Nickel Alloy CZ-100 vs G-NiCr50Nb
Nickel Alloy · grade comparison
Nickel Alloy CZ-100 and G-NiCr50Nb are both nickel alloy grades. G-NiCr50Nb is the stronger of the two: yield strength 400 MPa (58 ksi) against 160 MPa (23.2 ksi) for CZ-100, about 150% more; tensile strength follows at 580 MPa (84.1 ksi) vs 380 MPa (55.1 ksi). In exchange, CZ-100 is the more ductile: elongation 25% versus 5% for G-NiCr50Nb, and G-NiCr50Nb is harder (240 HB vs 110 HB). G-NiCr50Nb is lighter (7.9 g/cm³ vs 8.85 g/cm³ for CZ-100) and G-NiCr50Nb is stiffer (200 GPa vs 180 GPa). On the shop floor, CZ-100 machines more easily (fair vs not recommended) and CZ-100 welds better (good vs poor).
CZ-100Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
G-NiCr50NbChoose it when strength drives the design, or when weight is the constraint.
CZ-100 vs G-NiCr50Nb: 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.

CZ-100 vs G-NiCr50Nb — frequently asked
Is G-NiCr50Nb stronger than CZ-100?
Yes. G-NiCr50Nb has a typical yield strength of 400 MPa (58 ksi) against 160 MPa (23.2 ksi) for CZ-100 — about 150% more. Tensile strength is 580 MPa (84.1 ksi) vs 380 MPa (55.1 ksi).
Which is cheaper, CZ-100 or G-NiCr50Nb?
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, CZ-100 or G-NiCr50Nb?
CZ-100. Its machinability rates fair (35/100) against not recommended (12/100) for G-NiCr50Nb; for welding the order is CZ-100 first (good, 60/100) then G-NiCr50Nb (poor, 25/100).
