Copper Alloy C87500-M01 vs C87500-M07

Copper Alloy · C87500 temper comparison

C87500-M01 and C87500-M07 are two conditions of the same copper alloy grade, C87500: M01 (as sand cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C87500-M07 is the stronger of the two: yield strength 245 MPa (35.5 ksi) against 225 MPa (32.6 ksi) for C87500-M01, about 9% more; tensile strength follows at 470 MPa (68.2 ksi) vs 440 MPa (63.8 ksi). C87500-M07 is harder — 115 HB against 100 HB for C87500-M01 — which matters for wear surfaces and threads.

C87500-M07Choose it when strength drives the design, or when surface hardness matters.
