Titanium Grade 1 vs Ti Grade 11
Titanium · grade comparison
Titanium Grade 1 and Ti Grade 11 are both titanium grades. Both yield at about 220 MPa — strength does not separate them. On the shop floor, Ti Grade 11 sits in a lower cost tier (high, $$$$) than Grade 1 (specialty, $$$$$).
Ti Grade 11Choose it when cost is the deciding factor.
Grade 1 vs Ti Grade 11: 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.
