GR23 Titanium Plate – Superior High-Strength ASTM F136 Alloy
The GR23 titanium plate is a premium medical-grade alloy, recognized for its superior strength, excellent corrosion resistance, and outstanding biocompatibility. Classified as Ti-6Al-4V ELI (Extra Low Interstitial), this alloy is engineered for surgical implants, orthopedic devices, and high-performance industrial applications where material integrity is critical.
As the ASTM F136 titanium plate standard specifies, this grade meets the strictest requirements for surgical implant applications, providing unmatched toughness and ductility compared to standard Ti-6Al-4V (Grade 5). In the medical industry, this alloy is often referred to as the ultimate medical titanium plate, ensuring reliability for life-critical uses.

Key Advantages of GR23 Titanium Plate
1. Biocompatibility
The GR23 titanium plate offers excellent biocompatibility, ensuring it is safe for direct contact with human tissue and fluids, making it an ideal choice for medical implants.
2. Superior Corrosion Resistance
Protected by a stable titanium oxide film, this alloy resists corrosion in saline, blood plasma, and harsh chemical environments, ensuring durability in both medical and industrial use.
3. High Mechanical Strength
The ASTM F 136 titanium plate delivers high tensile and yield strength, enabling components to withstand demanding conditions without deformation or fracture.
4. Enhanced Ductility
The ELI composition improves ductility, allowing the medical titanium plate to be machined, formed, or bent without cracking.
5. Low Elastic Modulus
Closer to that of human bone, reducing stress shielding in orthopedic implants and promoting better bone healing.
