Titanium Grade 1 vs Ti Grade 32
Titanium · grade comparison
Titanium Grade 1 and Ti Grade 32 are both titanium grades. Ti Grade 32 is the stronger of the two: yield strength 700 MPa (102 ksi) against 220 MPa (31.9 ksi) for Grade 1, about 3.2 times as much; tensile strength follows at 790 MPa (115 ksi) vs 300 MPa (43.5 ksi). In exchange, Grade 1 is the more ductile: elongation 30% versus 15% for Ti Grade 32, and Ti Grade 32 is harder (280 HB vs 120 HB). Ti Grade 32 is stiffer (110 GPa vs 103 GPa) and Ti Grade 32 runs hotter in service (400°C vs 300°C continuous). On the shop floor, Grade 1 machines more easily (fair vs poor) and Ti Grade 32 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 32Choose it when strength drives the design, or when the part sees heat.
Grade 1 vs Ti Grade 32: 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 32 — frequently asked
Is Ti Grade 32 stronger than Grade 1?
Yes. Ti Grade 32 has a typical yield strength of 700 MPa (102 ksi) against 220 MPa (31.9 ksi) for Grade 1 — about 3.2 times as much. Tensile strength is 790 MPa (115 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, Grade 1 or Ti Grade 32?
Ti Grade 32 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 32?
Grade 1. Its machinability rates fair (42/100) against poor (22/100) for Ti Grade 32; for welding the order is Grade 1 first (excellent, 90/100) then Ti Grade 32 (excellent, 85/100).
