Titanium Grade 3 vs Ti Grade 3
Titanium · grade comparison
Titanium Grade 3 and Ti Grade 3 are both titanium grades. Both yield at about 420 MPa — strength does not separate them. On the shop floor, Ti Grade 3 sits in a lower cost tier (high, $$$$) than Grade 3 (specialty, $$$$$).

Grade 3 vs Ti Grade 3: 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 3 vs Ti Grade 3 — frequently asked
What is the difference between Grade 3 and Ti Grade 3?
Titanium Grade 3 and Ti Grade 3 are both titanium grades. Both yield at about 420 MPa — strength does not separate them. On the shop floor, Ti Grade 3 sits in a lower cost tier (high, $$$$) than Grade 3 (specialty, $$$$$).
Which is cheaper, Grade 3 or Ti Grade 3?
Ti Grade 3 is the lower-cost material: it sits in the high tier ($$$$) while Grade 3 is specialty ($$$$$). 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 3 or Ti Grade 3?
Grade 3. Its machinability rates fair (35/100) against poor (30/100) for Ti Grade 3.
