Copper Alloy C89320-M01 vs C89320-M06

Copper Alloy · C89320 temper comparison

C89320-M01 and C89320-M06 are two conditions of the same copper alloy grade, C89320: M01 (as sand cast) versus M06 (as investment cast). The chemistry is identical, so every difference below comes from the condition. C89320-M06 is the stronger of the two: yield strength 138 MPa (20 ksi) against 117 MPa (17 ksi) for C89320-M01, about 18% more; tensile strength follows at 262 MPa (38 ksi) vs 241 MPa (35 ksi). C89320-M06 is harder — 66 HB against 60 HB for C89320-M01 — which matters for wear surfaces and threads.

C89320-M06Choose it when strength drives the design, or when surface hardness matters.
