Copper Alloy C84200-M05 vs C84200-M06

Copper Alloy · C84200 temper comparison

C84200-M05 and C84200-M06 are two conditions of the same copper alloy grade, C84200: M05 (as plaster cast) versus M06 (as investment cast). The chemistry is identical, so every difference below comes from the condition. C84200-M05 is the stronger of the two: yield strength 110 MPa (16 ksi) against 103 MPa (14.9 ksi) for C84200-M06, about 7% more; tensile strength follows at 255 MPa (37 ksi) vs 241 MPa (35 ksi). C84200-M05 is harder — 58 HB against 55 HB for C84200-M06 — which matters for wear surfaces and threads.

C84200-M05Choose it when strength drives the design, or when surface hardness matters.

C84200-M05 vs C84200-M06 — frequently asked

Is C84200-M05 stronger than C84200-M06?

Yes. C84200-M05 has a typical yield strength of 110 MPa (16 ksi) against 103 MPa (14.9 ksi) for C84200-M06 — about 7% more. Tensile strength is 255 MPa (37 ksi) vs 241 MPa (35 ksi).

Which condition does FabDigit quote by default, M05 or M06?

M01 is the default C84200 condition in the FabDigit quote flow (neither M05 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 C84200-M05 over C84200-M06?

Pick C84200-M05 when strength drives the design, or when surface hardness matters.
