Copper Alloy C96700 vs CC380H
Copper Alloy · grade comparison
Copper Alloy C96700 and CC380H are both copper alloy grades. C96700 is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 140 MPa (20.3 ksi) for CC380H, about 4.4 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 C96700, and C96700 is harder (330 HB vs 80 HB). C96700 is stiffer (152 GPa vs 124 GPa) and CC380H conducts heat better (42 W/m·K vs 33 W/m·K). On the shop floor, CC380H welds better (very good vs fair).
C96700Choose it when strength drives the design.
CC380HChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
C96700 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.

C96700 vs CC380H — frequently asked
Is C96700 stronger than CC380H?
Yes. C96700 has a typical yield strength of 620 MPa (89.9 ksi) against 140 MPa (20.3 ksi) for CC380H — about 4.4 times as much. Tensile strength is 760 MPa (110 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, C96700 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, C96700 or CC380H?
CC380H. Its weldability rates very good (80/100) against fair (35/100) for C96700.
