Solution-Treated and Aged Grade 5 Titanium
Solution-treated and aged grade 5 titanium is grade 5 titanium in the annealed and aged condition. The graph bars on the material properties cards below compare solution-treated and aged grade 5 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.
