Gr5 Gr23 Titanium Tubes
Specifications of Gr5 Gr23 Titanium Tubes
Material: GR.5 (Ti6%AL4%V), GR23(Ti6%AL4%V ELI)
Standard: ASTM B861
Certificate: ISO9001-2008
Product Introduction
High-Strength, Corrosion-Resistant Titanium Alloy Tubing for Critical Applications
Gr5 (Ti-6Al-4V) and Gr23 (Ti-6Al-4V ELI) are advanced titanium alloy grades widely used for high-performance seamless tubing. Both alloys offer an excellent combination of strength, low density, and outstanding corrosion resistance, making them suitable for aerospace, medical, and industrial engineering applications.
Gr23 is the Extra Low Interstitial (ELI) version of Gr5, designed to provide improved ductility, fracture toughness, and superior biocompatibility for medical use.
