Specifications:
Titanium Grade 23 is designated as UNS R56401
Titanium 6Al-4V ELI or Titanium Grade 23, is the higher purity version of Ti 6Al-4V. Titanium Grade 23 has a superior damage tolerance to other alloys. These benefits make Titanium Grade 23 the ultimate dental and medical titanium grade. Titanium 6Al-4V ELI can be used in biomedical applications such as implantable components due to its biocompatibility, good fatigue strength and low modulus.
Titanium Grade 23 is similar to Grade 5 but has lower oxygen, nitrogen and iron. Titanium Grade 23 has better ductility and fracture toughness that Titanium Grade 5. Titanium Grade 23 can be made into coils, strands, wires or flat wires. It’s the top choice for any sort of situation where a combination of high strength, light weight, good corrosion resistance and high toughness are required.
Grade 23 Titanium 6Al-4V ELI alloy Applications:
Surgical implants
Aircraft components
Structural components
Salt water applications
In high pressure cryogenic vessels down to -320°C
In applications requiring excellent fracture toughness and fatigue strength.
ZircoSCM offers Titanium Grade 23 in bar, billet, extrusions, plate, sheet, strip and wire.
