Copper Alloy CC380H vs CC382H
Copper Alloy · grade comparison
Copper Alloy CC380H and CC382H are both copper alloy grades. CC382H is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 140 MPa (20.3 ksi) for CC380H, about 96% more; tensile strength follows at 470 MPa (68.2 ksi) vs 300 MPa (43.5 ksi). In exchange, CC380H is the more ductile: elongation 25% versus 20% for CC382H, and CC382H is harder (130 HB vs 80 HB). CC382H is stiffer (150 GPa vs 124 GPa) and CC380H conducts heat better (42 W/m·K vs 26 W/m·K). On the shop floor, CC380H welds better (very good vs good).
CC380HChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
CC382HChoose it when strength drives the design.
CC380H 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.

CC380H vs CC382H — frequently asked
Is CC382H stronger than CC380H?
Yes. CC382H has a typical yield strength of 275 MPa (39.9 ksi) against 140 MPa (20.3 ksi) for CC380H — about 96% more. Tensile strength is 470 MPa (68.2 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, CC380H 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 is easier to machine, CC380H or CC382H?
CC380H, by a small margin. Both rate poor for machinability — 28/100 against 22/100 for CC382H; for welding the order is CC380H first (very good, 80/100) then CC382H (good, 65/100).
