Copper Alloy C10100-H01 vs C10100-O

Copper Alloy · C10100 temper comparison

C10100-H01 and C10100-O are two conditions of the same copper alloy grade, C10100: H01 (quarter hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. C10100-H01 is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 69 MPa (10 ksi) for C10100-O, about 3.2 times as much; tensile strength follows at 275 MPa (39.9 ksi) vs 235 MPa (34.1 ksi). In exchange, C10100-O is the more ductile: elongation 45% versus 25% for C10100-H01, and C10100-H01 is harder (70 HB vs 45 HB). C10100-O runs hotter in service (200°C vs 175°C continuous).

C10100-H01Choose it when strength drives the design.

C10100-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C10100-H01 vs C10100-O — frequently asked

Is C10100-H01 stronger than C10100-O?

Yes. C10100-H01 has a typical yield strength of 220 MPa (31.9 ksi) against 69 MPa (10 ksi) for C10100-O — about 3.2 times as much. Tensile strength is 275 MPa (39.9 ksi) vs 235 MPa (34.1 ksi).

Which condition does FabDigit quote by default, H01 or O?

O is the default C10100 condition in the FabDigit quote flow. 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, C10100-H01 or C10100-O?

C10100-H01, by a small margin. Both rate poor for machinability — 24/100 against 18/100 for C10100-O; for welding the order is C10100-O first (very good, 70/100) then C10100-H01 (good, 65/100).
