Copper Alloy C50100-H02 vs C50100-H08
Copper Alloy · C50100 temper comparison
C50100-H02 and C50100-H08 are two conditions of the same copper alloy grade, C50100: H02 (half hard) versus H08 (spring hard). The chemistry is identical, so every difference below comes from the condition. C50100-H08 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 290 MPa (42.1 ksi) for C50100-H02, about 43% more; tensile strength follows at 450 MPa (65.3 ksi) vs 345 MPa (50 ksi). In exchange, C50100-H02 is the more ductile: elongation 15% versus 4% for C50100-H08, and C50100-H08 is harder (135 HB vs 100 HB). C50100-H02 runs hotter in service (200°C vs 150°C continuous). On the shop floor, C50100-H02 welds better (good vs fair).
C50100-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C50100-H08Choose it when strength drives the design.
C50100-H02 vs C50100-H08: 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.

C50100-H02 vs C50100-H08 — frequently asked
Is C50100-H08 stronger than C50100-H02?
Yes. C50100-H08 has a typical yield strength of 415 MPa (60.2 ksi) against 290 MPa (42.1 ksi) for C50100-H02 — about 43% more. Tensile strength is 450 MPa (65.3 ksi) vs 345 MPa (50 ksi).
Which condition does FabDigit quote by default, H02 or H08?
H04 is the default C50100 condition in the FabDigit quote flow (neither H02 nor H08). 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, C50100-H02 or C50100-H08?
C50100-H02. Its weldability rates good (60/100) against fair (50/100) for C50100-H08.
