Copper Alloy C41300-H01 vs C41300-H04
Copper Alloy · C41300 temper comparison
C41300-H01 and C41300-H04 are two conditions of the same copper alloy grade, C41300: H01 (quarter hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. C41300-H04 is the stronger of the two: yield strength 483 MPa (70.1 ksi) against 330 MPa (47.9 ksi) for C41300-H01, about 46% more; tensile strength follows at 524 MPa (76 ksi) vs 400 MPa (58 ksi). In exchange, C41300-H01 is the more ductile: elongation 18% versus 4% for C41300-H04, and C41300-H04 is harder (158 HB vs 105 HB). C41300-H01 runs hotter in service (190°C vs 165°C continuous).
C41300-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C41300-H04Choose it when strength drives the design.
C41300-H01 vs C41300-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.

C41300-H01 vs C41300-H04 — frequently asked
Is C41300-H04 stronger than C41300-H01?
Yes. C41300-H04 has a typical yield strength of 483 MPa (70.1 ksi) against 330 MPa (47.9 ksi) for C41300-H01 — about 46% more. Tensile strength is 524 MPa (76 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, H01 or H04?
H02 is the default C41300 condition in the FabDigit quote flow (neither H01 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 C41300-H01 over C41300-H04?
Pick C41300-H01 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick C41300-H04 when strength drives the design.
