Copper Alloy C97800 vs CC380H
Copper Alloy · grade comparison
Copper Alloy C97800 and CC380H are both copper alloy grades. C97800 is the stronger of the two: yield strength 225 MPa (32.6 ksi) against 140 MPa (20.3 ksi) for CC380H, about 61% more; tensile strength follows at 400 MPa (58 ksi) vs 300 MPa (43.5 ksi). In exchange, CC380H is the more ductile: elongation 25% versus 15% for C97800, and C97800 is harder (130 HB vs 80 HB). CC380H runs hotter in service (300°C vs 260°C continuous) and CC380H conducts heat better (42 W/m·K vs 25 W/m·K). On the shop floor, C97800 machines more easily (good vs poor) and CC380H welds better (very good vs poor).
C97800Choose it when strength drives the design, or when the part is machined in volume.
CC380HChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C97800 vs CC380H: 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.

C97800 vs CC380H — frequently asked
Is C97800 stronger than CC380H?
Yes. C97800 has a typical yield strength of 225 MPa (32.6 ksi) against 140 MPa (20.3 ksi) for CC380H — about 61% more. Tensile strength is 400 MPa (58 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, C97800 or CC380H?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, C97800 or CC380H?
C97800. Its machinability rates good (58/100) against poor (28/100) for CC380H; for welding the order is CC380H first (very good, 80/100) then C97800 (poor, 25/100).
