Copper Alloy C10100 vs Cu-HCP
Copper Alloy · grade comparison
Copper Alloy C10100 and Cu-HCP are both copper alloy grades. Both yield at about 69 MPa — strength does not separate them. C10100 is harder — 45 HB against 42 HB for Cu-HCP — which matters for wear surfaces and threads. On the shop floor, Cu-HCP sits in a lower cost tier (high, $$$$) than C10100 (specialty, $$$$$).
C10100Choose it when surface hardness matters.
Cu-HCPChoose it when cost is the deciding factor.
C10100 vs Cu-HCP: 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-HCP — frequently asked
What is the difference between C10100 and Cu-HCP?
Copper Alloy C10100 and Cu-HCP are both copper alloy grades. Both yield at about 69 MPa — strength does not separate them. C10100 is harder — 45 HB against 42 HB for Cu-HCP — which matters for wear surfaces and threads.
Which is cheaper, C10100 or Cu-HCP?
Cu-HCP 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 is easier to machine, C10100 or Cu-HCP?
Cu-HCP, by a small margin. Both rate poor for machinability — 25/100 against 18/100 for C10100; for welding the order is Cu-HCP first (very good, 75/100) then C10100 (very good, 70/100).
