Copper Alloy C91000-M01 vs C91000-M10

Copper Alloy · C91000 temper comparison

C91000-M01 and C91000-M10 are two conditions of the same copper alloy grade, C91000: M01 (as sand cast) versus M10 (as hot forged and air cooled). The chemistry is identical, so every difference below comes from the condition. C91000-M10 is the stronger of the two: yield strength 160 MPa (23.2 ksi) against 150 MPa (21.8 ksi) for C91000-M01, about 7% more; tensile strength follows at 240 MPa (34.8 ksi) vs 225 MPa (32.6 ksi). C91000-M10 is harder — 145 HB against 135 HB for C91000-M01 — which matters for wear surfaces and threads.

C91000-M10Choose it when strength drives the design, or when surface hardness matters.
