Copper Alloy C11000-H02 vs C11000-O

Copper Alloy · C11000 temper comparison

C11000-H02 and C11000-O are two conditions of the same copper alloy grade, C11000: H02 (half hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. C11000-H02 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 69 MPa (10 ksi) for C11000-O, about 3.6 times as much; tensile strength follows at 290 MPa (42.1 ksi) vs 221 MPa (32.1 ksi). In exchange, C11000-O is the more ductile: elongation 45% versus 14% for C11000-H02, and C11000-H02 is harder (85 HB vs 45 HB). C11000-O runs hotter in service (250°C vs 150°C continuous).

C11000-H02Choose it when strength drives the design.

C11000-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C11000-H02 vs C11000-O — frequently asked

Is C11000-H02 stronger than C11000-O?

Yes. C11000-H02 has a typical yield strength of 250 MPa (36.3 ksi) against 69 MPa (10 ksi) for C11000-O — about 3.6 times as much. Tensile strength is 290 MPa (42.1 ksi) vs 221 MPa (32.1 ksi).

Which condition does FabDigit quote by default, H02 or O?

O is the default C11000 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.

When should I choose C11000-H02 over C11000-O?

Pick C11000-H02 when strength drives the design. Pick C11000-O when the part is bent, formed or impact-loaded, or when the part sees heat.
