Copper Alloy C97800-M02 vs C97800-M06

Copper Alloy · C97800 temper comparison

C97800-M02 and C97800-M06 are two conditions of the same copper alloy grade, C97800: M02 (as centrifugally cast) versus M06 (as investment cast). The chemistry is identical, so every difference below comes from the condition. C97800-M02 is the stronger of the two: yield strength 240 MPa (34.8 ksi) against 225 MPa (32.6 ksi) for C97800-M06, about 7% more; tensile strength follows at 425 MPa (61.6 ksi) vs 400 MPa (58 ksi). C97800-M02 is the more ductile: elongation 15% versus 13% for C97800-M06.

C97800-M02Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

C97800-M02 vs C97800-M06 — frequently asked

Is C97800-M02 stronger than C97800-M06?

Yes. C97800-M02 has a typical yield strength of 240 MPa (34.8 ksi) against 225 MPa (32.6 ksi) for C97800-M06 — about 7% more. Tensile strength is 425 MPa (61.6 ksi) vs 400 MPa (58 ksi).

Which condition does FabDigit quote by default, M02 or M06?

M01 is the default C97800 condition in the FabDigit quote flow (neither M02 nor M06). 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 C97800-M02 over C97800-M06?

Pick C97800-M02 when strength drives the design, or when the part is bent, formed or impact-loaded.
