Copper Alloy C52100-H10 vs C52100-M20
Copper Alloy · C52100 temper comparison
C52100-H10 and C52100-M20 are two conditions of the same copper alloy grade, C52100: H10 (extra spring hard) versus M20 (as hot rolled). The chemistry is identical, so every difference below comes from the condition. C52100-H10 is the stronger of the two: yield strength 745 MPa (108 ksi) against 180 MPa (26.1 ksi) for C52100-M20, about 4.1 times as much; tensile strength follows at 815 MPa (118 ksi) vs 400 MPa (58 ksi). In exchange, C52100-M20 is the more ductile: elongation 45% versus 3% for C52100-H10, and C52100-H10 is harder (225 HB vs 70 HB). C52100-M20 runs hotter in service (200°C vs 150°C continuous). On the shop floor, C52100-M20 welds better (fair vs poor).

C52100-H10 vs C52100-M20: 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.

C52100-H10 vs C52100-M20 — frequently asked
Is C52100-H10 stronger than C52100-M20?
Yes. C52100-H10 has a typical yield strength of 745 MPa (108 ksi) against 180 MPa (26.1 ksi) for C52100-M20 — about 4.1 times as much. Tensile strength is 815 MPa (118 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, H10 or M20?
H04 is the default C52100 condition in the FabDigit quote flow (neither H10 nor M20). 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, C52100-H10 or C52100-M20?
C52100-M20. Its weldability rates fair (40/100) against poor (30/100) for C52100-H10.
