Nickel 200 vs Nickel 201
Nickel Alloy · grade comparison
Nickel 200 and Nickel 201 are both nickel alloy grades. Nickel 200 is the stronger of the two: yield strength 148 MPa (21.5 ksi) against 105 MPa (15.2 ksi) for Nickel 201, about 41% more; tensile strength follows at 462 MPa (67 ksi) vs 415 MPa (60.2 ksi). Nickel 200 is harder — 109 HB against 90 HB for Nickel 201 — which matters for wear surfaces and threads. Nickel 201 runs hotter in service (650°C vs 315°C continuous) and Nickel 201 conducts heat better (79 W/m·K vs 70.2 W/m·K). On the shop floor, Nickel 200 sits in a lower cost tier (premium, $$$) than Nickel 201 (high, $$$$).
Nickel 200Choose it when strength drives the design, or when surface hardness matters.
Nickel 201Choose it when the part sees heat.
Nickel 200 vs Nickel 201: 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.
