Nickel Alloy Chromel vs NiCr60/16
Nickel Alloy · grade comparison
Nickel Alloy Chromel and NiCr60/16 are both nickel alloy grades. NiCr60/16 is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 275 MPa (39.9 ksi) for Chromel, about 27% more; tensile strength follows at 690 MPa (100 ksi) vs 655 MPa (95 ksi). NiCr60/16 is harder — 180 HB against 150 HB for Chromel — which matters for wear surfaces and threads. NiCr60/16 is lighter (8.2 g/cm³ vs 8.73 g/cm³ for Chromel) and NiCr60/16 is stiffer (210 GPa vs 186 GPa). On the shop floor, Chromel welds better (very good vs good) and Chromel forms better (excellent vs very good).

Chromel vs NiCr60/16: 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.

Chromel vs NiCr60/16 — frequently asked
Is NiCr60/16 stronger than Chromel?
Yes. NiCr60/16 has a typical yield strength of 350 MPa (50.8 ksi) against 275 MPa (39.9 ksi) for Chromel — about 27% more. Tensile strength is 690 MPa (100 ksi) vs 655 MPa (95 ksi).
Which is cheaper, Chromel or NiCr60/16?
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 welds better, Chromel or NiCr60/16?
Chromel. Its weldability rates very good (75/100) against good (62/100) for NiCr60/16.
