Copper Alloy C96700 vs CC382H
Copper Alloy · grade comparison
Copper Alloy C96700 and CC382H are both copper alloy grades. C96700 is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 275 MPa (39.9 ksi) for CC382H, about 125% more; tensile strength follows at 760 MPa (110 ksi) vs 470 MPa (68.2 ksi). In exchange, CC382H is the more ductile: elongation 20% versus 5% for C96700, and C96700 is harder (330 HB vs 130 HB). C96700 conducts heat better (33 W/m·K vs 26 W/m·K). On the shop floor, CC382H welds better (good vs fair).
C96700Choose it when strength drives the design.
CC382HChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
C96700 vs CC382H: 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 CC382H — frequently asked
Is C96700 stronger than CC382H?
Yes. C96700 has a typical yield strength of 620 MPa (89.9 ksi) against 275 MPa (39.9 ksi) for CC382H — about 125% more. Tensile strength is 760 MPa (110 ksi) vs 470 MPa (68.2 ksi).
Which is cheaper, C96700 or CC382H?
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 CC382H?
CC382H. Its weldability rates good (65/100) against fair (35/100) for C96700.
