Titanium Grade 13 vs Grade 16
Titanium · grade comparison
Titanium Grade 13 and Grade 16 are both titanium grades. Grade 16 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 240 MPa (34.8 ksi) for Grade 13, about 58% more; tensile strength follows at 485 MPa (70.3 ksi) vs 345 MPa (50 ksi). Grade 16 is harder — 150 HB against 130 HB for Grade 13 — which matters for wear surfaces and threads.
Grade 16Choose it when strength drives the design, or when surface hardness matters.
Grade 13 vs Grade 16: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all titanium grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Grade 13 vs Grade 16 — frequently asked
Is Grade 16 stronger than Grade 13?
Yes. Grade 16 has a typical yield strength of 380 MPa (55.1 ksi) against 240 MPa (34.8 ksi) for Grade 13 — about 58% more. Tensile strength is 485 MPa (70.3 ksi) vs 345 MPa (50 ksi).
Which is cheaper, Grade 13 or Grade 16?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
When should I choose Grade 13 over Grade 16?
Pick Grade 16 when strength drives the design, or when surface hardness matters.
