Copper Alloy C99500-M01 vs C99500-M07

Copper Alloy · C99500 temper comparison

C99500-M01 and C99500-M07 are two conditions of the same copper alloy grade, C99500: M01 (as sand cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C99500-M07 is the stronger of the two: yield strength 255 MPa (37 ksi) against 235 MPa (34.1 ksi) for C99500-M01, about 9% more; tensile strength follows at 480 MPa (69.6 ksi) vs 450 MPa (65.3 ksi). C99500-M07 is harder — 145 HB against 135 HB for C99500-M01 — which matters for wear surfaces and threads.

C99500-M07Choose it when strength drives the design, or when surface hardness matters.
