Copper Alloy C15100-H01 vs C15100-H04
Copper Alloy · C15100 temper comparison
C15100-H01 and C15100-H04 are two conditions of the same copper alloy grade, C15100: H01 (quarter hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. C15100-H04 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 215 MPa (31.2 ksi) for C15100-H01, about 53% more; tensile strength follows at 360 MPa (52.2 ksi) vs 275 MPa (39.9 ksi). In exchange, C15100-H01 is the more ductile: elongation 25% versus 6% for C15100-H04, and C15100-H04 is harder (105 HB vs 70 HB).
C15100-H01Choose it when the part is bent, formed or impact-loaded.
C15100-H04Choose it when strength drives the design.
C15100-H01 vs C15100-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.

C15100-H01 vs C15100-H04 — frequently asked
Is C15100-H04 stronger than C15100-H01?
Yes. C15100-H04 has a typical yield strength of 330 MPa (47.9 ksi) against 215 MPa (31.2 ksi) for C15100-H01 — about 53% more. Tensile strength is 360 MPa (52.2 ksi) vs 275 MPa (39.9 ksi).
Which condition does FabDigit quote by default, H01 or H04?
H04 is the default C15100 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 C15100-H01 over C15100-H04?
Pick C15100-H01 when the part is bent, formed or impact-loaded. Pick C15100-H04 when strength drives the design.
