Nickel Alloy Incoloy 800 vs Inconel 600
Nickel Alloy · grade comparison
Nickel Alloy Incoloy 800 and Inconel 600 are both nickel alloy grades. Both yield at about 250 MPa — strength does not separate them. Inconel 600 is harder — 150 HB against 140 HB for Incoloy 800 — which matters for wear surfaces and threads. Incoloy 800 is lighter (7.94 g/cm³ vs 8.47 g/cm³ for Inconel 600) and Inconel 600 is stiffer (214 GPa vs 196 GPa).
Incoloy 800Choose it when weight is the constraint.
Inconel 600Choose it when surface hardness matters, or when the part sees heat.
Incoloy 800 vs Inconel 600: 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.

Incoloy 800 vs Inconel 600 — frequently asked
What is the difference between Incoloy 800 and Inconel 600?
Nickel Alloy Incoloy 800 and Inconel 600 are both nickel alloy grades. Both yield at about 250 MPa — strength does not separate them. Inconel 600 is harder — 150 HB against 140 HB for Incoloy 800 — which matters for wear surfaces and threads.
Which is cheaper, Incoloy 800 or Inconel 600?
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 Incoloy 800 over Inconel 600?
Pick Incoloy 800 when weight is the constraint. Pick Inconel 600 when surface hardness matters, or when the part sees heat.
