Titanium Grade 1 vs Ti Grade 30
Titanium · grade comparison
Titanium Grade 1 and Ti Grade 30 are both titanium grades. Ti Grade 30 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 220 MPa (31.9 ksi) for Grade 1, about 50% more; tensile strength follows at 440 MPa (63.8 ksi) vs 300 MPa (43.5 ksi). Ti Grade 30 is harder — 160 HB against 120 HB for Grade 1 — which matters for wear surfaces and threads. Grade 1 conducts heat better (20 W/m·K vs 16.5 W/m·K). On the shop floor, Grade 1 forms better (82 vs 70 out of 100) and Ti Grade 30 sits in a lower cost tier (high, $$$$) than Grade 1 (specialty, $$$$$).
Ti Grade 30Choose it when strength drives the design, or when surface hardness matters.
Grade 1 vs Ti Grade 30: 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 1 vs Ti Grade 30 — frequently asked
Is Ti Grade 30 stronger than Grade 1?
Yes. Ti Grade 30 has a typical yield strength of 330 MPa (47.9 ksi) against 220 MPa (31.9 ksi) for Grade 1 — about 50% more. Tensile strength is 440 MPa (63.8 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, Grade 1 or Ti Grade 30?
Ti Grade 30 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.
Which is easier to machine, Grade 1 or Ti Grade 30?
Grade 1, by a small margin. Both rate fair for machinability — 42/100 against 35/100 for Ti Grade 30; for welding the order is Grade 1 first (excellent, 90/100) then Ti Grade 30 (excellent, 85/100).
