Copper Alloy C96400 vs CC380H
Copper Alloy · grade comparison
Copper Alloy C96400 and CC380H are both copper alloy grades. C96400 is the stronger of the two: yield strength 265 MPa (38.4 ksi) against 140 MPa (20.3 ksi) for CC380H, about 89% more; tensile strength follows at 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi). C96400 is harder — 140 HB against 80 HB for CC380H — which matters for wear surfaces and threads. C96400 is stiffer (152 GPa vs 124 GPa) and CC380H conducts heat better (42 W/m·K vs 28 W/m·K).
C96400Choose it when strength drives the design, or when surface hardness matters.
C96400 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.

C96400 vs CC380H — frequently asked
Is C96400 stronger than CC380H?
Yes. C96400 has a typical yield strength of 265 MPa (38.4 ksi) against 140 MPa (20.3 ksi) for CC380H — about 89% more. Tensile strength is 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, C96400 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.
When should I choose C96400 over CC380H?
Pick C96400 when strength drives the design, or when surface hardness matters.
