Copper Alloy C95500 vs CC212E
Copper Alloy · grade comparison
Copper Alloy C95500 and CC212E are both copper alloy grades. CC212E is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 300 MPa (43.5 ksi) for C95500, about 7% more. CC212E is the more ductile: elongation 25% versus 8% for C95500, and C95500 is harder (192 HB vs 180 HB). C95500 runs hotter in service (300°C vs 250°C continuous) and C95500 conducts heat better (42 W/m·K vs 21 W/m·K). On the shop floor, CC212E welds better (very good vs good) and CC212E sits in a lower cost tier (high, $$$$) than C95500 (specialty, $$$$$).

C95500 vs CC212E: 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.

C95500 vs CC212E — frequently asked
Is CC212E stronger than C95500?
Yes. CC212E has a typical yield strength of 320 MPa (46.4 ksi) against 300 MPa (43.5 ksi) for C95500 — about 7% more. Tensile strength is 700 MPa (102 ksi) vs 700 MPa (102 ksi).
Which is cheaper, C95500 or CC212E?
CC212E is the lower-cost material: it sits in the high tier ($$$$) while C95500 is specialty ($$$$$). 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, C95500 or CC212E?
CC212E, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for C95500; for welding the order is CC212E first (very good, 70/100) then C95500 (good, 60/100).
