What are different grades of titanium?

- Oct 28, 2019-

CP Titanium – Commercially Pure Titanium

Titanium CP4 – Grade 1

Commercially Pure 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 CP1 – Grade 4

Commercially Pure 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 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.



Chemical Processing, Desalination, Power generation


Titanium Grade 11 – CP Ti-0.15Pd

Titanium Grade 11 is highly resistant to corrosion has similar physical and mechanical properties to Titanium CP Grade 2.

Titanium Grade 19 – Titanium Beta C

Titanium Grade 19 has very high strength and can be heat treated. It offers good resistance to stress and corrosion.


Aerospace Automobile 


Titanium Grade 23 – Titanium 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.
