Copper Alloy C96600 vs CC383H
Copper Alloy · grade comparison
Copper Alloy C96600 and CC383H are both copper alloy grades. C96600 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 290 MPa (42.1 ksi) for CC383H, about 102% more; tensile strength follows at 760 MPa (110 ksi) vs 480 MPa (69.6 ksi). In exchange, CC383H is the more ductile: elongation 22% versus 5% for C96600, and C96600 is harder (285 HB vs 140 HB). C96600 runs hotter in service (330°C vs 300°C continuous) and C96600 conducts heat better (42 W/m·K vs 29 W/m·K). On the shop floor, CC383H welds better (very good vs fair).
C96600Choose it when strength drives the design, or when the part sees heat.
CC383HChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
C96600 vs CC383H: 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 CC383H — frequently asked
Is C96600 stronger than CC383H?
Yes. C96600 has a typical yield strength of 585 MPa (84.8 ksi) against 290 MPa (42.1 ksi) for CC383H — about 102% more. Tensile strength is 760 MPa (110 ksi) vs 480 MPa (69.6 ksi).
Which is cheaper, C96600 or CC383H?
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 CC383H?
CC383H. Its weldability rates very good (80/100) against fair (35/100) for C96600.
