Refractory Metal 50Cr-50Ni vs FeCr-HC
Refractory Metal · grade comparison
Refractory Metal 50Cr-50Ni and FeCr-HC are both refractory metal grades. FeCr-HC is harder — 63 HRC against 20 HRC for 50Cr-50Ni — which matters for wear surfaces and threads. FeCr-HC is lighter (7.1 g/cm³ vs 7.85 g/cm³ for 50Cr-50Ni) and 50Cr-50Ni runs hotter in service (1,100°C vs 600°C continuous). On the shop floor, 50Cr-50Ni machines more easily (poor vs not recommended) and FeCr-HC sits in a lower cost tier (budget, $) than 50Cr-50Ni (high, $$$$).
50Cr-50NiChoose it when the part sees heat, or when the part is machined in volume.
FeCr-HCChoose it when surface hardness matters, or when weight is the constraint.
50Cr-50Ni vs FeCr-HC: 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 FeCr-HC — frequently asked
What is the difference between 50Cr-50Ni and FeCr-HC?
Refractory Metal 50Cr-50Ni and FeCr-HC are both refractory metal grades. FeCr-HC is harder — 63 HRC against 20 HRC for 50Cr-50Ni — which matters for wear surfaces and threads. FeCr-HC is lighter (7.1 g/cm³ vs 7.85 g/cm³ for 50Cr-50Ni) and 50Cr-50Ni runs hotter in service (1,100°C vs 600°C continuous).
Which is cheaper, 50Cr-50Ni or FeCr-HC?
FeCr-HC is the lower-cost material: it sits in the budget tier ($) while 50Cr-50Ni is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 50Cr-50Ni or FeCr-HC?
50Cr-50Ni. Its machinability rates poor (15/100) against not recommended (3/100) for FeCr-HC.
