubes, plates, bars, wires, and foils. Our facility is equipped with modern, dedicated production lines featuring heavy-duty reversing hot rolling mills for thick plates and multi-roll cold rolling mills for precision sheets and foils. Tube manufacturing utilizes precision cold pilger mills and seamless tube production lines, while bar and wire products are formed through high-speed bar/wire rolling mills and continuous drawing equipment. Critical processes are supported by vacuum annealing furnaces for precise heat treatment, and finishing is handled by CNC machining centers, laser cutting systems, and precision leveling machines. With a comprehensive quality control system overseeing the entire process from raw material to finished product, we are committed to providing high-performance, precision titanium solutions for industries such as aerospace, medical devices, chemical processing, and high-end consumer goods.

Titanium product packaging
We implement industrial-grade protective standards, providing customized packaging solutions for each titanium product: tubes and bars are individually secured with anti-rust VCI lining within reinforced wooden crates; plates and foils are interleaved with anti-scratch PE film and packed in heavy-duty corrugated boxes; wires are precision-wound on industrial reels. All packages include desiccant and feature clear product labeling with traceability codes, ensuring that your precision titanium materials are protected from moisture, impact, and abrasion during storage and global logistics, arriving safely at your production line.
