Titanium Grade 1 vs Ti Grade 14
Titanium · grade comparison
Titanium Grade 1 and Ti Grade 14 are both titanium grades. Ti Grade 14 is the stronger of the two: yield strength 360 MPa (52.2 ksi) against 220 MPa (31.9 ksi) for Grade 1, about 64% more; tensile strength follows at 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi). In exchange, Grade 1 is the more ductile: elongation 30% versus 25% for Ti Grade 14, and Ti Grade 14 is harder (160 HB vs 120 HB). Grade 1 conducts heat better (20 W/m·K vs 16.5 W/m·K). On the shop floor, Grade 1 machines more easily (fair vs poor) and Ti Grade 14 sits in a lower cost tier (high, $$$$) than Grade 1 (specialty, $$$$$).
Grade 1Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Ti Grade 14Choose it when strength drives the design, or when cost is the deciding factor.
Grade 1 vs Ti Grade 14: 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 14 — frequently asked
Is Ti Grade 14 stronger than Grade 1?
Yes. Ti Grade 14 has a typical yield strength of 360 MPa (52.2 ksi) against 220 MPa (31.9 ksi) for Grade 1 — about 64% more. Tensile strength is 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, Grade 1 or Ti Grade 14?
Ti Grade 14 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 14?
Grade 1. Its machinability rates fair (42/100) against poor (32/100) for Ti Grade 14; for welding the order is Grade 1 first (excellent, 90/100) then Ti Grade 14 (excellent, 85/100).
