Copper Alloy C1100-F vs C1100-H

Copper Alloy · C1100 temper comparison

C1100-F and C1100-H are two conditions of the same copper alloy grade, C1100: F (as fabricated) versus H (hardened). The chemistry is identical, so every difference below comes from the condition. C1100-H is the stronger of the two: yield strength 305 MPa (44.2 ksi) against 75 MPa (10.9 ksi) for C1100-F, about 4.1 times as much; tensile strength follows at 345 MPa (50 ksi) vs 215 MPa (31.2 ksi). In exchange, C1100-F is the more ductile: elongation 42% versus 6% for C1100-H, and C1100-H is harder (112 HV vs 50 HV). C1100-F runs hotter in service (200°C vs 150°C continuous). On the shop floor, C1100-H machines more easily (32 vs 20 out of 100).

C1100-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C1100-HChoose it when strength drives the design, or when the part is machined in volume.

C1100-F vs C1100-H — frequently asked

Is C1100-H stronger than C1100-F?

Yes. C1100-H has a typical yield strength of 305 MPa (44.2 ksi) against 75 MPa (10.9 ksi) for C1100-F — about 4.1 times as much. Tensile strength is 345 MPa (50 ksi) vs 215 MPa (31.2 ksi).

Which condition does FabDigit quote by default, F or H?

O is the default C1100 condition in the FabDigit quote flow (neither F nor H). 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, C1100-F or C1100-H?

C1100-H, by a small margin. Both rate poor for machinability — 32/100 against 20/100 for C1100-F.
