Titanium Grade 1（CP4）

Titanium Grade 1 is the softest titanium and has the highest ductility. It has good cold forming characteristics and provides excellent corrosion resistance. It also has excellent welding properties and high impact toughness.

Titanium Grade 2 (CP3)

Titanium Grade 2 has moderate strength and excellent cold forming properties. It provides excellent welding properties and has excellent resistance to oxidation and corrosion.

Titanium Grade 3 (CP2)

Titanium Grade 3 is stronger and less formable than Titanium Grades 1 and 2. It is used in Aerospace and industrial applications that require moderate strength. Grade 3 titanium has excellent corrosion resistance.

Titanium Grade 4 (CP1)

Titanium Grade 4 is stronger than CP Grades 2 & 3 – it can be cold formed, but has lower ductility. It has excellent corrosion resistance in a wide variety of environments. Grade 4 titanium is commonly used in Aerospace, Industrial and Medical applications where high strength is needed.

Titanium Grade 5 (Ti-6AL-4V)

Titanium Grade 5 alloy is the most commercially available of all titanium alloys. It offers an excellent combination of high strength and toughness. Grade 5 titanium has good welding and fabrication characteristics.

Titanium Grade 7

Titanium Grade 7 has physical and mechanical properties equivalent to CP3 titanium or Grade 2. It has excellent welding and fabrication properties and is extremely resistant to corrosion especially from reducing acids.

Titanium Grade 9 (Ti-3AL-2.5V)

Titanium Grade 9 has medium strength that falls between Grade 4 and Grade 5. It has excellent corrosion resistance and is used in Aerospace and Industrial applications. Grade 9 Titanium can be used at higher temperatures than Grades 1 through 4. Grade 9 titanium has good cold rolling properties.

Titanium Grade 12(Ti-0.3Mo-0.8Ni)

Titanium Grade 12 alloy is similar to Titanium Grades 2 and 3 except that Titanium Grade 12 has 0.3% molybdenum and 0.8% nickel. This offers enhanced corrosion resistance.

Titanium Grade 23(Ti-6AL-4V ELI)

Titanium Grade 23 is similar to Grade 5 but has lower oxygen, nitrogen and iron. It has better ductility and fracture toughness than Titanium Grade 5.

Titanium 6-2-4-2 (Ti-6AL-2Sn-4Zr-2Mo)

Titanium 6-2-4-2 has excellent strength, stability, and creep resistance to temperatures as high as 550 °C.
