Copper Alloy C76200-H01 vs C76200-H02
Copper Alloy · C76200 temper comparison
C76200-H01 and C76200-H02 are two conditions of the same copper alloy grade, C76200: H01 (quarter hard) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. C76200-H02 is the stronger of the two: yield strength 448 MPa (65 ksi) against 310 MPa (45 ksi) for C76200-H01, about 45% more; tensile strength follows at 517 MPa (75 ksi) vs 450 MPa (65.3 ksi). In exchange, C76200-H01 is the more ductile: elongation 25% versus 10% for C76200-H02, and C76200-H02 is harder (155 HB vs 130 HB). C76200-H01 runs hotter in service (200°C vs 175°C continuous).
C76200-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C76200-H02Choose it when strength drives the design.
C76200-H01 vs C76200-H02: 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.

C76200-H01 vs C76200-H02 — frequently asked
Is C76200-H02 stronger than C76200-H01?
Yes. C76200-H02 has a typical yield strength of 448 MPa (65 ksi) against 310 MPa (45 ksi) for C76200-H01 — about 45% more. Tensile strength is 517 MPa (75 ksi) vs 450 MPa (65.3 ksi).
Which condition does FabDigit quote by default, H01 or H02?
H02 is the default C76200 condition in the FabDigit quote flow. 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 C76200-H01 over C76200-H02?
Pick C76200-H01 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick C76200-H02 when strength drives the design.
