Copper Alloy C96400 vs CC382H
Copper Alloy · grade comparison
Copper Alloy C96400 and CC382H are both copper alloy grades. Both yield at about 265 MPa — strength does not separate them. C96400 is the more ductile: elongation 25% versus 20% for CC382H, and C96400 is harder (140 HB vs 130 HB). On the shop floor, C96400 welds better (very good vs good).
C96400Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C96400 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.

C96400 vs CC382H — frequently asked
What is the difference between C96400 and CC382H?
Copper Alloy C96400 and CC382H are both copper alloy grades. Both yield at about 265 MPa — strength does not separate them. C96400 is the more ductile: elongation 25% versus 20% for CC382H, and C96400 is harder (140 HB vs 130 HB).
Which is cheaper, C96400 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 welds better, C96400 or CC382H?
C96400. Its weldability rates very good (80/100) against good (65/100) for CC382H.
