Nickel Alloy N06975-ANN vs N06975-CW
Nickel Alloy · N06975 temper comparison
N06975-ANN and N06975-CW are two conditions of the same nickel alloy grade, N06975: ANN (annealed) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. N06975-CW is the stronger of the two: yield strength 700 MPa (102 ksi) against 310 MPa (45 ksi) for N06975-ANN, about 126% more; tensile strength follows at 900 MPa (131 ksi) vs 690 MPa (100 ksi). In exchange, N06975-ANN is the more ductile: elongation 50% versus 20% for N06975-CW, and N06975-CW is harder (250 HB vs 185 HB). N06975-ANN runs hotter in service (540°C vs 425°C continuous).
N06975-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
N06975-CWChoose it when strength drives the design.
N06975-ANN vs N06975-CW: 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.
