Copper Alloy C86400-M01 vs C86400-M07

Copper Alloy · C86400 temper comparison

C86400-M01 and C86400-M07 are two conditions of the same copper alloy grade, C86400: M01 (as sand cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C86400-M07 is the stronger of the two: yield strength 241 MPa (35 ksi) against 193 MPa (28 ksi) for C86400-M01, about 25% more; tensile strength follows at 483 MPa (70.1 ksi) vs 448 MPa (65 ksi). In exchange, C86400-M01 is the more ductile: elongation 20% versus 15% for C86400-M07, and C86400-M07 is harder (105 HB vs 90 HB).

C86400-M01Choose it when the part is bent, formed or impact-loaded.

C86400-M07Choose it when strength drives the design.
