Refractory Metal Mo-0.5Ti vs TZM
Refractory Metal · grade comparison
Refractory Metal Mo-0.5Ti and TZM are both refractory metal grades. TZM is the stronger of the two: yield strength 760 MPa (110 ksi) against 620 MPa (89.9 ksi) for Mo-0.5Ti, about 23% more; tensile strength follows at 900 MPa (131 ksi) vs 760 MPa (110 ksi). In exchange, Mo-0.5Ti is the more ductile: elongation 20% versus 15% for TZM. On the shop floor, TZM machines more easily (45 vs 35 out of 100) and Mo-0.5Ti sits in a lower cost tier (high, $$$$) than TZM (specialty, $$$$$).
Mo-0.5TiChoose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
TZMChoose it when strength drives the design, or when the part is machined in volume.
Mo-0.5Ti vs TZM: 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.

Mo-0.5Ti vs TZM — frequently asked
Is TZM stronger than Mo-0.5Ti?
Yes. TZM has a typical yield strength of 760 MPa (110 ksi) against 620 MPa (89.9 ksi) for Mo-0.5Ti — about 23% more. Tensile strength is 900 MPa (131 ksi) vs 760 MPa (110 ksi).
Which is cheaper, Mo-0.5Ti or TZM?
Mo-0.5Ti is the lower-cost material: it sits in the high tier ($$$$) while TZM is specialty ($$$$$). 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, Mo-0.5Ti or TZM?
TZM, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for Mo-0.5Ti.
