Nickel Alloy NiCr60/15 vs Nitinol
Nickel Alloy · grade comparison
Nickel Alloy NiCr60/15 and Nitinol are both nickel alloy grades. Nitinol is the stronger of the two: tensile strength 950 MPa (138 ksi) against 690 MPa (100 ksi) for NiCr60/15, about 38% more. Nitinol is harder — 250 HV against 180 HV for NiCr60/15 — which matters for wear surfaces and threads. Nitinol is lighter (6.45 g/cm³ vs 8.24 g/cm³ for NiCr60/15) and NiCr60/15 is stiffer (210 GPa vs 75 GPa). On the shop floor, NiCr60/15 machines more easily (poor vs not recommended), NiCr60/15 welds better (good vs fair), and NiCr60/15 forms better (very good vs fair).
NiCr60/15Choose it when the part sees heat, or when the part is machined in volume.
NitinolChoose it when strength drives the design, or when surface hardness matters.
NiCr60/15 vs Nitinol: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all nickel alloy 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.

NiCr60/15 vs Nitinol — frequently asked
Is Nitinol stronger than NiCr60/15?
Yes. Nitinol has a typical tensile strength of 950 MPa (138 ksi) against 690 MPa (100 ksi) for NiCr60/15 — about 38% more.
Which is cheaper, NiCr60/15 or Nitinol?
Nitinol is the lower-cost material: it sits in the premium tier ($$$) while NiCr60/15 is high ($$$$). 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, NiCr60/15 or Nitinol?
NiCr60/15. Its machinability rates poor (25/100) against not recommended (12/100) for Nitinol; for welding the order is NiCr60/15 first (good, 65/100) then Nitinol (fair, 35/100).
