Copper Alloy CC380H vs CC383H
Copper Alloy · grade comparison
Copper Alloy CC380H and CC383H are both copper alloy grades. CC383H is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 140 MPa (20.3 ksi) for CC380H, about 107% more; tensile strength follows at 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi). In exchange, CC380H is the more ductile: elongation 25% versus 22% for CC383H, and CC383H is harder (140 HB vs 80 HB). CC383H is stiffer (150 GPa vs 124 GPa) and CC380H conducts heat better (42 W/m·K vs 29 W/m·K).
CC380HChoose it when the part is bent, formed or impact-loaded.
CC383HChoose it when strength drives the design.
CC380H 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.

CC380H vs CC383H — frequently asked
Is CC383H stronger than CC380H?
Yes. CC383H has a typical yield strength of 290 MPa (42.1 ksi) against 140 MPa (20.3 ksi) for CC380H — about 107% more. Tensile strength is 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, CC380H 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.
When should I choose CC380H over CC383H?
Pick CC380H when the part is bent, formed or impact-loaded. Pick CC383H when strength drives the design.
