Copper Alloy C52100-H10 vs C52100-O60

Copper Alloy · C52100 temper comparison

C52100-H10 and C52100-O60 are two conditions of the same copper alloy grade, C52100: H10 (extra spring hard) versus O60 (soft annealed). 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 150 MPa (21.8 ksi) for C52100-O60, about 5.0 times as much; tensile strength follows at 815 MPa (118 ksi) vs 375 MPa (54.4 ksi). In exchange, C52100-O60 is the more ductile: elongation 62% versus 3% for C52100-H10, and C52100-H10 is harder (225 HB vs 60 HB). C52100-O60 runs hotter in service (220°C vs 150°C continuous). On the shop floor, C52100-O60 welds better (fair vs poor).

C52100-H10Choose it when strength drives the design.

C52100-O60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C52100-H10 vs C52100-O60 — frequently asked

Is C52100-H10 stronger than C52100-O60?

Yes. C52100-H10 has a typical yield strength of 745 MPa (108 ksi) against 150 MPa (21.8 ksi) for C52100-O60 — about 5.0 times as much. Tensile strength is 815 MPa (118 ksi) vs 375 MPa (54.4 ksi).

Which condition does FabDigit quote by default, H10 or O60?

H04 is the default C52100 condition in the FabDigit quote flow (neither H10 nor O60). 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, C52100-H10 or C52100-O60?

C52100-H10. Its machinability rates fair (35/100) against poor (30/100) for C52100-O60; for welding the order is C52100-O60 first (fair, 40/100) then C52100-H10 (poor, 30/100).
