Nickel Alloy Alloy 602 CA vs Inconel 600
Nickel Alloy · grade comparison
Nickel Alloy Alloy 602 CA and Inconel 600 are both nickel alloy grades. Alloy 602 CA is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 255 MPa (37 ksi) for Inconel 600, about 29% more; tensile strength follows at 750 MPa (109 ksi) vs 620 MPa (89.9 ksi). Alloy 602 CA is harder — 185 HB against 150 HB for Inconel 600 — which matters for wear surfaces and threads. Alloy 602 CA is lighter (7.9 g/cm³ vs 8.47 g/cm³ for Inconel 600) and Alloy 602 CA runs hotter in service (1,200°C vs 1,100°C continuous). On the shop floor, Inconel 600 machines more easily (28 vs 18 out of 100), Inconel 600 welds better (very good vs good), and Inconel 600 forms better (very good vs good).
Alloy 602 CAChoose it when strength drives the design, or when surface hardness matters.
Inconel 600Choose it when the part is machined in volume, or when it will be welded.
Alloy 602 CA 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.

Alloy 602 CA vs Inconel 600 — frequently asked
Is Alloy 602 CA stronger than Inconel 600?
Yes. Alloy 602 CA has a typical yield strength of 330 MPa (47.9 ksi) against 255 MPa (37 ksi) for Inconel 600 — about 29% more. Tensile strength is 750 MPa (109 ksi) vs 620 MPa (89.9 ksi).
Which is cheaper, Alloy 602 CA 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.
Which is easier to machine, Alloy 602 CA or Inconel 600?
Inconel 600, by a small margin. Both rate poor for machinability — 28/100 against 18/100 for Alloy 602 CA; for welding the order is Inconel 600 first (very good, 80/100) then Alloy 602 CA (good, 60/100).
