TIG Titanium Alloys

Grade 1 is the softest titanium and has the highest ductility. It has excellent corrosion and oxidation resistance. It also has excellent welding properties and high impact toughness. Used in chemical industry, naval and aeronautic applications.

Similar to grade 1 but with higher oxygen content. Often called the workhorse of titanium alloys and is slightly stronger than grade 1 but equally corrosion resistant.

Al and V alloyed Titanium. Titanium Grade 5 is the most commercially available of all titanium alloys. It offers an excellent combination of high strength and toughness. 

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.

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.

Grade 12 is an intermediate strength grade originally developed to provide enhanced crevice-corrosion resistance in high temperature brines, but at lower cost than Grade 7. Grade 12 has better elevated temperature properties than Grade 2 and is sometimes specified for pressure vessels or piping for its superior strength alone.

Titanium Grade 23 is similar to Grade 5 but has lower oxygen, nitrogen and iron levels. However it has higher fracture toughness and better ductility than grade 5.
