Refractory Metal Mo-41Re vs TZC
Refractory Metal · grade comparison
Refractory Metal Mo-41Re and TZC are both refractory metal grades. Both yield at about 900 MPa — strength does not separate them. Mo-41Re is the more ductile: elongation 15% versus 8% for TZC, and Mo-41Re is harder (33 HRC vs 30 HRC). TZC is lighter (10.05 g/cm³ vs 13.6 g/cm³ for Mo-41Re) and Mo-41Re is stiffer (360 GPa vs 315 GPa). On the shop floor, TZC machines more easily (32 vs 22 out of 100) and Mo-41Re welds better (very good vs poor).
Mo-41ReChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
TZCChoose it when weight is the constraint, or when the part sees heat.
Mo-41Re vs TZC: 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-41Re vs TZC — frequently asked
What is the difference between Mo-41Re and TZC?
Refractory Metal Mo-41Re and TZC are both refractory metal grades. Both yield at about 900 MPa — strength does not separate them. Mo-41Re is the more ductile: elongation 15% versus 8% for TZC, and Mo-41Re is harder (33 HRC vs 30 HRC).
Which is cheaper, Mo-41Re or TZC?
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.
Which is easier to machine, Mo-41Re or TZC?
TZC, by a small margin. Both rate poor for machinability — 32/100 against 22/100 for Mo-41Re; for welding the order is Mo-41Re first (very good, 70/100) then TZC (poor, 15/100).
