Titanium Grade 2 vs Ti Grade 26

Titanium · grade comparison

Titanium Grade 2 and Ti Grade 26 are both titanium grades. Grade 2 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 330 MPa (47.9 ksi) for Ti Grade 26, about 15% more. Grade 2 is the more ductile: elongation 28% versus 24% for Ti Grade 26, and Ti Grade 26 is harder (160 HB vs 150 HB). On the shop floor, Ti Grade 26 sits in a lower cost tier (high, $$$$) than Grade 2 (specialty, $$$$$).

Grade 2Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

Ti Grade 26Choose it when cost is the deciding factor.
