Refractory Metal 50Cr-50Ni vs 60Cr-40Ni
Refractory Metal · grade comparison
Refractory Metal 50Cr-50Ni and 60Cr-40Ni are both refractory metal grades. 50Cr-50Ni is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 310 MPa (45 ksi) for 60Cr-40Ni, about 10% more; tensile strength follows at 550 MPa (79.8 ksi) vs 415 MPa (60.2 ksi). 50Cr-50Ni is the more ductile: elongation 8% versus 2% for 60Cr-40Ni, and 50Cr-50Ni is harder (20 HRC vs 19 HRC). 60Cr-40Ni is stiffer (225 GPa vs 200 GPa) and 50Cr-50Ni conducts electricity better (1.7 % IACS vs 1.5 % IACS).
50Cr-50NiChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
50Cr-50Ni vs 60Cr-40Ni: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all refractory metal 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.

50Cr-50Ni vs 60Cr-40Ni — frequently asked
Is 50Cr-50Ni stronger than 60Cr-40Ni?
Yes. 50Cr-50Ni has a typical yield strength of 340 MPa (49.3 ksi) against 310 MPa (45 ksi) for 60Cr-40Ni — about 10% more. Tensile strength is 550 MPa (79.8 ksi) vs 415 MPa (60.2 ksi).
Which is cheaper, 50Cr-50Ni or 60Cr-40Ni?
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 50Cr-50Ni over 60Cr-40Ni?
Pick 50Cr-50Ni when strength drives the design, or when the part is bent, formed or impact-loaded.
