Titanium rods Gr23 - Ti6Al4V ELI
HEXON offer and supply titanium Gr23 (Ti6Al4V ELI) rods for medical implants (orthopedic implants, bone and joint replacement, dental root implants, surgical clips and cryogenic vessels) and other critical industry where improved ductility, moderate strength and better fracture toughness required (such as aircraft components)
No matter the required specification is ASTM F136, ISO 5832-3 or the both, we control customer’s quality concerns including but not limited to:
● Chemical composition – especially for Fe, O and H
● Mechanical properties – tensile, yield, elongation, reduction of area, bending test
● Microstructure
● Ultrasonic inspection for each rod
● Diameter tolerance measurement
● Straightness measurement
You can find more information of our Gr23 Ti6Al4V ELI rods as listed below.
