Titanium Grade 2 vs Ti Grade 11

Titanium · grade comparison

Titanium Grade 2 and Ti Grade 11 are both titanium grades. Grade 2 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 210 MPa (30.5 ksi) for Ti Grade 11, about 81% more; tensile strength follows at 440 MPa (63.8 ksi) vs 300 MPa (43.5 ksi). In exchange, Ti Grade 11 is the more ductile: elongation 32% versus 28% for Grade 2, and Grade 2 is harder (150 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, $$$$) than Grade 2 (specialty, $$$$$).

Grade 2Choose 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.

Grade 2 vs Ti Grade 11 — frequently asked

Is Grade 2 stronger than Ti Grade 11?

Yes. Grade 2 has a typical yield strength of 380 MPa (55.1 ksi) against 210 MPa (30.5 ksi) for Ti Grade 11 — about 81% more. Tensile strength is 440 MPa (63.8 ksi) vs 300 MPa (43.5 ksi).

Which is cheaper, Grade 2 or Ti Grade 11?

Ti Grade 11 is the lower-cost material: it sits in the high tier ($$$$) while Grade 2 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

When should I choose Grade 2 over Ti Grade 11?

Pick Grade 2 when strength drives the design. Pick Ti Grade 11 when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
