Copper Alloy C22000-H01 vs C22000-M20
Copper Alloy · C22000 temper comparison
C22000-H01 and C22000-M20 are two conditions of the same copper alloy grade, C22000: H01 (quarter hard) versus M20 (as hot rolled). The chemistry is identical, so every difference below comes from the condition. C22000-H01 is the stronger of the two: yield strength 215 MPa (31.2 ksi) against 85 MPa (12.3 ksi) for C22000-M20, about 153% more; tensile strength follows at 305 MPa (44.2 ksi) vs 260 MPa (37.7 ksi). In exchange, C22000-M20 is the more ductile: elongation 45% versus 35% for C22000-H01, and C22000-H01 is harder (90 HB vs 52 HB). C22000-M20 runs hotter in service (250°C vs 180°C continuous). On the shop floor, C22000-M20 welds better (good vs fair).
C22000-H01Choose it when strength drives the design.
C22000-M20Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C22000-H01 vs C22000-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.

C22000-H01 vs C22000-M20 — frequently asked
Is C22000-H01 stronger than C22000-M20?
Yes. C22000-H01 has a typical yield strength of 215 MPa (31.2 ksi) against 85 MPa (12.3 ksi) for C22000-M20 — about 153% more. Tensile strength is 305 MPa (44.2 ksi) vs 260 MPa (37.7 ksi).
Which condition does FabDigit quote by default, H01 or M20?
O is the default C22000 condition in the FabDigit quote flow (neither H01 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 is easier to machine, C22000-H01 or C22000-M20?
C22000-H01. Its machinability rates fair (35/100) against poor (26/100) for C22000-M20; for welding the order is C22000-M20 first (good, 55/100) then C22000-H01 (fair, 45/100).
