Nickel Alloy CW-6MC vs N-12M-1
Nickel Alloy · grade comparison
Nickel Alloy CW-6MC and N-12M-1 are both nickel alloy grades. N-12M-1 is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 315 MPa (45.7 ksi) for CW-6MC, about 17% more; tensile strength follows at 585 MPa (84.8 ksi) vs 550 MPa (79.8 ksi). In exchange, CW-6MC is the more ductile: elongation 40% versus 10% for N-12M-1, and N-12M-1 is harder (200 HB vs 180 HB). CW-6MC is lighter (8.44 g/cm³ vs 9.24 g/cm³ for N-12M-1) and N-12M-1 is stiffer (217 GPa vs 200 GPa). On the shop floor, CW-6MC welds better (excellent vs fair).
CW-6MCChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
N-12M-1Choose it when strength drives the design.
CW-6MC vs N-12M-1: 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-6MC vs N-12M-1 — frequently asked
Is N-12M-1 stronger than CW-6MC?
Yes. N-12M-1 has a typical yield strength of 370 MPa (53.7 ksi) against 315 MPa (45.7 ksi) for CW-6MC — about 17% more. Tensile strength is 585 MPa (84.8 ksi) vs 550 MPa (79.8 ksi).
Which is cheaper, CW-6MC or N-12M-1?
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, CW-6MC or N-12M-1?
CW-6MC. Its weldability rates excellent (85/100) against fair (35/100) for N-12M-1.
