Copper Alloy C46500-H02 vs C46500-M30
Copper Alloy · C46500 temper comparison
C46500-H02 and C46500-M30 are two conditions of the same copper alloy grade, C46500: H02 (half hard) versus M30 (as hot extruded). The chemistry is identical, so every difference below comes from the condition. C46500-H02 is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 170 MPa (24.7 ksi) for C46500-M30, about 100% more; tensile strength follows at 480 MPa (69.6 ksi) vs 380 MPa (55.1 ksi). In exchange, C46500-M30 is the more ductile: elongation 40% versus 20% for C46500-H02, and C46500-H02 is harder (130 HB vs 92 HB). C46500-M30 runs hotter in service (200°C vs 160°C continuous).
C46500-H02Choose it when strength drives the design.
C46500-M30Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C46500-H02 vs C46500-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.

C46500-H02 vs C46500-M30 — frequently asked
Is C46500-H02 stronger than C46500-M30?
Yes. C46500-H02 has a typical yield strength of 340 MPa (49.3 ksi) against 170 MPa (24.7 ksi) for C46500-M30 — about 100% more. Tensile strength is 480 MPa (69.6 ksi) vs 380 MPa (55.1 ksi).
Which condition does FabDigit quote by default, H02 or M30?
M20 is the default C46500 condition in the FabDigit quote flow (neither H02 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 C46500-H02 over C46500-M30?
Pick C46500-H02 when strength drives the design. Pick C46500-M30 when the part is bent, formed or impact-loaded, or when the part sees heat.
