Copper Alloy C95500 vs ZCuAl9Mn2
Copper Alloy · grade comparison
Copper Alloy C95500 and ZCuAl9Mn2 are both copper alloy grades. C95500 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 165 MPa (23.9 ksi) for ZCuAl9Mn2, about 82% more; tensile strength follows at 700 MPa (102 ksi) vs 430 MPa (62.4 ksi). In exchange, ZCuAl9Mn2 is the more ductile: elongation 25% versus 8% for C95500, and C95500 is harder (192 HB vs 95 HB). ZCuAl9Mn2 conducts heat better (50 W/m·K vs 42 W/m·K). On the shop floor, ZCuAl9Mn2 welds better (very good vs good) and ZCuAl9Mn2 sits in a lower cost tier (high, $$$$) than C95500 (specialty, $$$$$).
C95500Choose it when strength drives the design.
ZCuAl9Mn2Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C95500 vs ZCuAl9Mn2: 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.
