Grade 1: Pure Titanium, relatively low strength and high ductility.
Grade 2: The pure titanium most used. The best combination of strength
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 application.
