Titanium Grade 1 vs Ti Grade 13

Titanium · grade comparison

Titanium Grade 1 and Ti Grade 13 are both titanium grades. Ti Grade 13 is the stronger of the two: tensile strength 320 MPa (46.4 ksi) against 300 MPa (43.5 ksi) for Grade 1, about 7% more. Grade 1 conducts electricity better (3.6 % IACS vs 3.1 % IACS). On the shop floor, Ti Grade 13 sits in a lower cost tier (high, $$$$) than Grade 1 (specialty, $$$$$).

Ti Grade 13Choose it when strength drives the design, or when cost is the deciding factor.

Grade 1 vs Ti Grade 13 — frequently asked

Is Ti Grade 13 stronger than Grade 1?

Yes. Ti Grade 13 has a typical tensile strength of 320 MPa (46.4 ksi) against 300 MPa (43.5 ksi) for Grade 1 — about 7% more.

Which is cheaper, Grade 1 or Ti Grade 13?

Ti Grade 13 is the lower-cost material: it sits in the high tier ($$$$) while Grade 1 is specialty ($$$$$). 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 1 over Ti Grade 13?

Pick Ti Grade 13 when strength drives the design, or when cost is the deciding factor.
