Copper Alloy CC751S vs CC752S
Copper Alloy · grade comparison
Copper Alloy CC751S and CC752S are both copper alloy grades. CC752S is the stronger of the two: yield strength 110 MPa (16 ksi) against 90 MPa (13.1 ksi) for CC751S, about 22% more; tensile strength follows at 280 MPa (40.6 ksi) vs 220 MPa (31.9 ksi). CC752S is harder — 75 HB against 55 HB for CC751S — which matters for wear surfaces and threads. CC752S is stiffer (95 GPa vs 90 GPa) and CC752S conducts electricity better (24 % IACS vs 20 % IACS). On the shop floor, CC751S sits in a lower cost tier (premium, $$$) than CC752S (high, $$$$).
CC751SChoose it when cost is the deciding factor.
CC752SChoose it when strength drives the design, or when surface hardness matters.
CC751S vs CC752S: 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.
