Nickel Alloy CW-12MW vs IN-713C
Nickel Alloy · grade comparison
Nickel Alloy CW-12MW and IN-713C are both nickel alloy grades. IN-713C is the stronger of the two: yield strength 740 MPa (107 ksi) against 350 MPa (50.8 ksi) for CW-12MW, about 111% more; tensile strength follows at 850 MPa (123 ksi) vs 550 MPa (79.8 ksi). In exchange, CW-12MW is the more ductile: elongation 10% versus 8% for IN-713C, and IN-713C is harder (330 HB vs 200 HB). IN-713C is lighter (7.91 g/cm³ vs 8.94 g/cm³ for CW-12MW) and IN-713C runs hotter in service (950°C vs 650°C continuous). 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.
IN-713CChoose it when strength drives the design, or when weight is the constraint.
CW-12MW vs IN-713C: 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 IN-713C — frequently asked
Is IN-713C stronger than CW-12MW?
Yes. IN-713C has a typical yield strength of 740 MPa (107 ksi) against 350 MPa (50.8 ksi) for CW-12MW — about 111% more. Tensile strength is 850 MPa (123 ksi) vs 550 MPa (79.8 ksi).
Which is cheaper, CW-12MW or IN-713C?
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 IN-713C?
CW-12MW. Its machinability rates poor (22/100) against not recommended (10/100) for IN-713C; for welding the order is CW-12MW first (good, 55/100) then IN-713C (not recommended, 10/100).
