Copper Alloy C95500 vs C95700
Copper Alloy · grade comparison
Copper Alloy C95500 and C95700 are both copper alloy grades. C95700 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 300 MPa (43.5 ksi) for C95500, about 10% more. C95700 is the more ductile: elongation 26% versus 8% for C95500, and C95500 is harder (192 HB vs 180 HB). C95500 conducts heat better (42 W/m·K vs 20 W/m·K). On the shop floor, C95700 sits in a lower cost tier (high, $$$$) than C95500 (specialty, $$$$$).
C95700Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C95500 vs C95700: 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.
