Copper Alloy C10300-H01 vs C10300-H02
Copper Alloy · C10300 temper comparison
C10300-H01 and C10300-H02 are two conditions of the same copper alloy grade, C10300: H01 (quarter hard) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. C10300-H02 is the stronger of the two: yield strength 245 MPa (35.5 ksi) against 205 MPa (29.7 ksi) for C10300-H01, about 20% more; tensile strength follows at 280 MPa (40.6 ksi) vs 262 MPa (38 ksi). In exchange, C10300-H01 is the more ductile: elongation 25% versus 14% for C10300-H02, and C10300-H02 is harder (78 HB vs 68 HB).
C10300-H01Choose it when the part is bent, formed or impact-loaded.
C10300-H02Choose it when strength drives the design.
C10300-H01 vs C10300-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.

C10300-H01 vs C10300-H02 — frequently asked
Is C10300-H02 stronger than C10300-H01?
Yes. C10300-H02 has a typical yield strength of 245 MPa (35.5 ksi) against 205 MPa (29.7 ksi) for C10300-H01 — about 20% more. Tensile strength is 280 MPa (40.6 ksi) vs 262 MPa (38 ksi).
Which condition does FabDigit quote by default, H01 or H02?
O60 is the default C10300 condition in the FabDigit quote flow (neither H01 nor H02). 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.
Which welds better, C10300-H01 or C10300-H02?
C10300-H01. Its weldability rates excellent (85/100) against very good (80/100) for C10300-H02.
