Copper Alloy C15900-H02 vs C15900-HIP
Copper Alloy · C15900 temper comparison
C15900-H02 and C15900-HIP are two conditions of the same copper alloy grade, C15900: H02 (half hard) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. C15900-H02 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 310 MPa (45 ksi) for C15900-HIP, about 52% more; tensile strength follows at 515 MPa (74.7 ksi) vs 400 MPa (58 ksi). In exchange, C15900-HIP is the more ductile: elongation 22% versus 14% for C15900-H02, and C15900-H02 is harder (138 HB vs 105 HB). C15900-HIP runs hotter in service (550°C vs 500°C continuous).
C15900-H02Choose it when strength drives the design.
C15900-HIPChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C15900-H02 vs C15900-HIP: 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.

C15900-H02 vs C15900-HIP — frequently asked
Is C15900-H02 stronger than C15900-HIP?
Yes. C15900-H02 has a typical yield strength of 470 MPa (68.2 ksi) against 310 MPa (45 ksi) for C15900-HIP — about 52% more. Tensile strength is 515 MPa (74.7 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, H02 or HIP?
H04 is the default C15900 condition in the FabDigit quote flow (neither H02 nor HIP). 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 C15900-H02 over C15900-HIP?
Pick C15900-H02 when strength drives the design. Pick C15900-HIP when the part is bent, formed or impact-loaded, or when the part sees heat.
