Nickel Alloy 2.4889 vs NiCr80/20
Nickel Alloy · grade comparison
Nickel Alloy 2.4889 and NiCr80/20 are both nickel alloy grades. 2.4889 is the stronger of the two: tensile strength 760 MPa (110 ksi) against 700 MPa (102 ksi) for NiCr80/20, about 9% more. In exchange, NiCr80/20 is the more ductile: elongation 35% versus 30% for 2.4889, and 2.4889 is harder (170 HB vs 160 HB). 2.4889 is lighter (8.12 g/cm³ vs 8.4 g/cm³ for NiCr80/20) and 2.4889 runs hotter in service (1,250°C vs 1,150°C continuous).
2.4889Choose it when strength drives the design, or when weight is the constraint.
NiCr80/20Choose it when the part is bent, formed or impact-loaded.
2.4889 vs NiCr80/20: 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.

2.4889 vs NiCr80/20 — frequently asked
Is 2.4889 stronger than NiCr80/20?
Yes. 2.4889 has a typical tensile strength of 760 MPa (110 ksi) against 700 MPa (102 ksi) for NiCr80/20 — about 9% more.
Which is cheaper, 2.4889 or NiCr80/20?
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, 2.4889 or NiCr80/20?
NiCr80/20. Its weldability rates very good (72/100) against good (65/100) for 2.4889.
