Copper Alloy C79600-H01 vs C79600-M30
Copper Alloy · C79600 temper comparison
C79600-H01 and C79600-M30 are two conditions of the same copper alloy grade, C79600: H01 (quarter hard) versus M30 (as hot extruded). The chemistry is identical, so every difference below comes from the condition. C79600-H01 is the stronger of the two: yield strength 310 MPa (45 ksi) against 210 MPa (30.5 ksi) for C79600-M30, about 48% more; tensile strength follows at 480 MPa (69.6 ksi) vs 450 MPa (65.3 ksi). In exchange, C79600-M30 is the more ductile: elongation 25% versus 22% for C79600-H01, and C79600-H01 is harder (140 HB vs 125 HB). C79600-M30 runs hotter in service (200°C vs 180°C continuous).
C79600-H01Choose it when strength drives the design.
C79600-M30Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C79600-H01 vs C79600-M30: 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.

C79600-H01 vs C79600-M30 — frequently asked
Is C79600-H01 stronger than C79600-M30?
Yes. C79600-H01 has a typical yield strength of 310 MPa (45 ksi) against 210 MPa (30.5 ksi) for C79600-M30 — about 48% more. Tensile strength is 480 MPa (69.6 ksi) vs 450 MPa (65.3 ksi).
Which condition does FabDigit quote by default, H01 or M30?
H02 is the default C79600 condition in the FabDigit quote flow (neither H01 nor M30). 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 C79600-H01 over C79600-M30?
Pick C79600-H01 when strength drives the design. Pick C79600-M30 when the part is bent, formed or impact-loaded, or when the part sees heat.
