Copper Alloy C96600 vs CC380H
Copper Alloy · grade comparison
Copper Alloy C96600 and CC380H are both copper alloy grades. C96600 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 140 MPa (20.3 ksi) for CC380H, about 4.2 times as much; tensile strength follows at 760 MPa (110 ksi) vs 300 MPa (43.5 ksi). In exchange, CC380H is the more ductile: elongation 25% versus 5% for C96600, and C96600 is harder (285 HB vs 80 HB). C96600 is stiffer (150 GPa vs 124 GPa) and C96600 runs hotter in service (330°C vs 300°C continuous). On the shop floor, CC380H welds better (very good vs fair).
C96600Choose it when strength drives the design, or when the part sees heat.
CC380HChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
C96600 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.

C96600 vs CC380H — frequently asked
Is C96600 stronger than CC380H?
Yes. C96600 has a typical yield strength of 585 MPa (84.8 ksi) against 140 MPa (20.3 ksi) for CC380H — about 4.2 times as much. Tensile strength is 760 MPa (110 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, C96600 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 welds better, C96600 or CC380H?
CC380H. Its weldability rates very good (80/100) against fair (35/100) for C96600.
