Copper Alloy C99500 vs CC382H
Copper Alloy · grade comparison
Copper Alloy C99500 and CC382H are both copper alloy grades. CC382H is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 235 MPa (34.1 ksi) for C99500, about 17% more. CC382H is the more ductile: elongation 20% versus 12% for C99500. C99500 is lighter (8.2 g/cm³ vs 8.8 g/cm³ for CC382H) and CC382H is stiffer (150 GPa vs 115 GPa). On the shop floor, C99500 machines more easily (fair vs poor) and CC382H welds better (good vs fair).
C99500Choose it when weight is the constraint, or when the part is machined in volume.
CC382HChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C99500 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.

C99500 vs CC382H — frequently asked
Is CC382H stronger than C99500?
Yes. CC382H has a typical yield strength of 275 MPa (39.9 ksi) against 235 MPa (34.1 ksi) for C99500 — about 17% more. Tensile strength is 470 MPa (68.2 ksi) vs 450 MPa (65.3 ksi).
Which is cheaper, C99500 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, C99500 or CC382H?
C99500. Its machinability rates fair (35/100) against poor (22/100) for CC382H; for welding the order is CC382H first (good, 65/100) then C99500 (fair, 35/100).
