Refractory Metal R05400 vs T-111
Refractory Metal · grade comparison
Refractory Metal R05400 and T-111 are both refractory metal grades. T-111 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 170 MPa (24.7 ksi) for R05400, about 144% more; tensile strength follows at 550 MPa (79.8 ksi) vs 250 MPa (36.3 ksi). In exchange, R05400 is the more ductile: elongation 35% versus 25% for T-111, and T-111 is harder (220 HB vs 90 HB). T-111 is stiffer (200 GPa vs 186 GPa) and T-111 runs hotter in service (2,200°C vs 300°C continuous).
R05400Choose it when the part is bent, formed or impact-loaded.
T-111Choose it when strength drives the design, or when the part sees heat.
R05400 vs T-111: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all refractory metal 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.

R05400 vs T-111 — frequently asked
Is T-111 stronger than R05400?
Yes. T-111 has a typical yield strength of 415 MPa (60.2 ksi) against 170 MPa (24.7 ksi) for R05400 — about 144% more. Tensile strength is 550 MPa (79.8 ksi) vs 250 MPa (36.3 ksi).
Which is cheaper, R05400 or T-111?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
When should I choose R05400 over T-111?
Pick R05400 when the part is bent, formed or impact-loaded. Pick T-111 when strength drives the design, or when the part sees heat.
