Copper Alloy C10100 vs CuAg0.07(OF)
Copper Alloy · grade comparison
Copper Alloy C10100 and CuAg0.07(OF) are both copper alloy grades. Both yield at about 69 MPa — strength does not separate them. CuAg0.07(OF) is harder — 55 HV against 50 HV for C10100 — which matters for wear surfaces and threads. CuAg0.07(OF) runs hotter in service (300°C vs 200°C continuous). On the shop floor, C10100 welds better (very good vs good) and CuAg0.07(OF) sits in a lower cost tier (high, $$$$) than C10100 (specialty, $$$$$).

CuAg0.07(OF)Choose it when surface hardness matters, or when the part sees heat.
C10100 vs CuAg0.07(OF): 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.
