Refractory Metal 60Cr-40Ni vs FeCrSi
Refractory Metal · grade comparison
Refractory Metal 60Cr-40Ni and FeCrSi are both refractory metal grades. 60Cr-40Ni is the stronger of the two: tensile strength 415 MPa (60.2 ksi) against 120 MPa (17.4 ksi) for FeCrSi, about 3.5 times as much. 60Cr-40Ni is the more ductile: elongation 2% versus 0% for FeCrSi, and FeCrSi is harder (65 HRC vs 19 HRC). FeCrSi is lighter (5.2 g/cm³ vs 7.7 g/cm³ for 60Cr-40Ni) and 60Cr-40Ni is stiffer (225 GPa vs 150 GPa). On the shop floor, 60Cr-40Ni welds better (poor vs not recommended) and FeCrSi sits in a lower cost tier (budget, $) than 60Cr-40Ni (high, $$$$).
60Cr-40NiChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
FeCrSiChoose it when weight is the constraint, or when cost is the deciding factor.
60Cr-40Ni vs FeCrSi: 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.

60Cr-40Ni vs FeCrSi — frequently asked
Is 60Cr-40Ni stronger than FeCrSi?
Yes. 60Cr-40Ni has a typical tensile strength of 415 MPa (60.2 ksi) against 120 MPa (17.4 ksi) for FeCrSi — about 3.5 times as much.
Which is cheaper, 60Cr-40Ni or FeCrSi?
FeCrSi is the lower-cost material: it sits in the budget tier ($) while 60Cr-40Ni is high ($$$$). 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, 60Cr-40Ni or FeCrSi?
60Cr-40Ni, by a small margin. Both rate not recommended for machinability — 12/100 against 4/100 for FeCrSi; for welding the order is 60Cr-40Ni first (poor, 20/100) then FeCrSi (not recommended, 0/100).
