Copper Alloy C10100 vs Cu-FRHC
Copper Alloy · grade comparison
Copper Alloy C10100 and Cu-FRHC are both copper alloy grades. Both yield at about 69 MPa — strength does not separate them. Cu-FRHC runs hotter in service (250°C vs 200°C continuous). On the shop floor, C10100 welds better (very good vs poor) and Cu-FRHC sits in a lower cost tier (high, $$$$) than C10100 (specialty, $$$$$).

C10100 vs Cu-FRHC: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all copper 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.

C10100 vs Cu-FRHC — frequently asked
What is the difference between C10100 and Cu-FRHC?
Copper Alloy C10100 and Cu-FRHC are both copper alloy grades. Both yield at about 69 MPa — strength does not separate them. Cu-FRHC runs hotter in service (250°C vs 200°C continuous).
Which is cheaper, C10100 or Cu-FRHC?
Cu-FRHC is the lower-cost material: it sits in the high tier ($$$$) while C10100 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which welds better, C10100 or Cu-FRHC?
C10100. Its weldability rates very good (70/100) against poor (30/100) for Cu-FRHC.
