Copper Alloy C46200-H02 vs C46200-H04
Copper Alloy · C46200 temper comparison
C46200-H02 and C46200-H04 are two conditions of the same copper alloy grade, C46200: H02 (half hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. C46200-H04 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 360 MPa (52.2 ksi) for C46200-H02, about 15% more; tensile strength follows at 560 MPa (81.2 ksi) vs 470 MPa (68.2 ksi). In exchange, C46200-H02 is the more ductile: elongation 20% versus 15% for C46200-H04, and C46200-H04 is harder (180 HB vs 150 HB). C46200-H02 runs hotter in service (175°C vs 150°C continuous).
C46200-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C46200-H04Choose it when strength drives the design.
C46200-H02 vs C46200-H04: 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.

C46200-H02 vs C46200-H04 — frequently asked
Is C46200-H04 stronger than C46200-H02?
Yes. C46200-H04 has a typical yield strength of 415 MPa (60.2 ksi) against 360 MPa (52.2 ksi) for C46200-H02 — about 15% more. Tensile strength is 560 MPa (81.2 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, H02 or H04?
M30 is the default C46200 condition in the FabDigit quote flow (neither H02 nor H04). 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 C46200-H02 over C46200-H04?
Pick C46200-H02 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick C46200-H04 when strength drives the design.
