Copper Alloy C85500-M01 vs C85500-M07

Copper Alloy · C85500 temper comparison

C85500-M01 and C85500-M07 are two conditions of the same copper alloy grade, C85500: M01 (as sand cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C85500-M07 is the stronger of the two: yield strength 190 MPa (27.6 ksi) against 172 MPa (24.9 ksi) for C85500-M01, about 10% more. In exchange, C85500-M01 is the more ductile: elongation 35% versus 28% for C85500-M07, and C85500-M07 is harder (82 HB vs 75 HB).

C85500-M01Choose it when the part is bent, formed or impact-loaded.

C85500-M07Choose it when strength drives the design.
