2, Titanium Properties and Applications
Commercially Pure Titanium Grades
Grade 1(CP Ti): 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.
Applications: Architecture, Automotive Desalination, Dimensional Stable Anodes, Medical, Marine, Processing & Chlorate Manufacturing
Grade 2(CP Ti): Commercially Pure Titanium Grade 2 has moderate strength and excellent cold forming properties. It provides excellent welding properties and has excellent resistance to oxidation and corrosion.
Applications: Aerospace, Automotive, Chemical Processing & Chlorate Manufacturing, Desalination, Architecture, Hydro Carbon Processing, Marine, Medical, Power Generation
Grade 3(CP Ti): Commercially Pure 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.
Applications: Aerospace, Architecture, Automotive, Chemical Processing & Chlorate Manufacturing, Desalination, Hydro Carbon Processing, Marine, Medical, Power Generation, etc.
Titanium Alloys
Grade 5(Ti-6AL4V): 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.
Applications: Aerospace, Chemical Processing, Marine, Medical, Automotive, Bicycle, Sports, etc.
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.
Applications: Chemical Processing, Desalination, Power generation, etc.
Grade 9: 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.
Applications: Aerospace, Chemical processing, Consumer applications, Marine, Medical, Transportation, Automotive, Bicycle, Sports, etc.
Grade 12: This 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.
Applications: Chemical processing, Desalination, Power generation, Industrial, etc.
