UNS R58150 Titanium (Ti-15Mo)

R58150 titanium is a titanium alloy formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. R58150 is the UNS number for this material. Ti-15Mo is the common industry name.

It has a fairly high density among wrought titaniums. In addition, it has a fairly high melting temperature and a fairly low heat capacity.

The graph bars on the material properties cards below compare R58150 titanium to: wrought titaniums (top), all titanium alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
