Copper Alloy C19400-H06 vs C19400-H14
Copper Alloy · C19400 temper comparison
C19400-H06 and C19400-H14 are two conditions of the same copper alloy grade, C19400: H06 (extra hard) versus H14 (strain hardened, half hard). The chemistry is identical, so every difference below comes from the condition. C19400-H14 is the stronger of the two: yield strength 565 MPa (81.9 ksi) against 460 MPa (66.7 ksi) for C19400-H06, about 23% more; tensile strength follows at 585 MPa (84.8 ksi) vs 490 MPa (71.1 ksi). In exchange, C19400-H06 is the more ductile: elongation 4% versus 2% for C19400-H14, and C19400-H14 is harder (163 HB vs 136 HB). C19400-H06 runs hotter in service (175°C vs 150°C continuous).
C19400-H06Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C19400-H14Choose it when strength drives the design.
C19400-H06 vs C19400-H14: 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.

C19400-H06 vs C19400-H14 — frequently asked
Is C19400-H14 stronger than C19400-H06?
Yes. C19400-H14 has a typical yield strength of 565 MPa (81.9 ksi) against 460 MPa (66.7 ksi) for C19400-H06 — about 23% more. Tensile strength is 585 MPa (84.8 ksi) vs 490 MPa (71.1 ksi).
Which condition does FabDigit quote by default, H06 or H14?
H02 is the default C19400 condition in the FabDigit quote flow (neither H06 nor H14). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose C19400-H06 over C19400-H14?
Pick C19400-H06 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick C19400-H14 when strength drives the design.
