Nickel Alloy Alloy 890 vs CZ-100
Nickel Alloy · grade comparison
Nickel Alloy Alloy 890 and CZ-100 are both nickel alloy grades. Alloy 890 is the stronger of the two: yield strength 200 MPa (29 ksi) against 160 MPa (23.2 ksi) for CZ-100, about 25% more; tensile strength follows at 455 MPa (66 ksi) vs 380 MPa (55.1 ksi). Alloy 890 is the more ductile: elongation 40% versus 25% for CZ-100, and Alloy 890 is harder (160 HB vs 110 HB). Alloy 890 is lighter (7.95 g/cm³ vs 8.85 g/cm³ for CZ-100) and Alloy 890 is stiffer (193 GPa vs 180 GPa). On the shop floor, CZ-100 welds better (good vs fair).
Alloy 890Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
CZ-100Choose it when it will be welded.
Alloy 890 vs CZ-100: 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.

Alloy 890 vs CZ-100 — frequently asked
Is Alloy 890 stronger than CZ-100?
Yes. Alloy 890 has a typical yield strength of 200 MPa (29 ksi) against 160 MPa (23.2 ksi) for CZ-100 — about 25% more. Tensile strength is 455 MPa (66 ksi) vs 380 MPa (55.1 ksi).
Which is cheaper, Alloy 890 or CZ-100?
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, Alloy 890 or CZ-100?
CZ-100. Its machinability rates fair (35/100) against poor (30/100) for Alloy 890; for welding the order is CZ-100 first (good, 60/100) then Alloy 890 (fair, 45/100).
