Nickel Alloy CY-40 vs M-35-1
Nickel Alloy · grade comparison
Nickel Alloy CY-40 and M-35-1 are both nickel alloy grades. CY-40 is the stronger of the two: yield strength 245 MPa (35.5 ksi) against 205 MPa (29.7 ksi) for M-35-1, about 20% more; tensile strength follows at 520 MPa (75.4 ksi) vs 485 MPa (70.3 ksi). CY-40 is harder — 145 HB against 125 HB for M-35-1 — which matters for wear surfaces and threads. CY-40 is lighter (8.45 g/cm³ vs 8.84 g/cm³ for M-35-1) and CY-40 is stiffer (200 GPa vs 150 GPa). On the shop floor, M-35-1 welds better (very good vs good).
CY-40Choose it when strength drives the design, or when surface hardness matters.
M-35-1Choose it when it will be welded.
CY-40 vs M-35-1: 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.

CY-40 vs M-35-1 — frequently asked
Is CY-40 stronger than M-35-1?
Yes. CY-40 has a typical yield strength of 245 MPa (35.5 ksi) against 205 MPa (29.7 ksi) for M-35-1 — about 20% more. Tensile strength is 520 MPa (75.4 ksi) vs 485 MPa (70.3 ksi).
Which is cheaper, CY-40 or M-35-1?
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 welds better, CY-40 or M-35-1?
M-35-1. Its weldability rates very good (72/100) against good (60/100) for CY-40.
