Nickel Alloy Inconel 600 vs Inconel 601
Nickel Alloy · grade comparison
Nickel Alloy Inconel 600 and Inconel 601 are both nickel alloy grades. Inconel 601 is the stronger of the two: yield strength 310 MPa (45 ksi) against 255 MPa (37 ksi) for Inconel 600, about 22% more; tensile strength follows at 690 MPa (100 ksi) vs 620 MPa (89.9 ksi). Inconel 601 is lighter (8.11 g/cm³ vs 8.47 g/cm³ for Inconel 600) and Inconel 600 conducts heat better (14.9 W/m·K vs 11.2 W/m·K).
Inconel 601Choose it when strength drives the design, or when weight is the constraint.
Inconel 600 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.

Inconel 600 vs Inconel 601 — frequently asked
Is Inconel 601 stronger than Inconel 600?
Yes. Inconel 601 has a typical yield strength of 310 MPa (45 ksi) against 255 MPa (37 ksi) for Inconel 600 — about 22% more. Tensile strength is 690 MPa (100 ksi) vs 620 MPa (89.9 ksi).
Which is cheaper, Inconel 600 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.
When should I choose Inconel 600 over Inconel 601?
Pick Inconel 601 when strength drives the design, or when weight is the constraint.
