Copper Alloy CC382H vs CC383H
Copper Alloy · grade comparison
Copper Alloy CC382H 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 CC382H, about 5% more. CC383H is harder — 140 HB against 130 HB for CC382H — which matters for wear surfaces and threads. CC383H conducts heat better (29 W/m·K vs 26 W/m·K). On the shop floor, CC383H machines more easily (32 vs 22 out of 100), CC383H welds better (very good vs good), and CC383H forms better (poor vs not recommended).
CC383HChoose it when strength drives the design, or when surface hardness matters.
CC382H 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.

CC382H vs CC383H — frequently asked
Is CC383H stronger than CC382H?
Yes. CC383H has a typical yield strength of 290 MPa (42.1 ksi) against 275 MPa (39.9 ksi) for CC382H — about 5% more. Tensile strength is 480 MPa (69.6 ksi) vs 470 MPa (68.2 ksi).
Which is cheaper, CC382H 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 is easier to machine, CC382H or CC383H?
CC383H, by a small margin. Both rate poor for machinability — 32/100 against 22/100 for CC382H; for welding the order is CC383H first (very good, 80/100) then CC382H (good, 65/100).
