Copper Alloy C53800-H02 vs C53800-H06
Copper Alloy · C53800 temper comparison
C53800-H02 and C53800-H06 are two conditions of the same copper alloy grade, C53800: H02 (half hard) versus H06 (extra hard). The chemistry is identical, so every difference below comes from the condition. C53800-H06 is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 380 MPa (55.1 ksi) for C53800-H02, about 37% more; tensile strength follows at 600 MPa (87 ksi) vs 480 MPa (69.6 ksi). In exchange, C53800-H02 is the more ductile: elongation 15% versus 5% for C53800-H06, and C53800-H06 is harder (185 HB vs 145 HB).
C53800-H02Choose it when the part is bent, formed or impact-loaded.
C53800-H06Choose it when strength drives the design.
C53800-H02 vs C53800-H06: 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.

C53800-H02 vs C53800-H06 — frequently asked
Is C53800-H06 stronger than C53800-H02?
Yes. C53800-H06 has a typical yield strength of 520 MPa (75.4 ksi) against 380 MPa (55.1 ksi) for C53800-H02 — about 37% more. Tensile strength is 600 MPa (87 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, H02 or H06?
H04 is the default C53800 condition in the FabDigit quote flow (neither H02 nor H06). 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 C53800-H02 over C53800-H06?
Pick C53800-H02 when the part is bent, formed or impact-loaded. Pick C53800-H06 when strength drives the design.
