Nickel Alloy CW-12MW vs DZ22
Nickel Alloy · grade comparison
Nickel Alloy CW-12MW and DZ22 are both nickel alloy grades. DZ22 is the stronger of the two: yield strength 850 MPa (123 ksi) against 350 MPa (50.8 ksi) for CW-12MW, about 143% more; tensile strength follows at 980 MPa (142 ksi) vs 550 MPa (79.8 ksi). In exchange, CW-12MW is the more ductile: elongation 10% versus 7% for DZ22, and DZ22 is harder (378 HB vs 200 HB). DZ22 is lighter (8.6 g/cm³ vs 8.94 g/cm³ for CW-12MW) and CW-12MW is stiffer (205 GPa vs 130 GPa). On the shop floor, CW-12MW machines more easily (poor vs not recommended) and CW-12MW welds better (good vs not recommended).
CW-12MWChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
DZ22Choose it when strength drives the design, or when weight is the constraint.
CW-12MW vs DZ22: 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.

CW-12MW vs DZ22 — frequently asked
Is DZ22 stronger than CW-12MW?
Yes. DZ22 has a typical yield strength of 850 MPa (123 ksi) against 350 MPa (50.8 ksi) for CW-12MW — about 143% more. Tensile strength is 980 MPa (142 ksi) vs 550 MPa (79.8 ksi).
Which is cheaper, CW-12MW or DZ22?
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, CW-12MW or DZ22?
CW-12MW. Its machinability rates poor (22/100) against not recommended (8/100) for DZ22; for welding the order is CW-12MW first (good, 55/100) then DZ22 (not recommended, 12/100).
