Titanium Grade 3 vs Ti Grade 11

Titanium · grade comparison

Titanium Grade 3 and Ti Grade 11 are both titanium grades. Grade 3 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 210 MPa (30.5 ksi) for Ti Grade 11, about 100% more; tensile strength follows at 500 MPa (72.5 ksi) vs 300 MPa (43.5 ksi). In exchange, Ti Grade 11 is the more ductile: elongation 32% versus 20% for Grade 3, and Grade 3 is harder (200 HB vs 120 HB). Ti Grade 11 conducts heat better (20 W/m·K vs 16.4 W/m·K). On the shop floor, Ti Grade 11 sits in a lower cost tier (high, $$$$) than Grade 3 (specialty, $$$$$).

Grade 3Choose it when strength drives the design.

Ti Grade 11Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
