Copper Alloy C96300 vs CC383H
Copper Alloy · grade comparison
Copper Alloy C96300 and CC383H are both copper alloy grades. CC383H is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 275 MPa (39.9 ksi) for C96300, about 5% more. CC383H is the more ductile: elongation 22% versus 18% for C96300. C96300 conducts heat better (33 W/m·K vs 29 W/m·K).
CC383HChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C96300 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.

C96300 vs CC383H — frequently asked
Is CC383H stronger than C96300?
Yes. CC383H has a typical yield strength of 290 MPa (42.1 ksi) against 275 MPa (39.9 ksi) for C96300 — about 5% more. Tensile strength is 480 MPa (69.6 ksi) vs 470 MPa (68.2 ksi).
Which is cheaper, C96300 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, C96300 or CC383H?
CC383H. Its weldability rates very good (80/100) against very good (75/100) for C96300.
