Titanium

Titanium Grade 1-4 is pure Titanium, the other grades are alloys. Pure Titanium is used due to its high corrosion resistance, the alloys because of the extremely high strength to weight ratio.

  • Grade 1. Pure Titanium, relatively low strength and high ductility.
  • Grade 2. The pure titanium most used. The best combination of strength, ductility and weld ability.
  • Grade 3. High strength Titanium, used for Matrix-plates in shell and tube heat exchangers.
  • Grade 5. The most manufactured titanium alloy. Exceedingly high strength. High heat resistance.
  • Grade 7. Superior corrosion resistance in reducing and oxidizing environments.
  • Grade 9. Very high strength and corrosion resistance..
  • Grade 12. Better heat resistance than pure Titanium. Applications as for Grade 7 and Grade 11.
  • Grade 23. Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for surgical implant Applications.
