Copper Alloy C83800-M02 vs C83800-M06

Copper Alloy · C83800 temper comparison

C83800-M02 and C83800-M06 are two conditions of the same copper alloy grade, C83800: M02 (as centrifugally cast) versus M06 (as investment cast). The chemistry is identical, so every difference below comes from the condition. C83800-M02 is the stronger of the two: yield strength 117 MPa (17 ksi) against 110 MPa (16 ksi) for C83800-M06, about 6% more; tensile strength follows at 255 MPa (37 ksi) vs 241 MPa (35 ksi). C83800-M02 is harder — 60 HB against 55 HB for C83800-M06 — which matters for wear surfaces and threads.

C83800-M02Choose it when strength drives the design, or when surface hardness matters.

C83800-M02 vs C83800-M06 — frequently asked

Is C83800-M02 stronger than C83800-M06?

Yes. C83800-M02 has a typical yield strength of 117 MPa (17 ksi) against 110 MPa (16 ksi) for C83800-M06 — about 6% more. Tensile strength is 255 MPa (37 ksi) vs 241 MPa (35 ksi).

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

M01 is the default C83800 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 C83800-M02 over C83800-M06?

Pick C83800-M02 when strength drives the design, or when surface hardness matters.
