Copper Alloy C80100-M03 vs C80100-M07

Copper Alloy · C80100 temper comparison

C80100-M03 and C80100-M07 are two conditions of the same copper alloy grade, C80100: M03 (as chill cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C80100-M07 is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 62 MPa (8.99 ksi) for C80100-M03, about 45% more; tensile strength follows at 200 MPa (29 ksi) vs 170 MPa (24.7 ksi). In exchange, C80100-M03 is the more ductile: elongation 40% versus 35% for C80100-M07, and C80100-M07 is harder (55 HB vs 42 HB).

C80100-M03Choose it when the part is bent, formed or impact-loaded.

C80100-M07Choose it when strength drives the design.

C80100-M03 vs C80100-M07 — frequently asked

Is C80100-M07 stronger than C80100-M03?

Yes. C80100-M07 has a typical yield strength of 90 MPa (13.1 ksi) against 62 MPa (8.99 ksi) for C80100-M03 — about 45% more. Tensile strength is 200 MPa (29 ksi) vs 170 MPa (24.7 ksi).

Which condition does FabDigit quote by default, M03 or M07?

M01 is the default C80100 condition in the FabDigit quote flow (neither M03 nor M07). 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 C80100-M03 over C80100-M07?

Pick C80100-M03 when the part is bent, formed or impact-loaded. Pick C80100-M07 when strength drives the design.
