Titanium 15-3-3-3 (Ti-15V, R58153)
Titanium 15-3-3-3 is a titanium alloy formulated for primary forming into wrought products. R58153 is the UNS number for this material. Ti-15V is the common industry name.
It can have the highest tensile strength among wrought titaniums. In addition, it has the highest embodied energy and can have a fairly low ductility.
The properties of titanium 15-3-3-3 include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare titanium 15-3-3-3 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.
