Nickel Alloy 601GC vs Inconel 601
Nickel Alloy · grade comparison
Nickel Alloy 601GC and Inconel 601 are both nickel alloy grades. Both yield at about 310 MPa — strength does not separate them. 601GC is harder — 170 HB against 150 HB for Inconel 601 — which matters for wear surfaces and threads.
601GCChoose it when surface hardness matters.
601GC vs Inconel 601: 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.

601GC vs Inconel 601 — frequently asked
What is the difference between 601GC and Inconel 601?
Nickel Alloy 601GC and Inconel 601 are both nickel alloy grades. Both yield at about 310 MPa — strength does not separate them. 601GC is harder — 170 HB against 150 HB for Inconel 601 — which matters for wear surfaces and threads.
Which is cheaper, 601GC or Inconel 601?
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, 601GC or Inconel 601?
Inconel 601, by a small margin. Both rate poor for machinability — 28/100 against 22/100 for 601GC; for welding the order is 601GC first (excellent, 85/100) then Inconel 601 (very good, 78/100).
