Copper Alloy C80300-M02 vs C80300-M06

Copper Alloy · C80300 temper comparison

C80300-M02 and C80300-M06 are two conditions of the same copper alloy grade, C80300: M02 (as centrifugally cast) versus M06 (as investment cast). The chemistry is identical, so every difference below comes from the condition. C80300-M02 is the stronger of the two: tensile strength 185 MPa (26.8 ksi) against 172 MPa (24.9 ksi) for C80300-M06, about 8% more.
