Nickel Alloy Monel 401 vs Nickel 200
Nickel Alloy · grade comparison
Nickel Alloy Monel 401 and Nickel 200 are both nickel alloy grades. Monel 401 is the stronger of the two: yield strength 170 MPa (24.7 ksi) against 148 MPa (21.5 ksi) for Nickel 200, about 15% more. In exchange, Nickel 200 is the more ductile: elongation 47% versus 42% for Monel 401, and Monel 401 is harder (115 HB vs 109 HB). Nickel 200 is stiffer (204 GPa vs 160 GPa) and Monel 401 runs hotter in service (425°C vs 315°C continuous). On the shop floor, Nickel 200 welds better (excellent vs good) and Nickel 200 sits in a lower cost tier (premium, $$$) than Monel 401 (high, $$$$).
Monel 401Choose it when strength drives the design, or when the part sees heat.
Nickel 200Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
Monel 401 vs Nickel 200: 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.
