Nickel 200 vs Nickel 205
Nickel Alloy · grade comparison
Nickel 200 and Nickel 205 are both nickel alloy grades. Both yield at about 148 MPa — strength does not separate them. Nickel 200 is harder — 109 HB against 95 HB for Nickel 205 — which matters for wear surfaces and threads. On the shop floor, Nickel 200 sits in a lower cost tier (premium, $$$) than Nickel 205 (high, $$$$).
Nickel 200Choose it when surface hardness matters, or when cost is the deciding factor.
Nickel 200 vs Nickel 205: 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.
