Nickel Alloy CX2MW vs CZ-100
Nickel Alloy · grade comparison
Nickel Alloy CX2MW and CZ-100 are both nickel alloy grades. CX2MW is the stronger of the two: yield strength 335 MPa (48.6 ksi) against 160 MPa (23.2 ksi) for CZ-100, about 109% more; tensile strength follows at 620 MPa (89.9 ksi) vs 380 MPa (55.1 ksi). CX2MW is the more ductile: elongation 45% versus 25% for CZ-100, and CX2MW is harder (200 HB vs 110 HB). CX2MW is stiffer (200 GPa vs 180 GPa) and CX2MW runs hotter in service (675°C vs 480°C continuous). On the shop floor, CZ-100 machines more easily (fair vs poor) and CX2MW welds better (very good vs good).
CX2MWChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
CZ-100Choose it when the part is machined in volume.
CX2MW 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.

CX2MW vs CZ-100 — frequently asked
Is CX2MW stronger than CZ-100?
Yes. CX2MW has a typical yield strength of 335 MPa (48.6 ksi) against 160 MPa (23.2 ksi) for CZ-100 — about 109% more. Tensile strength is 620 MPa (89.9 ksi) vs 380 MPa (55.1 ksi).
Which is cheaper, CX2MW 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, CX2MW or CZ-100?
CZ-100. Its machinability rates fair (35/100) against poor (15/100) for CX2MW; for welding the order is CX2MW first (very good, 75/100) then CZ-100 (good, 60/100).
